Parker Hydraulic RAM For Dump Truck & Trailer Single Acting Long Stroke
These kinds of cylinders are called telescopic hydraulic cylinder. If we call a normal rod cylinder single stage, telescopic cylinders are multistage units of two, three, four, five or more stages. In general telescopic cylinders are much more expensive than normal cylinders. Most telescopic cylinders are single acting (push).
Commonly used in construction machinery and other mobile machinery, such as cranes, dump trucks and other hydraulic systems.
Low friction, high load piston seals with outboard wear bands are standard. Loaded lip seals and cast iron rings are optional.
Features & Benefits:
1. DALLAST single acting telescopic cylinders provide value through proven reliability, efficient performance and the quality that you expect from every DALLAST Cylinder Division product line.
2. The length of a hydraulic cylinder is the total of the stroke, the thickness of the piston, the thickness of bottom and head and the length of the connections. Often this length does not fit in the machine.
3. Snap on glass filled bearings that absorb contaminants without damaging cylinder walls.
4. Nylon tipped set screws that conform to packing nut threads to decrease the probability of packing
nuts backing off.
5. Single-acting cylinders transfer force and motion in one direction only.
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 your requirement.
Retractable hydraulic cylinder repair steps:
After opening the cylinder.
a. to clean the cylinder and piston.
b. replace all the seals.
c. if there is a valve to be overhauled, to ensure sealed and flexible.
d. to deal with all deformation sites.
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 processes.
3. The company accepted the Valet processing various types and various sizes products, processing and processing more quotes, welcome to consult.
1. We offer 12 months warranty.
2. Guarantee period is subjected to warranty instruction (1 year/ 2000 hours whichever comes first).
3. Free after-sale service during the warranty refers to problems caused by quality issues; any non quality problem occurred, we will charge the maintenance fee according to relevant standard.
4. Service Center all over the world for after sales problems.
How to choose:
1. Choice will depend on the operating conditions of the unit. It is necessary to determine the precise physical characteristics and geometry of the installation.
2. The bore, or cylinder diameter will determine the amount of force the piston can apply. Rod characteristics, usually standardized, fastening system, damping and stroke are other important factors.
3. Stroke, in particular, is an essential specification, since it defines the distance the piston travels between its initial and its final position.
4. Additional criteria include the use of presence sensors to indicate the position of the piston, the seals, purge and drain valves, type and temperature of the hydraulic fluid.
