Description
Technical Parameters
Construction industry cranes is a machine that is equipped with sheaves and cables that can lift or lower heavy objects or materials. These giant machines can often be seen in cities, rising hundreds of metre in the air to construct huge skyscrapers. Topless tower cranes remain in one place while working and are not designed to move.
Tower cranes are among the largest and most useful pieces of heavy equipment, and the importance of their maintenance cannot be underestimated. Because the repair costs and prices of new tower cranes are extremely high, modern construction companies focus on efficient execution of crane maintenance procedures. Careful operation and high maintenance standards are the main criteria driving tower cranes to exceed expected operating times.

Tower Crane Maintenance Requirements
Routine maintenance
Routine inspections focus on visually inspecting tower cranes for obvious signs of damage. Afterwards, the operator checks the hydraulic oil, base oil level and gear lubrication.
Weekly maintenance
Weekly maintenance focuses on cleaning accessible parts to minimize the effects of dirt, dust, debris and other contaminants. A clean tower crane can more accurately handle the material being lifted, while the motor and engine can burn fuel more efficiently.
Monthly maintenance
For complex machines like tower cranes, monthly maintenance procedures require skilled technicians and electricians to inspect control panels and internal components and identify electrical hazards. Any damage to even the smallest equipment parts is recorded, while preventive maintenance programs focus on introducing replacement parts in advance.
