L68B1 Mast Section the tower crane stop maintenance devices? What is the role of each
What are the tower crane stop maintenance devices? What is the function of tower crane stop maintenance device. Most of the construction units will use the same slogan, namely "safety in production", so it is named "thinking". The development of construction safety is the premise. Tower crane is a large-scale lifting machinery and equipment, of course, its safety can not be ignored. In addition to strengthening the technical level of personnel operation, the maintenance device of tower crane should be strengthened. So, what are the tower crane stop maintenance devices? What is the function of tower crane stop maintenance device.
1. Rope break protection device of trolley
It is used to prevent the trolley from losing control due to the breakage of traction rope of luffing trolley. For trolley luffing tower crane, two-way trolley luffing and rope breaking protection device shall be set to prevent accidents caused by trolley out of control caused by trolley traction rope breaking.
2. Tower crane wire rope anti falling device
It is used to prevent steel wire ropes such as pulley, lifting drum and boom luffing drum from breaking away from pulley or drum. The lifting drum of pulley and luffing drum of boom shall be installed with steel wire rope to prevent falling off. The gap between the device name and the outer edge of pulley and side plate of drum shall not exceed 20% of the diameter of steel wire rope. The surface contacting with steel wire rope shall not have edges and corners.
3. Jacking anti falling device
It is used for jack up tower crane to lift itself out of the support of the tower body or the connecting structure of the end of the oil cylinder during the operation of abnormal joint adding and joint dropping.
4. Trolley anti falling device
To prevent the trolley from falling off the boom due to the wheel failure of luffing trolley. The trolley anti falling device shall be set for the trolley luffing tower crane, even if the wheel is effective, it may guarantee that the trolley will not fall off the boom.
5. Buffer and stop device
Stop device shall be set at the end of track travel of tower crane travel and trolley luffing. The buffer device is on the stop device or tower crane (luffing trolley). When the tower crane collides with the stop device, the buffer should make the tower crane Park safely without severe impact.
6. Anti wind and anti-skid device (rail clamp)
The tower crane running on the track shall be equipped with anti wind and anti-skid devices under non working conditions to prevent the traveling tower crane from sliding and overturning itself in case of strong wind.
