Overview

Rope drum/rope drive

• Large drum diameter with
improved space utilization
• Low wear on ropes and
return sheaves
• Minimum hook travel:
Also due to limited inclined
pull, loads can be moved and
positioned safely and precisely
• Easy access to the upper return
sheaves and anchorage points
• Rope drum encapsulated as
standard with powder-coated
metal surfaces

Rope guide

 Configured to meet
specific application needs

A variety of options are available to equip DVR rope hoists

to meet given application requirements.

DVR units can offer variable-speed drive solutions for Load-dependent lifting speed for higher productivity:
lifting and travel motions at different technology levels. • High speed without load (up to 100%)
The benefits of their inverters are self-evident: • Medium speed with partial load
• Variable speeds: 1:10, 1:25, ESR 1:37 • Precise speed with full load
• Reduced wear: Gentle start-up/lifting reduces the load
on the crane system
• Longer motor/brake service life
• Significant energy savings by up to 50%
