Custom Single-Acting Telescopic Hydraulic Cylinder for Dump Trucks
APEX Hydraulic offers custom single-acting telescopic hydraulic cylinders designed specifically for dump truck applications. These cylinders provide a long lifting stroke from a compact retracted envelope, enabling efficient dumping of heavy loads. Available in single-acting gravity-return configurations, they are engineered to generate high starting force for fully loaded bodies and operate reliably in dusty, muddy, and outdoor environments.
Key Selling Points
- Long Stroke from Compact Design: Multi-stage telescopic construction provides extended stroke while minimizing retracted length, fitting limited chassis space.
- High Starting Force: Largest stage diameter engineered to deliver the required initial lifting force for loaded dump bodies.
- Customizable Stages: Number of stages and stage diameters customized to match specific stroke and load requirements.
- Gravity Return: Single-acting design allows body lowering via gravity, simplifying the hydraulic system.
- Application-Specific Mounting: Trunnion, cross-tube, ball, or clevis mounting options to fit various dump body geometries.
- Protected Sealing: Heavy-duty wipers and seals resist dust, mud, and moisture for dependable outdoor operation.
