When the tower crane special nature of the project
needs to change the length of the attached rod, angle, the strength, stiffness
and stability of the attachment device to check, to ensure that no less than
the original design safety.
Car under heavy load have to sneak car
trend. This is mainly boom set aside on the elevation is not enough; or is
luffing mechanism ineffective braking; or is a traction rope suddenly fracture.
Under heavy load to the outside of the car will greatly increase the load
torque, there may be an accident, so it is an accident.
Hydraulic lifting beam and climbing claw
lap is not in place, in the top attack scattered risk. Track type attachment
type for use, must increase of bearing capacity of the foundation of the track
and cut off the power of walking mechanism. When attached to a building, its
stress intensity must meet the design requirements. Check the application of
theodolite tower perpendicularity attached, and adjust.
The arrangement, each device attached to
the wall is perpendicular to the distance and wall device should be in
accordance with the instructions provided. Crane accessories, for you to
provide replacement of defective parts -- parts of each part of the crane in
operation after long time exposed to the sun and rain, labor, it is inevitable
there will not be "strain" phenomenon. At this time, the replacement
of faulty parts has become the top priority of the work. The replacement of
tower crane parts, to special post operation, and must stop operation. When
stopping, not convenience and with load, and the ground should also draw a safe
area, exclusion prohibited entry. Application of wall device accessories and
tower above is the rail clamping tongs.
