Main mechanism details
1. Electrical mechanism
Our company use France Schneider contactor, and tests each hoisting mechanism under no-load, static load, dynamic load, etc. To ensure the brake reliable, safe and durable.
2. Hoist mechanism
Brake wheel adopts cast steel materials, surface quenching and external circular, control the beating degree strictly. At the same time, also carrying on balance tests. Each hoisting mechanism is carrying on no-load, static load, dynamic load and so on, guarantee the reliability, safety and durableness.
3. Derricking mechanism
Derricking mechanism with free maintenance planetary reducer and cone brake motor, is well-knit in structure, stable and powerful in trolley, high endurance and low failure rate.
4. Slewing mechanism
Slewing motor adopts winding motor and hydraulic transmission. Slewing is stable and powering.
5. Operation device
Cabin with humanized design, is convenient and comfortable, facilitate for safe driving.
6. Mast section
Welding process use high-strength wire. Main joints use special steel and special process.
