Multi Stage Telescopic Hydraulic Oil Cylinder for Heavy Truck Front
1. Retractable hydraulic cylinder can get a longer working stroke
with multistage sleeve-shaped piston rod hydraulic cylinder,
telescopic hydraulic cylinder, also known as multistage hydraulic
2. Telescopic hydraulic cylinder is composed of two or more piston
hydraulic cylinder set.
3. The piston rod of the previous stage piston cylinder is the
cylinder of the latter piston cylinder.
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.

• It has FC, FE, FEE.
Any model could be customized, Please note that the regularly stocked telescopic cylinders above.

• There are many benefits to using a single acting dump truck
cylinder. It’s the ideal choice for applications where gravity,
weight or other assisting forces are present to move the cylinder
in one direction. It could be mounted in any position so that it
could be used in a wide range of mobile and industrial
• Every DALLAST single acting telescopic cylinder is individually
tested before leaving our plant to assure proper performance and
leak-free operation. All cylinder products carry an 12 months
• Snap on glass filled bearings that absorb contaminants without
damaging cylinder walls.
• Nylon tipped set screws that conform to packing nut threads to
decrease the probability of packing
nuts backing off.
• Single-acting cylinders transfer force and motion in one
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,
welcome to consult.
