Tower crane safety device
Tower crane safety device
What are the tower crane stop maintenance devices? What is the function of tower crane stop maintenance device? Most construction units will use the same slogan, that is, safe production, so the name thought meaning, development and construction safety is the premise. Tower crane is a large mechanical equipment, of course, its safety should not be overlooked. In addition to strengthening the technical level of personnel operation, but also to strengthen the tower crane maintenance equipment. So, what are the tower crane stop maintenance devices? What is the function of tower crane stop maintenance device?
1. Cable breaking shield for trolley
It is used to prevent the car from losing control due to the breaking of the traction rope. For the trolley luffing tower crane, a two-way trolley luffing rope breaking protection device should be set to prevent the trolley from losing control due to the breaking of the trolley's traction rope.
2. Anti-tripping device of tower crane wire rope
It is used to prevent the steel wire rope, such as pulley, hoisting drum and swing arm winding drum, from detaching from the pulley or drum. The lifting drum of pulley and the amplitude changing drum of moving arm shall be installed with the anti-detaching installation of steel wire rope. The gap between the name of the device and the outer edge of pulley and drum side plate shall not exceed 20% of the diameter of the steel wire rope, and the surface in contact with the steel wire rope shall not have edges and corners.
3. Jacking anti-trip device
When the jack-up tower crane is misshapen to add or lower sections, the jacking device will come out of the supporting structure of the tower or the connecting structure of the end of the oil cylinder.
4. Anti-falling device for trolley
In order to prevent due to variable amplitude car wheel failure caused by the car fall off the arm. The trolley anti-falling device should be set for the trolley luffing tower. Even if the wheel is in effect, it is possible to ensure that the trolley does not fall out of the boom.
5. Buffer and stop device
Stop device should be set at the end of track stroke of tower crane walking and trolley amplitude changing. The buffer device is on the stop device or the tower crane (amplitude changing trolley). When the tower crane collideswith the stop device, the buffer device should enable the tower crane to park stably without intense impact.
6. Anti-wind and anti-skid device (rail clamp)
For tower cranes running on the track, anti-wind and anti-skid devices should be set in non-working conditions to prevent the traveling tower cranes from sliding on their own when subjected to strong winds, causing overturning.
