Crawford Access and Automation
Increase your efficiency, safety and comfort!
All manual Crawford doors can be upgraded with operators and automation. To facilitate quick access, a wide range of options are available, such as pushbuttons, pull ropes, transmitters, magnetic loops, photocells, radar or automatic closing. Customer needs in focus The demand for efficient logistic flow is one of the most important factors in the manufacturing and distribution industry. With a remote control, radar or other access options, drivers do not have to leave their vehicles. This increases the efficiency of the material handling process. The smooth action of doors also extends door lifetime by reducing mechanical wear and tear and contributes to a pleasant working environment. Automated opening of bigger doors means preventing exposure of the human body to unnecessary strain. Automation also reduces energy costs by limiting the time the door is open to the absolute minimum. An investment in doors equipped with remote control, radar or other access options quickly pays off. Not only does it save money, it improves the working environment and increases safety as well as efficiency. Door economy Electrically operated doors save money. Doors equipped with remote control, radar or other access options are a valuable investment. Not only do they save money, they improve the working environment and increase safety as well as efficiency. Very often, the purchase price is brought into focus while less attention is paid to the user cost. The user cost can be broken down into: - floor area costs - down time costs - maintenance costs - repair costs - passage costs - costs for heat losses - capital costs Of these costs, the passage costs represent between 30-50% while costs for heat losses and capital account for a much smaller part. Automation is the major cost cutting factor in door economy and an investment with rapid payback time. Safety and access Doors equipped with automation options offers a high level of safety and an improved working environment as every operation is controlled. Crawford s long experience of powerdriven doors has resulted in an extensive and well-tested safety systems. A series of safety devices for stopping, reversing, locking, monitoring and controlled operating ensures high safety when the door is in use. Crawford has a number of solutions for limiting access. Our automation program allows the user to choose any level of access, from low-level applications to highly restricted entry, with a personal code opening procedure. In the event of a power cut, the operator unit can easily be disengaged and the door operated manually. Quality assurance All electrically operated products made by Crawford are CE-marked in accordance with the applicable European Directives and produced under an ISO 9001 certified quality management system as well as an ISO 14001 environmental management system.

Push button Pull rope Remote control

Magnetic loops

Photo cells
Push button The most widely used method of operating the doors. A variety of types are available including key control. Can be fitted with programmed automatic closing and together with photocells. Various access level possibilities. Pull rope The pull rope allows vehicle drivers to operate the door from a more convenient position. The pull rope generally hangs from a bracket extending approximately 3meters from the wall. Can be fitted with a programmed automatic closing and together with photocells. Unlimited access.
Remote control A modern, simple and safe system. A radio transmitter is used to control the door. Access is limited to those having the transmitter. The system allows more restricted access, if required. One transmitter can operate any number of doors. Can be fitted with programmed automatic closing and together with photocells. Fixed transmitter Same system as remote control but with the transmitter mounted in the vehicle.

Magnetic loop The door is opened or closed by vehicles activating a magnetic loop in the ground. Can be fitted with programmed automatic closing and together with photocells. Unlimited access for vehicles. Photocells The opening and closing of the door is controlled by a photocell placed outside and/or inside the door opening. Can be fitted with programmed automatic closing. Unlimited access. Radar The door is opened by people or vehicles approaching the radar beams. Normally fitted with automatic closing. Unlimited access.
Automatic closing The door is automatically closed after passage by a timer. Safety warning lights Flashing red lights to warn before and during door movement. Traffic lights To increase traffic safety, vehicles can be directed by traffic lights. Reduced opening Sometimes the door does not need to be fully opened to allow passage. Such demand is solved by a reduced opening option. Reduced opening contributes to energy savings since the airflow through the door opening is reduced. Battery back-Up In case of a power supply break-down, a batter operated emergency power function is available. This allows the door to be operated a limited number of times.

1.1 General
1.1.1 Application 1.1.4 Standard T-frame Painting RAL 5010 or RAL 6005 Low noise hydraulic unit Two hydraulic lift cylinders One hydraulic lip cylinder Lip length 500 mm Steel lip The Crawford 625 teledock 100kN is the optimal efficiency solution in general industry and logistics applications. The telescopic lip precisely bridges the gap between the ramp and the lorry bed. The Crawford 625 teledock 100kN system meets the standard demands of most loading operations and fully complies with rules and regulations of the European Standard EN 1398. 1.1.2 Mode of operation Frames connection to building: Surface: Hydraulic Equipment Lip

Options W-frame [frame for welding] Painting RAL 3002 or RAL 9005 Hot galvanised Low temperature oil Bio oil Tapered lip EPDM seal Slip protection/noise reduction
The operation of the Crawford 625 teledock 100kN is based on an electro-hydraulic telescopic lip, controlled by a semiautomatic control unit. When the dock leveller is raised, the lip extends and the leveller lowers gently onto the lorry bed. After loading or unloading, the leveller is raised again, the lip retracts and the platform returns to its parking position, i.e. to ramp level. 1.1.3 Overview
Frames connection to building Surface Hydraulic equipment Lip options Energy & ergonomics

