In its 175 years of experience, Lock has achieved the optimum level of synergy between materials and manufacturing processes to create robust, self-locking gear units.
A complete product family assures an optimum selection of gear units for loads of up to 12000 N or torques up to 160 Nm.
The load figures and crank force given by Lock levels reflect reality. The maximum load-bearing capacity of the manual drives depends on the strength of the operator.
With the HZW in conjunction with the rack drive and rack gear geometry developed in-house is a product unrivalled to this day.
