| DESCRIPTION
Parallelogram lip
The Stertil Stokvis P Series has a hinged lip which is activated by a unique parallelogram linkage. This extends the lip automatically as the platform deploys, and maintains the lip horizontal at all positions of the platform.
Ergonomic design
The P series ergonomic dock leveller offers many advantages including substantial cost savings on maintenance of material handling equipment and less personnel absence due to lower impact on human body. Loading and unloading is faster and smoother, noise levels are lower and there is less damage to goods.
Rear platform hinge
The rear platform hinge is bedded on polyurethane strips to reduce impact and noise, whilst allowing up to 100mm platform tilt at the front edge.
Choice of platform finish
Standard finish is Treadplate.
P Series dock levellers are available with an optional Twaron polyurethane anti-slip coating to platform and lip. This gives smoother running and can reduce noise levels by up to 10dB, especially beneficial where small-wheeled pallet movers and roll cages are mainly used.
Control, operation
Control is by a single push button.
When the button is pressed the platform rises to its highest position and the lip extends into place automatically. When the button is released the platform lowers until the lip rests on the vehicle floor, the lip remaining horizontal at all times.
When loading/unloading is completed, pushing the button again returns the platform and lip automatically to the parked position.

LOADING
Load rating is 6000kg for all models and sizes.
This is the total maximum load capacity as defined by EN1398 which may be carried on a single axle.
DIMENSIONS
Lip
Standard lip length is 400mm.
Platform
Selection of dock leveller platform length depends primarily on the expected range of vehicle floor heights compared with the dock floor level, taking into account the maximum possible incline of the platform.
The maximum incline permitted by the EC/EN 1398 standard is 12.5% (7° or 1:8), but in practice Stertil Stokvis sizes are based on a lower incline since this allows smoother and running and a shallower incline for loading.
We recommend consultation with Stertil Stokvis at an early stage in dock planning for guidance on selection of the correct size.
