7.5 Ton Single Girder Electric Wire Rope Hoist- DIMENSIONS(MM)

1. Hoisting Motor: Reserved for squirrel-cage inductor motor and the outer casting are made of gray cast iron. Hoisting motor is classified as 30% ED with 180 times/hour switch frequency. (60% ED is optional.)

2. Gear Box: Small size of all-planetary deceleration gears can run with a larger torque and low noise.

3. Wheel: Turning from S45C material, heat-treated surface, bearing high pressure and good abrasive resistance.

4. Wire Rope: The rope has at least 5 times safety factor, high tensional strength, wear-proof flexible steel can endure bending fatigue.

5. Up and Upper Limited Switch: When the hook touched the emergency limit switch, it cuts off main power supply immediately.

6. Brake System: DC electromagnetic brake disc have faster reaction and 150% braking force.

7. Eccentric Shaft: Auto- adjustment (patent no. 40602), can run on uneven and still sustain the load evenly.

8. Control System: Electromagnetic switch includes the mechanical linkage: coil includes surge protector.

9. Drum: 16 times greater than the diameter of wire rope. It meets to the safety standard of fixed crane.

10. Sheave: Made of gray iron casting. It is 18 times the diameter of wire rope.

11. Push-Button Switch: Reinforce plastic shell, one piece design, good insulation is able to endure the impact and resist fire. Control cable includes high- strength steel wire to strengthen the security of suspension.

12. Hook Assembly: Forged and heat-treated by alloy steel with high strength, high resistance against wear. It is with thrust bearing enabling hook to swivel 360 degrees and 4 times safety factor with safety latch to ensure operational security.
