Determining Hydraulic Cylinder Lift Requirements Measuring the hydraulic cylinder lift requirements for a front mount, frame type, dump body might often seem like guesswork, but it doesn’t have to be. Through a few simple calculations, we can accurately determine the requirements needed to lift our fully-loaded dump body, and the stroke needed to get it …
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 …
Telescopic cylinders on dump trucks are the norm, which is rightfully so, given that these types of cylinders offer an exceptionally long stroke from a compact unit. If a dump truck is extra large and carrying a heavy load the telescopic reach will offer a reliable solution. However, when mounting a telescopic hydraulic cylinder on …
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 …
Steps to Properly Bleed Air from a Dump Truck Cylinder Single-Acting or Lift Cylinder Raise the dump body and cylinder to full extension and leave extended for several minutes to allow air to rise to the top of the cylinder. Lower the dump body and cylinder until the front of the dump body is approximately …
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: To extend the cylinder, the largest sleeve or tube moves first, then the next largest, down to the smallest sleeve or plunger. When retracting the cylinder, the smallest …
