Telescopic cylinders are preferred for dump trucks because they offer a long stroke from a compact unit and can handle imbalanced loads. When front-mounted, these cylinders provide the additional benefits of increased front-of-body leverage and reduced stress on the dump body frame. It’s an ideal and reliable solution for extra-large trucks carrying heavy loads. Even …
Before purchasing a replacement hydraulic cylinder for a dump truck body, it is important to understand your truck’s specifications, lift measurements, and criteria to ensure your hydraulic cylinder can meet your daily work demands.

Most single acting dump truck cylinders have 2 ports on the main barrel or body. One port is typically located towards the top, or plunger end. The second port is generally positioned at the other end of the cylinder near the base, or blind end. The versatility of two ports allows cylinder manufacturers to make …
Many hydraulic cylinder manufacturers have shifted to a bleederless design for dump truck cylinders. The primary advantage of this new design is to automatically purge any trapped air from the installation process. Traditional bleeder designed dump cylinders have an open plunger end which allowed the plunger to fill with oil. Any air captured in the …
Bleeding air from your system is critical to maintaining or installing dump truck cylinders. Trapped air can contaminate your system’s hydraulic fluid, leading to degraded performance, damaged component parts, cavitation, and, in extreme cases, complete hydraulic cylinder failure. Luckily, bleeding hydraulic cylinders is a straightforward process. By releasing the pressure from a hydraulic cylinder bleeder …
Dump trucks are used in a variety of industries and for many purposes. Dump trucks carry loose material such as soil, rock, or road salt. Some dump trucks are capable of carrying payloads up to 26 tons. With a capacity for high payloads, rollovers are a major consideration for dump trucks. Drivers should always obey …
Standard Operation for a Telescopic Cylinder To explain what causes miss and slam during telescopic cylinder function, let’s first review the standard operation for a telescopic cylinder. Telescopic hydraulic cylinders feature a series of steel tubes, called stages, that are nested inside each other. Most standard telescopic cylinders feature anywhere from 2 to 5 stages. This design …
