The Crawford 640 drawbridge DMW is installed in a fix position, and the Crawford 641 drawbridge DMGZ is installed in a guidance rails placed in the front edge of the ramp. The latter alternative makes it possible for the leveller to operate in different ramp positions.

Model DMW
It is fixed in position by welding it to a cast-in channel on the dock wall.

Model DMGZ
It is installed on bearings in a guide rail (supplied separately) which must in turn be fixed in position by welding to a cast-in steel channel on the dock wall. It can then be finitely positioned by sliding it along the rail.

Both versions are steel constructions equipped with a heavy-duty spring device, enabling it to be conveniently lifted and lowered by hand. They incorporates the most recent developments in our proven range of drawbridge levellers. They are equally suited for internal or external applications. With all steel parts being hot galvanised these models are very durable and ideally suited for applications where hygiene is paramount. They are operated manually by releasing the lock on the handle(s) and lowering the platform onto the vehicle bed. The counter balance springs assist with reducing the weight when manually positioning the levellers, and allow them to adjust to varying vehicle heights during the loading/unloading operation. The aluminium alloy lip is segmented, which ensures they can accommodate a lateral deflection across the width of the docked vehicle. When not in use they can be padlocked to prevent unauthorised use. The new features of these dock levellers ensure that they comply with the new European EN 1398 standard.

The lip is a segmented aluminium alloy lip, compensating for sloping vehicle beds and facilitating smooth passages.

Model PG
The Crawford 643 Drawbridge PG is the alternative aluminium alloy model which completes this part of the leveller's programme. It covers the needs for less load capacity and less working range, and this light version can also easily be handled by one person. It is principally designed for external applications. A special guide rail is welded to the dock edge along which the PG can be moved and then raised or lowered using the operating rod, onto the vehicle bed above or below dock level. When not in use, the PG stands upright in the guide rail, secured by a pawl. All dock leveller and plates comply with the European EN 1398 standard for loading equipment.

Mobile dock plates
The Crawford mobile dock plates are the universal solution for all loading situations. In spite of their mobility, they are capable of handling heavy loads due to the special aluminium alloy material. Mobile plates can be used as a permanent loading solution or as an additional, back up capacity in case of unforeseen ramp bottlenecks. Automatic locking arms, safety hooks and full-depth lip heels give safe dock plate contact with the vehicle.

Loading railway cars
For loading and unloading of railway cars, the railroad operators have issued a number of rules that must be taken into consideration. Two Crawford solutions are available: sliding or rolling dock plates. Both are made of a special, high performance aluminium alloy and meet all loading requirements and safety regulations for railway car loading.
