Tower Crane Knowledge sharing:

Special scheme for tower crane installation safety: installation requirements, preparation, jacking and operation

2. Operation of various institutions

When the air switch has been closed and the various agencies are ready to be operated, the left and right operating handles must be placed at the zero position first, and then the starting button is pressed to make the main contactor suction.

The power indicator is on, and the tower crane is in the working state to be ordered. Operation, can operate a single agency, but also can operate several agencies at the same time, depending on the need.

3. Lifting mechanism

In the lifting mechanism, the brake is normally closed. When the power is on, the brake opens and when the power is off, the brake closes. During operation, handle should be operated step by step to implement lifting control.

After the running speed of the former gear tends to be stable, switch to the adjacent gear, so as to make the lifting as smooth as possible and reduce impact.

When running in the opposite direction, the operating handle must be moved back to the zero position step by step warning it is strictly prohibited to suddenly move in the opposite direction during running.

The continuous running time of gear I shall not exceed 2 minutes per minute]. After the mechanism slows down and stops, it runs in reverse. The relationship between speed and lifting weight of each gear is shown in the table:

4. Turning mechanism and safety limit mechanism

The rotary mechanism motor is a two-speed motor. In operation, if the handle is still sliding at a relatively fast speed when the handle is back to zero due to inertia or downwind influence, it can be stopped by reverse gear braking, but it is only limited to one gear .

Reverse gear braking in other gears is strictly prohibited. The rotating mechanism is equipped with disc brake, which is only used for fixing the arm of tower crane when working in windy state. Parking with brakes is strictly prohibited.
