Laterally sliding drawbridge leveller

The PKBS laterally sliding drawbridge leveller manufactured by PROMStahl is designed for bridging loading areas with small or medium differences in height and may be operated by one person. This leveller slides laterally and is stored vertically at the edge of the dock when not in use; its load capacity is 40 kN; the maximum difference in height that can be compensated for amounts to 135 mm.

This type of drawbridge leveller is made of durable weatherproof aluminium alloy and meets the highest requirements of modern goods traffic. The automatic lock/release system prevents accidental fall-down of the device.
