LVF Hoisting Mechanism Specifications for Tower Crane
This page provides detailed technical specifications of LVF hoisting mechanisms used in tower cranes. It includes full model coverage, performance parameters and key technical features for selection and comparison.
LVF Hoisting Mechanism Structure
LVF series hoisting mechanism adopts a modular design, combining VFD motor, NGW reducer and rope drum. The structure is compact, stable and suitable for tower crane lifting applications.
- VFD motor with wide speed range
- NGW planetary gearbox with hardened gears
- Lebus groove drum for stable rope arrangement
- Electromagnetic brake system
- Optional safety brake and intelligent control
Technical Range
Based on the LVF series design, the hoisting mechanism covers a wide performance range:
- Lifting capacity: 6T – 64T (tower crane typical range)
- Single line pull: 15kN – 160kN
- Motor power: 22kW – 170kW
- Hoisting speed: 80 – 229 m/min
- Rope capacity: 400m – 945m
Model Description
Example: 22LVF15A
