Telescoping Linear Actuators Available In Four Types

To accomplish movement of movement of a large load, actuators are needed and in the present scenario, the devices are present with different stroke, size and speed to support different nature of work in industries.

In this article, well come to know about telescoping linear actuators, major types and their working mechanism. The range of motion will be found many times greater in the devices. Moreover, actuating members in the devices act as rigid linear shafts when get extended. Examples of such types of actuators include:

Helical band

A specialized and a complex device which is applied in stage lifts and also material handling lifts is helical band actuators. The high-capacity telescoping tubular column comes with the capacity to lift weight of around 25,000 pounds and up to the height of 40 feet.
The principle of operation is interlocking stainless steel bands; the vertical band spirals into a stacked helix to form the column wall and the horizontal band is there to interlock spiral seam of the vertical band. The working of the device is also supported by lateral support mechanism in the form of self-guiding frame or guide rails.

Rigid belt

It is also called as zipper belt or push-pull belt devices that support push-pull and lift applications. It can also be called as belt and pinion device forming telescoping beam in order to transmit thrust and traction. Dynamic loads can be easily lifted up to 230 pounds as well as about 3 feet of travel. The principle of mechanism explains that two plastic ripped belts are there that come with evenly spaced load bearing blocks. An electric motor acts as the driven force in this device.

Rigid chain

Other names of rigid chain actuators include push-pull chain, column forming, linear chain and electric chain devices. The product is idea to get used for push-pull material handling, window operating and other lift applications. In industrial areas, the devices are meant to support lifting of loads exceeding 10 tonnes to over more than 7 metres of distance. The limited-articulation chains support the working mechanism and the chains are articulated in the manner that they easily deflect to one side from a straight line only.

Segmented spindle

The device that comes with the lifting capacity of up to 440 pounds is segmented spindle. storage magazine and electrical gear drive forms the base of the device and support to let the device move up to 16 inches.
