1- Purpose of this sequential device:

In a normal telescopic slide, the opening of the beams can be done in a nonsequential way.
The moving beam extends first. The other elements of the slide are then subjected to a torque which increases the force required to move them out.

On some slide references, a sequential opening of the beams is possible.

2- Concept:

Synchronization (or sequential opening) solves this phenomenon:

1- the moving beam is kept closed until the intermediate is completely opened.
It is therefore subjected to a reduced torque, whilst extended.

2- then the moving element can expand:

This system, which is possible on some heavy duty 3 or 4 beams slides, considerably reduces the opening forces by controlling the opening order of the telescopic slide beams.

It is achieved :

  • either by magnetic end stop,
  • or by mechanical levers.

3- Advantages of sequential opening:

  • The opening force is reduced;
  • The lifetime is increased;
  • Ball cages migration due to insufficient parallelism is reduced.

4- Limitations and contradictions:

This system is not recommended in case of vertical use (guillotine).
It also does not work in the case of high temperature installation (in an furnace).