1.2 Telescopic Lip

1.2.1 Lip material

Lip shapes

1.2.2.1 Standard telescopic lip
1.2.1.1 Steel telescopic lip
The steel telescopic lip is designed for use by heavy loading equipment. It has a high durability, while it provides medium comfort.
The standard telescopic lip is a single rectangular lip for use with a fleet of vehicles that is a standard size.
1.2.2.2 Tapered telescopic lip
A tapered telescopic lip ensures that the lip reaches the lorry bed, even when the lorry is not parked in the exact centre position. Avoids damage to the truck and interruptions of the dock-in procedure. s = 100 mm

1.3 Platform

1.3.1 Platform tear-plate thickness

1.4 Surface

1.4.1 Painting
The 10 mm (10/12) tear-plate is designed for loading and unloading with typical 4 wheel pneumatic-tired fork-lift trucks, and is also suitable for handling equipment with high point loads, such as electric pallet trucks. 1.3.2 EPDM seal

1.4.1.1 Colours

The dock leveller standard finish is painted. The standard colours are: RAL 5010 RAL 6005
To seal the gap between leveller and pit, an EPDM seal can be factory-installed between the flexible platform and frame. By reducing draughts into the building, working conditions improve and energy savings increase.
Colours available as option are: RAL 3002 RAL 9005
1.4.1.2 Standard paint class
Slip protection / noise reduction
If the dock leveller is to be used in a rural area, the standard finish is: Paint class 1; 80 m factory painted for corrosive category C2 M

Applying a polyurethane slip protection coating on the lip and platform ensures a durable non-slip and noise reduction surface. The effect is a smooth and comfortable surface for handling equipment that is less receptive to wear and tear. The PU coating material is resistant to impact, to thermal impact and most types of chemicals and it has a high loading capacity.

1.4.1.3 Paint classes

If the dock leveller is to be used in an urban or industrial atmosphere, or in a coastal area, it may be appropriate to select an alternative paint class with increased resistance to corrosion C3 M. Paint class 3; 160 m factory painted for corrosive category C3 M Hot galvanising
To increase corrosion protection to C4 for saline coastal areas or C5-I for aggressive or humid atmospheres, the dock leveller can be delivered with hot dip galvanised (80 m) steel parts.
1.5 Frames - connection to building
The frame is the leveller's connection point to the building and a rigid support for the leveller. The Crawford 625 teledock 100kN is available with different frame types. The frame can be embedded in concrete or installed via screws or welding. All frames are illustrated with the tail lift recess. The levellers are also available without tail lift recess. 1.5.1 T - leveller frame for embedding in concrete
The T-frame is installed in one step. The leveller is directly embedded in concrete.
W - leveller frame for welding
The W-frame is designed to weld the leveller directly to the floor slab. In case of future replacement, the welding points can be ground away.
1.6 Docking control systems
1.6.1 205A Docking control system Hold-to-run button to lift platform. Hold-to-run button to position the lip on the truck bed. Impulse auto button to put the leveller back in parking position. Mains isolator or emergency stop button.

Mains isolator or emergency stop button. 3-digit display for service diagnostics Interface to incorporate Crawford EYE and/or wheel chock. Can be connected to Crawford 101 dock management network.

1.7 Monitoring systems

As an option on all our products, a Crawford Monitoring System can be installed. This system helps to ensure efficiency and security in daily operations. All doors or docking stations are connected to the Monitoring Systems server, which gives the opportunity to supervise, monitor and report a wide variety of aspects in a facility.

Saving energy

A monitoring system reduces energy costs and contributes to a better environment. Energy is lost every time a door is open. If a door is open when no truck is at the bay, even more energy is lost. A Crawford Monitoring System automatically ensures that no door will open unless there is a truck at the bay and even set it to close when there an activity is delayed. 1.7.2 Security enhancement
Closing and locking doors is an obvious daily routine. However, checking this manually can be time consuming in a busy facility. A Crawford Monitoring System can automatically ensure that all doors are closed and locked when they need to be. It can also activate all doors and locks from its remote location, and give a real-time overview of the buildings situation. 1.7.3 Dock management
A Crawford Monitoring System makes visible in real-time which bays are occupied or free, and for how long. It makes it possible to reserve bays for docking activities and to inform drivers via SMS. Since it incorporates information from cameras and other inputs (RFID, card readers, etc.), the system stays updated in real-time. 1.7.4 Facility management
The Crawford Monitoring System gives a real-time service status for all your door and docking equipment. If an error code occurs, the Crawford service organisation is automatically notified, and will respond quickly. Other maintenance information can easily be integrated, further reducing the overall costs.
A good way to increase throughput and thereby efficiency at a logistics facility is to reduce the time of having no truck or the wrong truck at a loading bay.

