All motors are F class insulator motor of domestic first class manufacturer(such as Ta Tung, Teco......etc), single speed hoist (or dual speed fast speed )motor, and 40% ED motor exclusive for hoist. possess high start torque, low start current and thermal resistance. |
|
The dual speed cranes are operated by high and low speed motor separately, control the lifting speed by using the clutch, the advantages is one motor can continue the lifting work in case of one of the motor break down. |
|
The winch brake device is solenoid type auto adjustment method, when the braking is worn out, the gap can be adjusted automatically to prevent slipping cause due to wearing. |
|
The brake torque value of the winch brake is 1.5 time of the max., torque value required by rated lifting load. |
|
The travel motor use disc DC solenoid brake device, the brake torque can be adjusted form the external of the brake, high performance and easy maintenance. |
|
The steel rope is exclusive of steel rope for crane with more than 5 times of safety factor. | |
The hook is carbon steel forged, 5 times or more in safety factor, with safety device to prevent the loosen of the lifting steel rope. |
|
The gear box is lubricated by grease, save the trouble in topping up the motor oil and no concern of pollution. |
|
The gear material SNCM220 carburizing heat treated with more than 60HRC, the gear wheel material S45C is high frequency surface treated, with more than 50HRC. |
|
Over-winding prevention device, the crane use two stages upper limit protection equipment, the first stage control cut off the power supply, the second control the cuts off power supply to motor, possess double protection. |
