First, the system functions

-101series of tower crane safety monitoring system include tower crane collision warning, emergency stop, regional protection of the tower crane, tower crane’s construction environment monitoring and tower crane movement status monitoring, with real-time alarm , stop, black box function.

（1）) collision warning between the tower arms

When the towers are working at the same altitude, their arms might collide with each other(including the jibs and counter jibs), the tower crane safety monitoring system will send alarm signal when their arms are getting too close. It can remind the drivers’ caution, and automatic shut off if the drives did not stop manually.

When the two tower cranes are not working at the same altitude, the lower tower crane’s arm might collide with the higher tower’s mast.

The tower crane safety monitoring system will send alarm signal when lower tower crane tower’s arm getting too close to the higher tower’s mast. It can remind the drivers’ caution, and automatic shut off if the drives did not stop manually.

When the two tower cranes are not working at the same altitude, the lower tower crane’s arm might collide with the higher tower’s hook and rope.

The tower crane safety monitoring system will send alarm signal when lower tower crane tower’s arm getting too close to the higher tower’s hook and rope. It can remind the drivers’ caution, and automatic shut off if the drives did not stop manually.

（1） crane arm region protection

Limiting the crane’s arm to enter certain areas, to prevent the collision between the crane arm and the buildings, telephone poles and other stationary obstacle. As shown below.

Limiting the hook move into certain areas, to prevent the rope, hook and the lifting objects to collide with the buildings, telephone poles and other stationary obstacle.

Monitor the tower crane’s loading capability. Based on the wind speed and the tilt of the tower crane at working site, to prevent the collapse of the tower crane, or hanging heavy objects falling.

Compared with similar products,AS-101 series of tower crane safety monitoring system has the following characteristics:

u The advanced algorithm to ensure sending the alarm signal on time.

u sound and light warning, simple and convenient to get drivers’ attention to the danger, and will not distract drivers’ attention

u Intelligent braking, when sound and light warning invalid, automatic power shut off to avoid the occurrence of high-risk situations

u full-featured set of rotation, range, weight, height, wind speed, several upgrade option.

u centralized management of all data changes and parameter adjustment can be completed in the control room without the need for onsite operations

u focus on observation, the control room have in real-time observation of the tower crane’s operation, the ability to detect the fault

u reliable communication module, long transmitting distance, the strong ability to cross through barriers.

u easy installation and removal, the installation process is not affecting the tower crane operations

u easy to use, the driver does not need to modify any data, to avoid human caused error

l Power Requirements: AC 220V ± 10%

l Operating temperature: -20 to 60 ° C

l Operating Humidity: 0 ~ 95%

The angle sensor install in the tower crane’s slew meshing gear, range sensor install in the trolley’s amplitude limiter linkage axis; height sensor install in the trolley’s height limiter linkage axis; tilt sensor install in the cross beam of the crane arm; wind speed sensor install on the top of the tower crane; weight sensor install in the force of the tower crane fixed pulley. Sensors by connecting the cable access to the anti-collision alarm main board, through the mounting bracket secured to the body of the tower crane machine, sucker antenna and tower crane safety monitoring main  board install in the tower crane cab.

Power cord, signal cable interface are the three core and four core.

In order to ensure reliable operation, installation environment requirements are as follows:

1. Supply voltage should meet the equipment requirements, and properly grounded;

2. Device securely mounted to prevent any part of loss and mechanical damage;

3. Cable should be properly layout, away from the mechanical operation of the institutions, and prevent injury composition

4. The main board should be away from heat, keep the air vents unobstructed

5. The main board is placed in a dry environment.
