Overview
HC Square Box Heavy Duty Electric Hoist
The HC square-box wire rope electric hoist is a professional heavy-lifting solution for large tonnage loads, different from ordinary CD/MD cylindrical light-duty hoists. It adopts a solid square box and planetary reducer, focusing on heavy load work of 16 t and above. It is compatible with double-girder overhead cranes and gantry cranes for frequent heavy-duty operations, while HCM and HM are its dual-speed models with adjustable lifting speed.
The HC hoist is designed for altitudes up to 1000 m, ambient temperatures from -25°C to +40°C and relative humidity up to 85% (at +25°C) with no corrosive gas, on a 380 V, 50 Hz supply. It is not suitable for lifting high-temperature, toxic, flammable or explosive loads. Lifting heights run from 9 m to 48 m, and the hoist is supplied in travelling and fixed versions.
Key features
-
01
Heavy-duty square planetary reducer structure with M3–M6 working class, which withstands long-term, frequent heavy-load lifting far better than ordinary cylindrical hoists.
-
02
Compact low-headroom design with fully sealed housing and good dust and moisture resistance, suited to limited-height factories and harsh industrial environments.
-
03
Complete safety protection, including motor overheat protection, upper and lower limit switches and an optional overload limiter.
-
04
Modular split structure for easy maintenance; available as single-speed HC and dual-speed HCM/HM models with custom options (explosion-proof, wireless remote, variable frequency).
Where it is used
- Heavy Machinery & Steel Structure Workshop Large steel component lifting, mold turnover, heavy workpiece assembly and long-cycle material transportation for heavy manufacturing factories.
- Construction & Large-scale Engineering Steel frame erection, heavy equipment hoisting, bridge component installation and heavy material handling at construction sites.
- Metallurgy & Heavy Processing Heavy workpiece transfer in steel mills and continuous, frequent heavy lifting in metal processing workshops (not for high-temperature loads).
- Port & Logistics Yard Heavy container parts loading/unloading, bulky cargo stacking and cross-region heavy goods turnover at freight terminals.
- Mining & Energy Industry Heavy equipment handling at mine sites, wind power large parts installation and maintenance, photovoltaic heavy bracket mounting.
- Heavy-duty Crane Supporting Perfect matching double-girder overhead cranes and gantry cranes for 16t+ high-frequency intensive heavy lifting operations.
