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).
