Tilt Cylinders

Closing cylinders – locking the platform in the transport position

Closing cylinders take over the closing and locking of the platform of a tail lift at the rear portal. They pull the platform cleanly against the sealing strip at the end of the stroke and keep it under pressure in its end position while driving. At SULEJ Ladebordwand you will find closing cylinders in different stroke classes and connection patterns, matched to the installed component and available in various sizes and connection variants – a specific element for the end-position function of the platform.

Function and design – closing under load

Closing cylinders work as double-acting units and are controlled via a separate control circuit. As the end position is approached, they pull the platform with a defined closing force against the stop strip, while the main cylinders are already in their upper end position. The design is more compact than that of the lift cylinders, the stroke is significantly shorter and the working pressure is metered via a dedicated sequence valve. Rod guide and rod seal are designed in such a way that no leakage occurs even with permanent closing pressure during driving.

Wear patterns and replacement – holding the platform safely

A worn closing cylinder often shows itself by a slight opening of the platform during driving or by missing contact pressure on the sealing strip. Visible oil traces at the rod exit or pressure loss in the closing circuit are also clear indicators. When replacing, secure the platform mechanically, check the linkage points for bearing wear and replace pins and bushings together. Pay attention to the correct stroke, the matching connection pattern and the prescribed tightening torque of the high-pressure fittings.

Benefits at a glance

• Safe end position of the platform – even over long driving distances
• Double-acting design with defined closing stroke
• Robust rod guide and seals for permanent pressure during driving
• Compatible with common linkage points and control circuits

A flawlessly working closing cylinder keeps the platform tight against the rear portal while driving and prevents unintended opening on the road.
