Which spring tensioner/balancer is most suitable for your application ?

1. Select according to the weight of the tool or device that is to be moved “weightlessly”.

Our spring tensioners and balancers are categorised by load range (kg). The overall weight of the tool, including any connecting cables, etc, must lie within the specified load range, otherwise the spring tensioner/balancer cannot fulfil its function. The exact load required can be set individually on the balancer unit.

2. Select by the required cable length (length of travel).

The distance from the fixing point of the spring balancer to the working zone should not be included here. Example: if the balancer is to be mounted at a height of 6 metres, a spring balancer with 2 metres wound length + additional (non-wound) cable extension could be used to position the tool within the work zone.

3. Select according to desired application.

    Spring tensioners and balancers - standard versions
If the suspended tool is pulled into the working position, a constant retraction force results. Once released, the tool returns to its rest position. With the additional option of automatic latching, the cable of a spring tensioner can be fixed at increments (every 200 – 300 mm). A short subsequent tug on the cable or tool releases the latch and the tool returns to its rest position. In balancers, the required latching is obtained by means of the optional hauling chain. This is mounted on the side of the balancer and allows the cable to be fixed stepplessly in any chosen position.
On tensioners (with ungoverned winding drums) the resultant retracting force is proportional to the length of cable extended. On balancers (conically winding drum bodies) the resultant retracting force is almost linear in relation to the length of cable extended. Cable tensioners are only used with lighter weights (max. 14 kg).
