The range of hoists ensures maximum safety for lifting capacities from 2,000 kg to 20,000 kg.
The range of winches covers capacities from 500 kg up to 200,000 kg.
The WRH wire rope hoist is designed and manufactured in compliance with the Machinery Directive 2006/42/EC and (EU) 2023/1230, as well as the ATEX Directive 2014/34/EU.
IECEx versions, EAC certification and Norsok compliance are also available.
Hoists and winches are suitable for use in potentially explosive atmospheres, with EEx-d & EEx-d(e) protection for Zones 1 and 2, groups 2G and 3G, for Gas (IIA, IIB, IIC) and Dust (Zone 22), and temperature classes T3, T4 and T5.
The three-phase asynchronous motor, with protection rating IP55 (also available in IP66), insulation class F and temperature rise class B, ensures maximum performance within the respective duty classes.
