Taking QTZ63 tower crane as an example, the debugging method of the moment limiter is introduced.
Do not remove or change at will. Below, take the example of the lifting moment limiter applied on the QTZ63 tower crane to explain the debugging method of the torque limiter.
1. When the hook is empty, use a screwdriver to distinguish between the stroke switches 1, 2, and 3 to ensure that the three switches are sensitive and reliable.
1 The stroke switch 1 is a limit switch with a fixed torque of 80 %, press the switch, and the buzzer alarm on the linkage table. Trip switches 2 and 3 are the limit switches for extra torque. Press down the switch.

The power supply for the lifting mechanism to pick up and change the amplitude mechanism is blocked. The lifting hook can only land, and the variable car can only run backwards. And the linkage table instigates the light to shine, beeping continuously alarm.
2. When adjusting the hook takes a fourfold rate and a single breaking height of 40 meters or less, lifting the weight slightly from the ground, the car may run.
3. When the working range is 50 meters long, the car runs to a 25-meter range, and the lifting component is 2290KG. After the lifting weight is lifted from the tower, the adjustment and adjustment of the adjustment screw 4 to the stroke switch 1 corresponds to the stroke switch 1. Change the connection and tighten the corresponding adjustment nut 7.
4. According to the constant amplitude variable code adjustment moment limiter, adjust the stroke switch 2.
5. Adjust the moment limiter to adjust the stroke switch 3 according to the constant amplitude variation.

Features and functions of alarm and display recording device for tower crane
There will be the same slogan on the construction site: safe production. It can be seen that safety is the first place in development and construction. Tower crane as an indispensable mechanical equipment in the construction industry, playing a huge role.

At the same time, its huge body also makes it dangerous, and if an accident occurs, it is a huge disaster. Therefore, the safety device of the tower crane is indispensable. In this paper, the following analysis is made on the characteristics and functions of the alarm and display recording device of the tower crane.
1. Alarm installation:
It is used to actively send acoustic and optical alarm information to the tower crane driver when the tower crane load reaches the assigned value. The device should be able to issue intermittent acoustic and optical alarms to the driver when the tower crane reaches an additional lifting torque or a rated lifting component of more than 90 %.

When the tower crane reaches a rated lifting moment or a rated lifting weight of more than 100 %, the device should be able to issue a continuous clear acoustic and optical warning, and the alarm ability can only be stagnant if it can be reduced to 100 % of the rated work.

2. Display recording device:
Used to display the current main working parameters and rated capability parameters of the tower crane to the driver in a graphical or character manner. The tower lifting device has a display recording device.

Important working parameters include at least the current working range, lifting weight and lifting torque. The rated capacity parameter includes at least the amplitude and the corresponding rated starting weight and rated lifting torque.
3. Anemometer:
Used to issue wind speed warnings and prompt the tower crane driver to adopt precautionary measures in a timely manner. A crane with a height of more than 50M shall be equipped with a anemometer. When the wind speed is greater than the allowable wind speed, it should be able to issue an alarm for the end of the homework.
4. Work space damper:
The tower crane can be equipped with a workspace limiter. For a single tower crane, the working space limiter shall not allow the lifting of the tower crane to enter certain specific areas or after entering the area when it is malformed.

For group towers, the limiter shall also limit the swing, amplitude and operating area of the tower crane to avoid collisions between the mechanism, lifting rope or lifting weight of the tower crane
