Double Girder Hoist Crane

The advantages of the lifting mechanism are as follows:

• Compact design optimizes crane work space

• Low vibration, quiet running motor

• Quick response brakes

• The gearbox is fully lubricated and does not require refueling

• Specially designed rope guide protection wire rope (exclusive to Xiongfeng)

• Precise hoisting mechanism limit

• Overload protection

• User-friendly hook pulley design

• Frequent motor protection: In the control system, the program automatically detects the customer's jogging. The time interval between two jog attempts is approximately 0.5 seconds. If the jog occurs too frequently, the system automatically extends the jog interval to approximately 2 seconds. To protect the motor and avoid burning the motor.

The advantages are as follows:

• Squirrel-cage asynchronous motor (synchronous speed reaches 3000 rpm).

• Two-speed or variable frequency stepless speed regulation.

• Heavy duty with a duty cycle of 60% ED.

• Electric disk brakes, self-adjusting brake pads, wear self-compensation, alarm when the thickness of the brake pads is not enough.

• Normally closed brake and motor integrated design, good synchronism, and at least 1.8 times the safe braking torque to effectively prevent the hook

• Sealed and dustproof.

• Heavyweight.

• Large friction contact area and adjustable braking torque.

• Non-asbestos friction plates, environmentally friendly.

• Brake pad life: no less than 1 million normal use and no less than 500 emergency brakes.
