Raw material
Raw material is the base of the product and the most important wayensuring the quality. We buy the raw material from steel factory like Baosteelor Wisco.
Electrical mechanism
Use French Schneider contactor, broken phaseand phase sequence protection and protection for overload
Hoisting mechanism
Brake wheel use cast steel materials, surface quenching andexternal circular, control the beating degree strictly. We have balance test,each hoisting mechanism has the no-load, static load, dynamic load test to makesure the perfect work performance.
Derricking mechanism
Derricking mechanism with free maintenance planetary reducer andcone brake motor is compact and reasonable in structure, stable and powerful introlley, high endurance and low failure rate.
Slewing mechanism
Slewing motor use winding motor and hydraulic transmission,slewing is stable and powerful
Safety protection
Weight limiters use the pull-ring structure, force moment adoptbow-board mechanical type which suitable for the bad wild environment, and alsoensure the limiter sensitive and reliable, avoid accidents because ofnonstandard operation.
