3069S -TELESCOPIC CYLINDER STANDARD/BALL 4 EXTENSIONS STROKE 1990 Dia.112

General description

All telescopic cylinders are efficient, powerful and reliable. They consist of several extensions (from 2 to 10 extensions). The cylinder are designed to operate at an operating pressure of 180 bar. Maintenance of the tipper cylinder is simple - only with seals.

Use

Telescopic tipper cylinders are used in various industries such as agriculture, construction and mechanical engineering. They are intended for one, two or three-sided tippers and other cargo superstructures.

Production

di Natale-BERTELLI has been manufacturing since 1970. It is the only Italian factory and one of the few in the world to use »tenifer protection« for piston rod protection of telescopic cylinders. Many years of experience and research have made it possible to improve the quality of production expansions.

Cylinder protection

The piston rods of the cylinders are protected by tenifer, a compound that is chemically resistant, this increasung reistance to oxidation and corrosion. Intermetallic compounds produce an excellent anti-friction layer that allows extensions to slide against the steel. The thickness of the joint layer is 0.25 to 0.3 mm with a minimum hardness of 570 HV, against 180 HV of standard steel, it is especially resistant to dirt, dust, stone. Tipper cylinders are not painted or otherwise protected

Installation safety precautions

When varnishing or. when painting, always protect the upper part so that the paint does not damage the seals. Install the safety valve on the hydraulic system set at 200 bar. While cleaning the inside of the tanks and the appropriate filters, air must not escape into the system. When the body is lowered, the piston rods must not be under load (the adjustable clearance must be at least 20 mm). The cylinder must not be flushed directly with a high-pressure jet.
Use mineral hydraulic oils and lubricants with a viscosity of 2 to 6 at 50 ° C

Recommended density:

- ISO 22 at temperatures from -18 ° C to + 5 ° C

- ISO 32 at a temperature from 0 ° C to + 25 ° C

- ISO 68 at temperatures from -10 ° C to + 38 ° C

Importat safety instructions

Never exceed the maximum working pressure. Always provide a load within the maximum load. Always make sure the load is evenly distributed. Place on a solid and level surface. The vehicle must be stationary when tipping. Ensure a safe work area. Never touch the safety valve. Failure to follow the safety instructions will invalidate the warranty on the cylinder.
