Polygrabbe (orange peel grabs)
BSV electro-hydraulic polygrabs are designed for use in Waste-to-Energy Plants (WTE) handling municipal waste, wood chip and similar materials.
The standard range of grabs are available in volumes from 325 to 12.000 litres.
These grabs are fitted with 5, 6 or 7 jaws, depending upon grab volume and the materials to be handled. They are available in open, half-open and closed design.
On standard models a solenoid directional valve ensures the grabs opens and closes quickly and smoothly. If required, grabs can be modified to operate by means of reversed motor rotation.
BSV polygrabs offer a choice of automatic or manual operation. For maximum strength and reliability, BSV electro-hydraulic grabs are manufactured of HSLA steel and are fi tted with top quality, proven hydraulic components. All BSV grabs are equipped as standard with the following:
  • Complete hydraulic system (including oil, pump and valves)
  • Multiple plug electrical connection
  • Electric motor IP 55 (3 x 400 V, 50 Hz)
  • Tilt switch
  • Oil temperature switch
  • Oil level switch
Standard models can be modifi ed to suit specifi c applications and individual customer requirements. In addition to polygrabs, BSV also supply specialised attachments for handling straw bales and a range of bucket grabs for transporting bulk materials such as coal, sugar ice, wood chip, salt and similar.
