Mechanical Shifting with Reliable Self-Locking & Indexing

Safe shifting with automatic mechanical locking ("engaging" or "indexing") has become a standard in mechanically controlled machines and machine components.

The Copier Shift & Engage Lever is the ideal universal fail-safe locking & indexing lever for precise shifting. The lever has a high reliability and is used in several industrial applications: speed change gears, clutches, valves, valve actuators, control mechanisms, assembly equipment, test rigs, and special machines. The Copier Shift & Engage Levers are built to stringent requirements.

Typical characteristics of the Copier Shift & Engage Levers are:

universal fail-safe lock (automatic click-in effect)
safe locking (indexing) system, secure against shock and vibrations
single-handed operation
pull or push operation
any position realized by a mechanical lock

Numerous applications in the industry prove the quality of the self-locking technique realized by Copier Shift & Engage Levers.

Shift & Engage Lever Series

Copier Shift & Engage Levers may be easily integrated in existing machine design. Any shift position is possible for your choice. The levers are installed independent of the location.

Series LN 100-2: Drilling the position hole during assembly - (pin-lock)

Series LN 300-2: Shift position on customer request - (slot-lock). The shift positions must be defined before lever assembly.

Series LN 400-2: Number of shift positions depends on the number of teeth (360 degrees) - (tooth lock).

The shifting shaft of models LN 110-2, LN 120-2, LN 310-2, LN 320-2, LN 410-2 and LN 420-2 are guided by a self-lubricating bushing. One of the remarkable features of these levers is their reliable seal of the attached flange and the shifting shaft (also in oil).

Application Examples

Special Features

All Copier Shift & Engage Levers have the distinction of being equipped with enhanced bearings, as well as the especially for the models LN 110-2, LN 120-2, LN 310-2, LN 320-2, LN 410-2 and LN 420-2 designed Copier Dual Sealing. For this reason these models even withstand rough conditions regarding the density. The remodeled lever casing meets state-of-the-art design aspects. By default the lever is equipped with an ergonomically shaped lever knob.

Maximum allowable torque T [Nm] at the shifting shaft

For the engaged Copier Shift & Engage Lever the following maximum torques T [Nm] are valid depending on the shifting shaft diameter d1. The shifting shaft must not be operated above this limit!
