The purpose of the hoisting gear on a crane is to transform the high speed / low torque of the motor to low speed / high torque – in other words, a force suitable for lifting and lowering the load. 

A Konecranes gearbox is a fully-integrated core component consisting of gears, shafts, bearings and housing. Every gearbox that we produce has been designed specifically for crane applications.

Together, the gearbox, motor and control system are what we call the Core of Lifting.

A crane using Konecranes Core of Lifting gears lowers power consumption, reduces waste, cuts wear, and uses fewer parts. All of this adds up to more productivity and less cost.

How do we do it?

• With a low mass of rotating parts, Konecranes gearboxes reduce inertia, and lower both the need for energy and lubricating oil. In addition, the right distribution of tooth force provides a high load carrying capacity. Combined with an optimized gear housing, this further decreases noise and vibration, which makes the gearbox even more power efficient.
• Traveling machinery has no additional couplings or shafts, reducing wear and offering better approach dimensions thanks to its compact size.
• Ultimately, this innovative design gives safer, more productive equipment with minimal downtime.

• Our 3D modeling process guides our engineering so that we fully account for the stresses on gearbox components, right down to the smallest detail, to avoid deformation, fractures and wear. Smooth tooth contact patterns minimize pressure on gear parts and reduce the risk of damage.
• Because we produce the Core of Lifting gear components ourselves, we can ensure the quality of every gear wheel and shaft.