1.8 Equipment

1.8.1 Buffers
1.8.1.4 RB with steel front and top plate Application
Buffers placed in front of the dock leveller absorb the energy of a vehicle that accidentally or intentionally hits the building. Buffers are available in various sizes, in fixed or moving models, and with rubber finishing or steel plate and spring function.

1.8.1.1 RS Application 1.8.1.5 EBF
The RB buffer with steel protection front and top plate is designed for vehicles with high lorry beds like interchangeable open bodies and containers. Available depths: 90 mm 140 mm
The RS buffer is the economical solution for docking stations where vehicles of equal sizes load and unload.

Application

The EBF buffer is the ideal solution for docking stations where vehicles are expected to make notable vertical suspension changes when loading or unloading. This buffer follows vertical movements of the vehicle. Available depths: 90 mm 140 mm

1.8.1.6 EBH Application

1.8.1.2 RB Application
The RB buffer is a large fixed rubber. It is the universal building and vehicle protection solution. Available depths: 90 mm 140 mm
The EBH buffer is the ideal solution for docking stations where vehicles of notable height differences load and unload. This buffer can be vertically adjusted by a 'release device'. Available depths: 90 mm 140 mm
1.8.1.7 Steel spring buffer 600 Application
1.8.1.3 RB with steel front plate Application
The RB buffer with steel protection front plate increases the building protection and the buffer service life. Available depths: 90 mm 140 mm
The steel spring buffer is the ideal protector of the ramp as well as the vehicle itself.
1.8.1.8 Steel spring buffer 800 Application
Dock light A lorry docked for loading and unloading most likely creates a dark zone which endangers a safe and fast transfer of goods. The dock light ELS is the ideal solution for an optimum of light at the loading bay area and inside the lorry. The wide scattering allows an extensive illumination.
The 800 mm steel spring buffer is designed for applications where vehicles generally are higher than ramp level.
Crawford Eye The Crawford Eye is an electronic, sensor-based dock-in system, that measures the distance between the vehicle and the building. This makes it easier for the driver to complete the dock-in procedure, but also detects objects or people behind the vehicle.
Parking guides This visual aid makes it easier to park the vehicle and reduces the risk of collision. Especially advantageous for docking stations with wide leveller lips and cushion shelters. Parking guides can be bolted or cast in concrete on the floor before the leveller.
Wheel chock The wheel chock has an ultrasonic sensor to detect the presence and position of the vehicle and is connected to the dock leveller control panel. If no vehicle is detected, the docking station is blocked for safety reasons. Furthermore, the wheel chock prevent the vehicle from moving during loading/unloading.
Traffic light The traffic light system has a sensor above the dock leveller that measures the presence of a vehicle. If there is no vehicle (dock leveller is free), the traffic light inside gives red, outside gives green. The traffic light can also be combined with a wheel chock, CrawfordEYE or door/leveller interlocking.

2. Selection guide

2.1 Load capacity according to EN 1398
The EN 1398 describes 3 key definitions about loads. 2.1.1 Rated load
The rated load is the total weight of the goods, the forklift truck and the driver.
2.2 Select the load capacity
The load capacity of a dock leveller must always be higher than the rated load. 2.2.1
Example 6000 kg 3400 kg 100 kg 9500 kg 10000 kg/100kN

Axle load

Axle loads shall be taken acting over two rectangular contact areas at 1 m lateral distance. These areas shall only apply if the actual conditions do not call for more severe loading. The size of the footprint [mm] is derived from the wheel load [N] divided by 2 [N/mm]. The ratio of the rectangular print is W:L = 3:2.
Weight of forklift truck Weight of goods Weight of driver Total weight/rated load Suitable load capacity of the leveller
2.3 Select the platform tear plate thickness
The 10 tonnes (100kN) 625 teledock 100kN is as a standard equipped with a tear plate of 10 mm (10/12).
In the drawing measures for a leveller with a load capacity of 60kN. 2.1.3 Dynamic load
The dynamic load is the movement of the rated load and is the pressure on the leveller platform caused by the moving forklift truck.

Selection guide

2.4 Select the leveller length
When determining the leveller length, measure the maximum height difference between the truck bed and the dock level. Next, determine which vehicles will be used and lookup the maximum gradient the vehicles are allowed to be used on.

Vehicle Max gradient

Roll cage Hand pallet truck Electric pallet truck Forklift truck (battery) Forklift truck (gas / petrol) 2.4.1 The calculation

3% 3% 7% 10% 15%

Minimal leveller length = height difference / gradient (%) 2.4.2 Example Electric pallet truck (max 7% gradient) mm 1150 mm
Vehicle: Truck height: Dock height:
The difference between Truck height and Dock height = 175 mm 175 mm / 7% = 2500 mm leveller length

2.5 Nominal width

The Crawford 625 teledock 100kN is available with a nominal width of 2000 mm or 2200 mm. The correct nominal width must exceed the widest loading vehicle by at least 700 mm.
