With the continuous advancement of urban construction, safe operation of tower crane is of utmost importance as crucial equipment in construction projects. Today, let's share some core common sense of tower crane maintenance to help better safeguard construction safety.
Daily inspection: Details can reveal the essence of things
The maintenance of tower cranes must follow strict daily inspection procedures. Before the operation every day, the operator should carefully check the structural parts of the tower crane, carefully check the tower body, jib, counter jib and other parts, to check whether there is deformation, cracks or loose connectors. At the same time, the tower crane brake system, wirerope, pulley and other key components should also be carefully inspected. The braking system is related to whether the tower crane can stop running in time, and the wear of its brake pads needs to be paid attention to.
For the "lifeline" of the tower crane - wirerope, it is necessary to focus on. Check for broken wire, wear, rust and other problems. Once it is found that the wear degree of wirerope exceeds the specified range, or the number of broken wires reaches a certain standard, it must be replaced immediately to avoid potential major losses due to minor issue. In addition, it is also necessary to pay attention to the condition of the pulley and hook to ensure that they rotate flexibly, no stuck, and the anti-tripping device of the hook is intact.
Regular maintenance: Keep the Tower Crane in good condition
Regular maintenance is the key to ensure the long-term stable operation of the tower crane. Every once in a while, the professional maintenance team will carry out a deep "physical examination" of the tower crane. In the mechanical aspect, the transmission components are lubricated to reduce wear and extend service life. Check the fastening of each connection part and tighten loose bolts in time.
The electrical system cannot be ignored either. Check whether the line is aged or damaged, whether the connector is firm, and ensure that the electrical components work normally. At the same time, check and debug the safety protection devices of the tower crane, such as over load limit, trolley moment limit, height limiter, etc., to ensure that they can play a role at critical moments and escort the safe operation of the tower crane.
Maintenance during special periods: take precautions to ensure safety
In some special periods, such as before and after bad weather, the maintenance of the tower crane is particularly important. Before the arrival of extreme weather such as strong wind, rainstorm and blizzard, the tower crane should be strengthened, the height of the jib should be reduced, and the windward area should be reduced to ensure the stability of the tower crane in bad weather.
After extreme weather, a full inspection of the tower crane should be carried out immediately. Check whether the foundation has settled, whether the tower is tilted, and whether the structural parts are damaged. Only after confirming that everything is normal, the tower crane can continue to be put into use.
Doing a good job of tower crane maintenance is not only responsible for the safety of construction, but also responsible for the life safety of each of our practitioners. I hope everyone can keep these maintenance common sense in mind, so that the tower crane can operate safely and efficiently on the construction site, and contribute more power to the construction of the city!
