Vehicle Restraint Systems
C-Mech is the UK Distributor for the Calematic Automatic Wheel Chock System, which has been in use throughout Europe since 1989. Its purpose is to automatically restrain vehicles backed on to a Loading bay whilst a Dock Leveller is being used when loading or unloading. This prevents trailer units being taken off the dock before it is safe to do so (drive away), and negates potential problems due to trailer creep (see explanation of trailer creep at the bottom of this page). There are many different methods of Vehicle Restraint of varying complexity and cost, but Calematic has various unique features and many examples of maintenance and damage free usage over a number of years. Clients include Cummins, Ardo, L’Oreal, Bayer, Bosch, Iveco, Ford, Firestone, Astra Zenica, 3M, Nestle, Pfizer, Renault, UPM, Monsanto, and Michelin.
- Completely flush with yard floor when stowed away, so very difficult to damage and ideal when there is restricted room for vehicles turning to reverse on to a Loading Bay.
- Keeps operatives out of potentially hazardous yard area as system is fully automated and triggered by opening & closing the Loading Bay Door.
- Designed to be maintenance free and unaffected by typical Loading Bay debris.
- Unaffected by snow or ice and will even operate when submerged.
- Simple construction with only 5 mechanical parts per chock and no complicated sensors or control system. NO motors, bearings, chains, gears, hydraulics or grease.
Operated by low pressure compressed air so eliminates potential Health & Safety or Environmental hazards associated with electrical or hydraulic operation respectively.
- Zero trip hazards as there are no surface mounted parts between adjacent vehicles when in use, and completely flush with floor level when not in use.
TRAILER CREEP - This occurs when the lateral and vertical forces exerted each time a lift truck enters and exits a trailer cause the trailer to slowly move away from the dock resulting in separation from the dock leveler. Factors that affect trailer creep are:
- Weight and speed of the lift trucks and their load
- The surface of the yard the trailer is parked on
- Softness of the suspension
- Type of dock levelers
- If the trailer has been dropped off or still connected to the tractor unit
