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 rotation, amplitude and operation area of the tower crane to avoid collisions between the mechanism, lifting rope, or lifting weight of the tower crane.
What are the differences in the installation of Tower cranes in different structural forms?
There are many kinds of structure forms of Tower cranes, so various types of installation procedures are also different. What are the differences in the installation of Tower cranes in different structural forms
1. Small car variable amplitude self-rising tower crane
After installing the tower body and the overhead sleeve, install the tower cap(including the rotary support and the high and low rotary support), and then separate and install the balanced arm Heqi heavy arm.
2. Arm self-lifting tower crane:
The movable arm type self-rising tower has a small radius of rotation at the tail of the crane, and some of them integrate the balance arm with the rotary support, forming a rotary platform that is easy to install.
The moving arm is lifted with a lifting device to connect the arm root with the turntable. It can be pulled up by its own variable-amplitude hoist after the pulley set of the variable-wound wire rope.

3. Flat head tower hanging:
One is that the lifting arm and the balancing arm are all fixed to the tower head, and the other is to hinge the equilibrium arm and the rotary support seat, and then use the pull rod to connect the balance arm and the tower head.
When the device is carried out, the balance arm and the lifting arm are resolved and decomposed alternately, that is, a section of the balance arm is installed, a section of the weight arm is installed, and then a section of the balance arm is installed, and a section of the weight arm is installed., and so on.
To reduce the inequilibrium torque of the forward and backward tilting of the tower crane.
