Recently, many friends have been asking about how to install tower crane monitoring systems and how to power them. This topic has been frequently discussed in the weak current VIP technical group, so let’s explore it together in this issue.
1. Networking for Tower Crane Monitoring
Setting up a tower crane is not difficult; it mainly requires two components: a monitoring camera and a wireless bridge.
Connect the monitoring camera to the wireless bridge using an Ethernet cable. The power can be sourced from the control room of the tower crane, allowing the monitoring video to be transmitted directly from the tower crane to the monitoring center on the construction site.
If video sharing is needed, the monitoring center can share the monitoring video over the internet, allowing relevant personnel to view it online and even control the on-site monitoring cameras through a remote monitoring platform.
The schematic diagram is as follows:
2. How to Install Tower Crane Monitoring?
1. Before ascending the tower crane, construction personnel must wear safety helmets, safety belts, gloves, and soft-soled non-slip shoes. Clothing should be flexible, with sleeves and pant legs secured.
2. It is strictly prohibited to carry tools, equipment, and materials while climbing the tower crane. Tools, equipment, and materials should be coordinated with the site manager to be lifted to the tower crane platform by the crane operator.
3. Upon reaching the tower crane platform, the other end of the safety belt must be secured to the inner guardrail of the tower crane.
4. The PTZ camera is generally installed on the side facing the construction site. The PTZ arm is fixed by tightening steel ties through the upper two holes onto the horizontal bar of the guardrail, and a 10CM long guide rail is added below, with the arm secured to the guide rail using wire.
5. The installation of the equipment box is shown in the figure below:
6. Wiring process. The power line for the PTZ camera and the 220V power supply line must be encased in corrugated tubing, and then tied along the railing with zip ties or wire. The wiring should be “horizontal and vertical, neat and tidy,” with zip tie spacing evenly distributed and not exceeding 15CM.
7. Wiring. Connect the 220V mains power to the automatic reclosing device, and plug in the power supply for the PTZ camera.
The power lines for the PTZ camera are shown in the figure below: connect the red and black power wires of the PTZ camera to the two wires of the 24V power supply, and wrap the connections with electrical tape, placing the joints inside the corrugated tubing, hiding all wire ends of the PTZ camera inside the arm.
8. Power sourcing. Generally, the lower platform of the tower crane has a control box for lighting, and the power supply line can be connected to one of the fuses. Before connecting power, use a multimeter or voltage tester to check the power point. Note: Do not connect to the downstream of the time control switch.
If there is no lighting control box on the lower level of the tower crane, power can also be sourced from the distribution box in the tower crane’s control room.
