The Three Components
A rack-and-pinion winch consists of three components: a manual drive, a rack, and a backstop. In the product configurator, we tailor these three components to your specific application. The result is a complete, technically tested rack-and-pinion winch that meets your requirements.

Manual Drives
Lock’s manual drives are designed for loads ranging from 1,000 N to 100 kN and torques up to 160 Nm. They lift, lower, adjust, and secure loads with robustness and reliability.
Manual rack-and-pinion winches with self-locking worm gear can be coupled for linear and planar loads—supplemented by the wall-mounted winch according to DIN 7355 and the manual chain drive for high-mounted shafts.
Rack
The racks, featuring a specially developed tooth geometry, are designed for manual drives and ensure smooth, robust operation. The treated surface ensures high wear resistance, and the teeth can withstand tensile and compressive loads.
Lengths up to 6 meters and custom drilling patterns enable precise installation—even in combination for linear and surface loads.
Overrun Protection
The overrun protection limits the travel distance and prevents the rack from running out of control.
This ensures that the load remains securely held in place and prevents damage to the structure—ensuring safe operation of your application.

FAQ
Rack-and-pinion hoists are used in mechanical engineering, plant engineering, and vehicle manufacturing, as well as in maintenance and platform systems.
Lock’s manual drives are designed for loads ranging from 1,000 N to 100 kN.
Yes. Multiple systems can be mechanically linked to move linear or planar loads in sync.
Mechanical rack-and-pinion hoists require little maintenance and do not need hydraulics or pneumatics. This eliminates typical risks such as leaks or pressure loss.
