HC Square Box Heavy Duty Electric Hoist

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 16t and above heavy load work. Compatible with double-girder overhead cranes and gantry cranes for frequent heavy-duty operations, while HCM and HM represent its dual-speed models with adjustable lifting speed.

  • Heavy-duty square planetary reducer structure, M3-M6 high working class, withstand long-term frequent heavy load lifting far better than ordinary cylindrical hoists.
  • Compact low-headroom design with fully sealed housing, great dust & moisture resistance, ideal for limited-height factories and harsh industrial environments.
  • Complete multi-safety protection system including overheat motor, upper/lower limit switches and optional overload limiter to eliminate lifting risks.
  • Modular split structure for easy maintenance; available in single-speed HC & dual-speed HCM/HM models with full custom options (explosion-proof, wireless remote, variable frequency).

5. Type: can be divided into running type and fixed type.

Widespread Application Scenarios

Thanks to heavy-duty square box planetary reducer, high M3-M6 working level and multiple customized specifications including low-headroom, explosion-proof and low-temperature resistant types, our HC heavy-duty wire rope electric hoists are widely applicable to various heavy industrial fields:
  • 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: High-temperature heavy workpiece transfer in steel mills, continuous frequent heavy lifting for metal processing workshops.
  • Port & Logistics Yard: Heavy container parts loading/unloading, bulky cargo stacking and cross-region heavy goods turnover at freight terminals.
  • Mining & Energy Industry: Mine underground heavy equipment handling, 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.
