| DESCRIPTION
Swing lip
Stertil Stokvis S Series dock levellers have a hinged lip which is automatically activated by a second hydraulic ram.
Control, operation
Control is by a single push button.
When the button is pressed the platform rises to its highest position and the lip is extended into place automatically. When the button is released the platform then lowers until the lip rests on the vehicle floor.
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. Options 450mm, 500mm.
Crown angle is 7.5° as standard. Option of 5° for improved transition of materials handling equipment with low ground clearance..
Dock levellers over 2000mm wide have a lip tapered in width to allow better access to offcentre vehicles.
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 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.
