The gears and pinions provide torque transmission in the travel and stroke gears and directly affect the smooth running of the entire machine.
We supply spare parts in a design appropriate to the specific type of gear, the required load and the nature of the operation. We focus on precise gear geometry, appropriate material selection and appropriate heat treatment to ensure smooth running and wear resistance.
We can also replace original, no-longer-available parts and adapt new components to existing shafts and fits to keep equipment operational without major design changes.
Gearboxes are an essential element of crane drives - they transmit motor power to the wheels or rope drums and determine the speed, smoothness and character of movement. The design always takes into account the operating load, the number of duty cycles, the type of start-up and the speed control requirements.
We supply gearboxes for new cranes as well as replacements for retrofitting existing equipment, including designing the appropriate mounting and connection to the current drive system.
The aim is reliable, quiet and safe operation with long service life and minimal maintenance requirements, adapted to the specific operating conditions.
A gearbox generally consists of a drive and driven shaft, a toothed gear and a housing. The housing usually consists of a cover and a sump. The gearbox housing may be designed as a casting or a weldment or a combination thereof. Lubrication is by oil. It can be pressure (by means of a gear pump) or spray.
The size depends primarily on the torque that needs to be transmitted from the motor to the crane's own drive gear.
