A second-hand workshop overhead crane typically has a lifting capacity ranging from 1 to 20 tons and can be designed as a single-girder or double-girder system depending on application needs. The span length generally varies between 6 and 25 meters, while the lifting height ranges from 4 to 12 meters. The average traveling speed of the bridge is about 10 to 40 meters per minute, and the hoisting speed of the hook is approximately 4 to 12 meters per minute. These specifications enable precise handling of heavy loads in small to medium-sized industrial environments.
In a used overhead crane, the drive system often employs three-phase induction motors with power ratings between 2.2 and 15 kW, while the gearboxes provide reduction ratios from 1:20 to 1:40 for efficient torque transmission. Electromagnetic brakes are utilized to ensure load safety during stopping. The wire ropes used generally have diameters between 8 and 16 mm with a tensile strength class of 1770 N/mm². These technical parameters ensure that even a second-hand overhead crane maintains reliable load-bearing performance and operational efficiency.
