A Telescopic Hydraulic Cylinder Can Handle Your Heavy Lifting in Athens,TN

Telescopic cylinders are very useful when your application needs a longer stroke, but also requires a compact dimension when retracted. Telescopic cylinders, also called multi-stage cylinders, are usually single action and consist of a series of sleeves. The sleeves decrease in diameter consecutively and nest inside of one another. Typical mounting options for telescopic cylinders are cross-tube and trunnion.

The way a telescopic cylinder works is, once hydraulic pressure is placed on the cylinder, the biggest sleeve extends first. Once that sleeve has reached its maximum extension, the next sleeve begins to extend. The sleeves continue to extend until the cylinder reaches its last sleeve, known as the plunger.

There are only two different kinds of telescopic hydraulic cylinders, single-acting and double-acting. Single-acting cylinders are the most common. These work using an external force, such as gravity, to retract the cylinder sleeves. When pressure is released from the hydraulic cylinder, the force pushes the hydraulic oil out and the cylinder retracts.

While there are pneumatic telescopic cylinders on the market, hydraulic cylinders are much more common. Telescopic hydraulic cylinders are especially useful when moving a heavy load.

The collapsed length of a telescopic cylinder is generally between 20-40% shorter than the fully extended length. This makes a telescopic cylinder very useful in a tight space. The ability to extend and retract, along with the ability to move heavy loads, makes a telescopic hydraulic cylinder ideal for applications such as garbage and dump trucks. Of course, a telescopic cylinder can be very useful on smaller applications too.
