| Combilok®, developed by and exclusive to Stertil Stokvis, is a vehicle restraint system providing enhanced safety at loading bays whilst loading and unloading is in progress.
Communication between the vehicle driver and the loading personnel in such situations is usually poor, leading to the risk of accidents if the vehicle were to drive away when loading / unloading is in progress.
The Combilok® helps to prevent the vehicle from driving away until it is positively released by an operative within the loading bay.

DESCRIPTION
Steel construction with galvanised finish.
Hydraulically powered.
Optional high-visibility yellow powder coating.
OPERATION
When the vehicle is in position, the operator activates the Combilok® system from a control panel inside the loading bay.
The wheel block moves forward, powered by a hydraulic ram.
A built-in sensor automatically stops the blocking arm in the correct position in front of the vehicle's rearmost wheel. It then extends in front of the wheel and is pushed back against it at a constant pressure.
The Combilok® is then in position to help prevent unexpected vehicle movement until released.
Warning signals
The movement / operation of the wheel blocking arm is indicated by both an audible signal and a warning red traffic light.
When the Combilok® is removed a green traffic light indicates to the driver that the vehicle is safe to leave.
A warning light on the control panel shows the operator when the restraint is in place and when released.
