Single Acting Hollow Plunger Hydraulic Cylinder Telescopic
Multistage for Dump Truck
Telescopic hydraulic cylinder consists of two or more
piston-cylinder assembly, the piston is a cylinder piston cylinder
after the cylinder, can get a long working stroke. An important part of DALLAST Corporation's extensive list of custom
capabilities is multistage telescopic hydraulic cylinders. Many
applications needs for exceptionally long strokes coming from
shorter, more compact units. Other applications require unique
mounting to achieve their required stroke.
DALLAST has years of rich experience to meet customers’
requirements by manufacturing these type cylinders for these type
It mainly used in various types of heavy truck front lifting, such
as 8*4 truck, semi-trailer, can be widely used in mining, iron and
steel, port conditions relatively poor use places can meet from13
tons to 90 tons lifting requirements. Truck front lifting cylinder is the dumper hydralic lifting system
for lifting actuator, truck compartment or tank.

a. Every DALLAST single acting telescopic cylinder is individually
tested before leaving our plant to assure proper performance and
b. All cylinder products carry an 12 months warranty.
c. Single-acting cylinders transfer force and motion in one
d. It has FC, FE, FEE.
e. It could be mounted in any position so that it could be used in
a wide range of mobile and industrial applications.
Low friction, high load piston seals with outboard wear bands are
standard. Loaded lip seals and cast iron rings are optional. The
seal is the use of rubber or plastic seal of the elastic ring so
that a variety of cross-section ring in the static and dynamic fit
between the surface to prevent leakage. Common seal are O-shaped,
Y-shaped, V-shaped and so on. It has the advantages of simple
structure, easy manufacture, automatic compensation after wear,
reliable performance, and can be used between the cylinder and the
piston, between the cylinder head and the piston rod, between the
piston and the piston rod, between the cylinder tube and the
About piston rod:
High strength damage resistant piston rod provides 100,000 PSI
minimum yield material in 1" through 4 1/2" diameters. Larger
diameters vary between 50,000 and 75,000 PSI minimum yield
material. All rods are case hardened to 50-55 RC and hard chrome
plated to provide maximum wear life. Stainless steel is also
available. The hard chrome plated of the piston rod according to
1. Seiko secret agents, to ensure quality of the piston rod.
2. The product have to go through heat treatment - bore boring -
grinding - car processing - black nitriding and many other
3. The company accepted the Valet processing various types and
various sizes products, processing and processing more quotes,
