The LinearChain is able to move loads horizontally and vertically.
The LinearChain is made of specially formed links, whose geometry prevents the chain from buckling under load.
This allows the LinearChain to work like a conventional linear actuator.
Framo® LinearChains are made from precision manufactured chain links of a special design which enables the chain to push as well as pull heavy loads. The chain links have a special profile with interlocking fingers at one end enabling the chain to roll or fold-up in one direction only.
When unfolded, the fingers latch together to form a rigid thrust device.
The close tolerance manufacture of the chain links and other components means that both push and pull linear motion with low backlash and high repeatability is achieved. When retracted the Push-Pull Chain folds up to occupy minimum space in relation to the required stroke.
This feature is especially of benefit where long stroke push-pull movement is required; stroke lengths of 5 metres or more are not uncommon.
The Framo® LinearChain is an alternative to standard solutions using rack and pinion, screw-jacks, hydraulic and
pneumatic cylinders or hoist mechanisms and can often present a unique solution where space is severely
limited.
The Push-Pull Chain can be selected for thrust loads from a few kilogrammes to several tonnes – even where longer strokes are required. A Push-Pull Chain drive system can be configured with standard Chain Guide Rails where there is a danger of bending movement occuring.
It is also possible to configure systems using several chains in a parallel drive geometry where higher thrust loads are required.
Benefits at a glance:
Ideal for realizing long strokes, especially for applications where space is limited
Compact storage, also in multi-axis applications
Constant, shock-free motion
Synchronous operation for horizontal or vertical motion
