Telescopic cylinders are
normally used for applications where a normal cylinder would not have enough
space to extend. They are much more expensive than normal cylinders since they
require more construction materials and a specialized design. They are only
used for hydraulic applications.
The models currently on
the market are manufactured with up to five stages and 5 hubs. The largest
bushing extends first, then the second largest bushing, and so on. Each bushing
is smaller than the previous one. For this reason, the force of the cylinder
increases, and the speed increases each time the cylinder passes to the next
stage.
This type of cylinder is
integrated into the phases where the effect of the piston expands over several
barrels, which fit perfectly into the main sleeve of reduced size. Telescopic Cylinders Suppliers provide a wide range of
cylinders for your industry.
Since most telescopic
hydraulic cylinders are mounted on a sleeve, representing almost 20% of the
actual working length, they offer a larger working stroke. If a conventional
single-rod hydraulic cylinder cannot be used, a telescopic hydraulic cylinder
will be preferred due to its compact size.
Telescopic Cylinders work on a similar
principle to single and double-acting hydraulic cylinders. The main difference
between the two types is that, in telescopic cylinders, the piston or barrel is
integrated with a compact housing with other tubes, which extend along with the
extension of the main piston or barrel.
Telescopic hydraulic cylinder applications
A simple rod system will
suffice for most equipment requiring hydraulic cylinders as they are less
complex and very reliable. However, in some situations, it will be necessary to
use telescopic hydraulic cylinders, depending on the application. For good
quality cylinders, you can contact Telescopic
Cylinders manufacturer.
Telescopic hydraulic
cylinders offer more strokes in a compact size. The long stroke, in combination
with the size, is very useful when the work surface on a vehicle or machine is
very small. Although single-rod hydraulic cylinders can be used in most cases,
here are some applications of telescopic hydraulic cylinders:
Garbage trucks
It is the most common
use of telescopic hydraulic cylinders. During unloading, a garbage truck must
reach an angle of 60 degrees. A normal cylinder cannot do this, as it would
require an extremely long rod to complete the task, which is very expensive to
implement.
Single Acting Hydraulic
Cylinders are ideal for dump trucks as the vertical movement allows for smooth
retraction. Double-acting hydraulic cylinders can be used with horizontal
movements, although retraction force must be applied.
Construction Equipment
Telescopic hydraulic
cylinders can also be installed on construction equipment. Thanks to them,
cranes can be extended horizontally to move heavy loads, while excavation
vehicles can reach greater depths.
Oil rigs
These locations use a
single rod and telescoping hydraulic cylinders. To do this, they create a
hybrid by combining both types. Since offshore oil rigs are located in small
spaces, telescopic hydraulic cylinders save space and improve performance over
single-rod cylinders.
Other uses
Window cleaning lift
systems use telescopic hydraulic cylinders. When a fixed height is reached with
the metal frame structure, the cylinders extend the top a bit more.
