Single-speed electric wire rope hoist

Structure and operating principle

A conventional wire rope hoist with a single normal lifting speed.

The motor, brake, reduction gearing and drum drive the reeved wire rope and hook block. A trolley, where fitted, supports travel on the designated beam or bridge rails; its compatibility is part of the complete installation.

Application and selection

For vertical lifting of freely suspended loads in compatible workshop lifting systems. Duty, headroom, hook travel, beam geometry and power supply determine the suitable hoist configuration.

Working method

1. Before work, authorised personnel confirm the load and its centre of gravity, the permitted machine configuration, the route and receiving position. Complete the checks specified for the equipment, verify protective functions by the approved method and stop if a defect affects safe operation.

2. Check rope reeving, hook condition, controls and brake response according to the manual. Centre the hook above the load, lift without side pull and use the intended speed control to position and lower it.

3. After the task, place the load on stable supports and leave the equipment in its prescribed safe state. Record faults and abnormal events. Maintenance or jam clearance requires secure isolation of relevant energy, including stored hydraulic, pneumatic and gravitational energy.

Precautions and maintenance

Do not lift people, wrap the hoist rope around a load or run into the upper limit as normal operation. A standard workshop hoist is not automatically suitable for molten metal, explosive atmospheres or cleanroom service.

Inspection frequency, wear/discard criteria, lubrication, brake adjustment and replacement parts follow the supplied instructions and applicable local requirements. Only competent personnel may maintain the equipment; return to service follows the prescribed checks.

Configuration and standards

This is an equipment-selection and operating-principle overview, not a complete operator manual, lift plan or certificate. Verify rated load, duty, geometry, environment and protective functions against the nameplate, approved drawings and delivered instructions. Do not combine separate series maxima into one promised configuration.

Requirements follow the destination and installation, not the website language. China: determine the applicable GB/T references and statutory equipment obligations. EAEU destinations: check the applicable TR CU/EAEU regulations, amendments and conformity documents. English-speaking markets: select the relevant national rules; US OSHA and UK HSE references are not universal law. EU projects require their own applicable conformity assessment.
