Lifting Cylinders

Lifting Cylinders for Tail Gate and Lift Gate: Bearing Force in Every Operation

The lifting cylinder is the central force-generating component of every tail gate. It converts hydraulic pressure directly into linear lifting motion, enabling precise, smooth raising and lowering of the platform – reliable, controlled, and consistent even under heavy loads. Without a functioning lifting cylinder, safe operation of any lift gate is impossible. SULEJ Ladebordwand supplies tested lifting cylinders as original spare parts for common system manufacturers – matched to maximum load capacity, precise lifting speed, and lasting safe performance in daily transport operations.

Design and operating principle: how the lifting cylinder drives the tail gate

The lifting cylinder consists of a precision-honed cylinder tube, a piston with high-quality sealing system, and a hardened, hard-chromed piston rod. As soon as the hydraulic pump delivers oil under pressure into the cylinder chamber, the piston displaces and transfers the generated force via the piston rod to the lifting mechanism of the platform. The motion is smooth and precise to the millimeter. Single-acting designs rely on the platform's own weight for the return stroke; double-acting lifting cylinders provide active hydraulic control of the lowering motion – for greater precision and better control even under heavy loads.

Types and features: the right lifting cylinder for every lift gate

Single-acting lifting cylinders: Hydraulically active in the lifting direction only – lowering occurs through the weight of the platform. Low-maintenance, robust standard solution for many tail gate types.

Double-acting lifting cylinders: Hydraulically controlled in both directions – for maximum controllability, particularly under high loads and varying operating conditions.

Telescopic lifting cylinders: Multi-stage design for large lifting heights in compact installation spaces – preferred in tail gate systems with limited mounting clearance.

For the high demands of daily transport, piston rods made of hardened, hard-chromed steel are used. The chrome layer provides lasting protection against corrosion and abrasion. Precision-honed cylinder tubes ensure dimensional accuracy and smooth operation. High-quality sealing systems with scrapers (PU, NBR or FKM depending on application) prevent oil loss and protect the hydraulic oil from contamination.

Maintenance and inspection: keeping lifting cylinders operational long-term

Regular visual inspection is the foundation of trouble-free operation. Check the piston rod for scratches, dents, or signs of corrosion – even minor surface damage can attack the seals and lead to oil loss. All hydraulic connections should be checked for leaks at every maintenance interval. Timely replacement of hydraulic oil according to manufacturer specifications preserves lubrication and protects the entire sealing system. For vehicles with tail gates used outdoors daily, protective tubes or bellows are additionally recommended as protection against dust, moisture, and mechanical impact.

Quality matters: why tested lifting cylinders are essential for lift gates

Lifting cylinders are among the safety-critical core components of every tail gate. Inferior designs increase the risk of leakage, pressure loss, or system failure – with potentially serious consequences for cargo, vehicle, and operators. SULEJ Ladebordwand exclusively supplies tested lifting cylinders and spare parts made from high-quality materials, precisely matched to the technical specifications and installation dimensions of common manufacturers – for safe, reliable performance and long service life without compromise.
