- Mini bar refining crane product introduction
1) The electric crane adopts:
Two brake systems: (1) motor brake (2) mechanical load-bearing brake
Four sets of safety devices: (1) motor overload protection (2) electric limit switch (3) emergency stop (4) overload sliding clutch
2) Durable aluminum alloy body structure, providing lightweight, simple and short suspension distance
3) Adopting high tensile alloy steel to carry the refining strip, hot-dip galvanized treatment and wear-resistant.
4) All gears and pinion shafts are made of high-quality alloy steel with excellent surface hardness, and are supported by anti-wear ball bearings at both ends. The gears operate in sealed oil grooves.
- Purpose:
