Hydraulic Hoist Cylinder
Multistage Telescopic — Three Hoist Types

The "hoist" is the complete tipping mechanism — and the multistage telescopic hydraulic cylinder is the power actuator at its heart. But the same cylinder performs very differently depending on how the hoist mounts it. A front-push hoist uses the cylinder at a shallow angle and often needs double-acting. An under-body hoist uses the cylinder nearly vertical and works with single-acting. A scissor hoist multiplies the cylinder's force through a linkage. Understanding your hoist type is the first step to specifying the correct cylinder.

How do I identify which hoist type my dump truck uses?

Look at where the telescopic cylinder is mounted. If it sits behind the cab and pushes forward against the body front — it is a front-push hoist. If it sits vertically between the chassis rails, directly under the dump body floor — it is an under-body hoist. If it connects to a scissors-shaped linkage mechanism that opens as the body rises — it is a scissor hoist. If unsure, photograph the hoist area and send it to Korea Ever-Power — the engineering team can identify the type from the photos.

Can I change from one hoist type to another?

Technically yes, but it requires significant structural modification to the truck chassis and dump body — new mounting brackets, new hinge positions, and potentially a different hydraulic circuit. It is not a simple cylinder swap. Hoist type changes are typically done by professional body builders during a full body replacement, not as a cylinder-only retrofit. If you are replacing only the cylinder, match the existing hoist type exactly.

Which hoist type is the most reliable?

Under-body hoists are generally considered the most straightforward — fewer moving parts (no linkage), direct vertical force application, and reliable gravity return. Front-push hoists add the complexity of angled force and double-acting requirements. Scissor hoists add the linkage mechanism, which introduces additional pivot pins and bushings that wear over time. However, each hoist type exists for a reason — they each solve specific vehicle geometry and payload constraints that the other types do not address equally well.

Does Korea Ever-Power manufacture the complete hoist assembly, or only the cylinder?

Korea Ever-Power manufactures the telescopic hydraulic cylinder — the power actuator within the hoist. The hoist frame, mounting brackets, hinge pins, and scissor linkage (if applicable) are typically manufactured by the dump body builder or a hoist assembly specialist. Korea Ever-Power supplies the cylinder component to these body builders and hoist assemblers as an OEM part. For forklift applications and aerial platform applications, the same manufacturer-direct model applies.

We build front-push hoist systems for 15–25 tonne dump trucks. The cylinder mounts at 38° from horizontal at the start of the tipping stroke. Double-acting is mandatory — the angle is too shallow for gravity return with our aluminium bodies. Ever-Power double-acting 4-stage, 5-inch bore, SAE ports. 30 hoist cylinders delivered over 12 months. The consistency is critical for us — every cylinder must fit our hoist frame without adjustment. Ever-Power delivers ±0.5 mm on every critical dimension, every batch. This is what factory-direct quality looks like.

Our fleet uses under-body hoists — the simplest configuration. Vertical cylinder, single-acting, gravity return. Ever-Power 4-stage, 5-inch bore, metric ports. The vertical mount delivers 100% of the cylinder force as lifting force — no angle loss. We specified FKM seals because our trucks operate in desert temperatures exceeding 50 °C ambient. 20 hoist cylinders, all performing well in extreme heat. Single-acting keeps the cost down — we don't need double-acting because the heavy steel bodies retract the vertical cylinder reliably.

We fabricate scissor hoists for roll-off container trucks. The telescopic cylinder extends horizontally and drives the scissor linkage. Double-acting is essential — gravity can't retract a horizontal cylinder. Ever-Power double-acting 2-stage, 3-inch bore, SAE ports. The 2-stage is sufficient because the scissor linkage multiplies the stroke — we only need 24 inches of cylinder stroke to achieve 48 inches of body lift through the linkage geometry. Four stars because I initially ordered too large a bore (4-inch) before the Ever-Power team calculated that 3-inch was adequate with our linkage ratio. Their engineering guidance saved me money on the second order.
