Recently, a friend has been asking about weak electric Jun,
Tower Crane monitoring related knowledge, how to install a camera on the tower crane? This issue has been discussed many times in the weak VIP technology group, so let's take a look at this issue.
First, the construction workers must wear safety helmets, safety belts, gloves before wearing the tower crane, wear soft non-slip shoes, the clothes need to be flexible, and the sleeves and trousers should be tight.
Second, it is strictly forbidden to carry tools, equipment and materials to climb tower cranes. Tools, equipment and materials should be found in the relevant person in charge of the construction site to coordinate the tower crane driver to help hoist the tower crane platform.
3. After reaching the tower crane platform, first fix the other end of the seat belt on the inner guard bar of the tower crane.
4. The ball machine is generally installed on the side facing the construction site. The cross arm of the ball machine is fixed: the upper two holes are fastened to the crossbar of the guardrail by the steel cable ties, and a 10CM long guide rail is attached at the bottom, and then The wire secures the cross arm to the rail.
Fifth, the installation of the equipment box, as shown below:
Sixth, the circuit deployment process. The ball machine power cord and the 220V power cord must be sheathed, and then tied with a cable tie or wire along the railing. The line should be “horizontal and verticalâ€, and the cable tie should be evenly spaced and should not exceed 15CM.
Seven, wiring. The 220V mains access is automatically re-closed to the pile, and the power plug of the ball machine is inserted.
The power cord of the ball machine is as shown below: the two power cables of the red and black of the ball are docked with the two wires of the 24V power supply, and wrapped with electrician glue. The joint is sleeved in the bellows, and all the wires of the ball are hidden in the cross arm.
Eight, take power. Generally, the lower platform of the tower crane has a control box for the lighting, and the wire can be connected to the lower pile of one of the fuses. Before the power is connected, the power point should be tested with a multimeter or an electric pen. Note: Do not receive the subordinate switch subordinate.
When there is no lighting control box in the lower layer of the tower crane, it is also possible to take power in the power distribution box of the operating room of the tower crane.
Suspended Platform
Suspended platform, as temporary suspended cradle platform, are
widely applied in maintenance applications such as curtain fecade
cleaning in high rise building, painting, glazing repairs, bill- board
painting, cable installation and other outer working of high rise
building up to 150 meters about 30 floors high. Our ZLP series suspended
platform cradle, ZLP1000, ZLP800, ZLP630, ZLP500, ZLP400 and ZLP150, are
good choices for fulfill above outside of wall work. Based on the different materials, the suspended platform could be divided into Aluminum Working Platform, steel Working Platform, galvanized Working Platform.
ZLP series temporarily installed suspended platform is an ideal access equipment for building facade construction, decoration, cleaning and maintenance. It can be also applied to other aerial working such as elevator installing, ship building, construction of dam, bridge, large chimney, etc.
This equipment is easy to operate, convenient to move and reliable in safety and much more efficient than traditional scaffolding.
