Telescopic Hydraulic Ram 5 Stage Single Acting for Dump Truck /
Telescopic cylinders have two or more piston rods in a coaxial
arrangement to achieve greater extended length compared to the
retracted length. An external force is required to return the
cylinder to the retracted position. A typical application for a
single-acting cylinder is a lift truck, where the load of the fork
pushes the cylinder back.
a. 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
b. Snap on glass filled bearings that absorb contaminants without
damaging cylinder walls.
c. Nylon tipped set screws that conform to packing nut threads to
decrease the probability of packing
nuts backing off.
d. Single-acting cylinders transfer force and motion in one
e. Acts on the piston to push the piston rod out.
f. When manufacturing multistage cylinders, the number of stages
are able to produce, which is limited only by the physical confines
of the cylinder requirement.
g. Cylinder designs include welded and screwed type, welded and
bolted, fully bolted or tie rod or can take the form of your
h. All our piston rods are hard protection coated, such as hard
chrome plate, or if required, can be coated with an alternative
treatment more suitable to the application.
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
