> Dock Levellers
An elyctro-hydraulic dock-leveller is not simply ''a bridge for connecting a vehicle”. Frequently the important characteristics that this tool needs are undervalued, in order to guarantee an efficient working environment to comply with the safely in work regulations. Since the invention of the hydraulic dock-leveller, very poor design improvement has been implemented by manufacturers of the traditional hypes, (and the result is old concept products with poor characteristics in respect of safety in work and installation. BFJ dock-levellers have been manufactured since 1 975. In 1983 a completely different concept was applied to satisfy different customer needs, offering new advantages and often cheaper costs. The most advanced concept of the BFJ dock-leveller is to have the whole drive unit contained in (a wall box which is installed on (a wall inside the warehouse, at eye level, which allows for easy and economical maintenance, without the necessity to maneuver under the platform or inside the pit, where traditional powerpacks and controls are usually installed: an undoubtedly dangerous, dirty (and uncomfortable operation.

A wide study of previously installed power units motivated us to design the MULTIPLE CONSOLLE. Depending on the type of installation it can hydraulically power several dock-levellers with only one CONSOLLE (drive unit), each clock-leveller controlled separately by its own control pad. They can also work simultaneously. With these solutions we have dramatically economized by optimizing the function of the single parts so successfully that we have practically eliminated, for several years, any repair intervention. Further dramatic economies are obtained by reducing the electric mains supply points to one per CONSOLLE instead of one per dock-leveller. The reduction is about 65% in dock-leveller installations and about 75% in dock-leveller and powered sectional door installations. This reduction normally result in important economies when installing the mains distribution box. Consequently by reducing the number of motors there is a dramatic saving on electricity costs, as the global mains power engagement is radically reduced.

When choosing the dock-leveller, remember that the Laws and Norms of safety in work clearly show how a dock leveller has to be dimensioned. They particularly demand a dock-leveller as wide as the truckbed, to enable loading-unloading of the last right and left pallets with the wheel of the fork-lift truck maintaining a minumum of 350 mm from the edge of the dock-leveller. The most common choices are widths of 2200 mm and 2400 mm, both with side flaps. Norms of safety in work clearly state that the dock-leveller's slope must not exceed 10%. Vehicles no longer lower so much under load with todays pneumatic suspensions, thus lenth of 2500 or 3000 plus lip is normally sufficient. For new buildings keep the dock lower: it is always much better to have the vehicle truckbed 100 mm-150 mm higher than the dock.

The BFJ dock-leveller is supplied complete with:

  • Platform and lip in chequered anti-slip steel
  • Single effect lift cylinder, double effect lip cylinder
  • Safety stop in case of accidental departure of the vehicle (the platforms stop in about 20 mm)
  • Maximum pressure valve
  • Side foot protection steel sheets-installation kit
  • Rubber bufferse 300 mm X 55 mm X 60mm
  • Wall CONSOLE containing the whole drive unit and control, with low level conduit protection
