LHA 25 double action hydraulic cylinder – for high demands

YOUR SOLUTION PROVIDER IN HYDRAULICS

PMC Cylinders has been manufacturing hydraulic cylinders and other hydraulic products since the 1950s, and many users have benefited from its experience over the years. Our success is based on our in-depth knowledge of products, applications and our customer’s needs. No job is too small, too large or too complicated for us. Our cylinder manufacturing facilities complement each other and exchange expertise and resources, all to the benefit of our customers. We now build complete systems using state-of-the-art technology in collaboration with our customers all over the world.

LHA 25 double action hydraulic cylinder – for high demands On the following pages we present our LHA cylinder range, a versatile type of cylinder designed for 250 bar which is suitable for heavy-duty mobile and industrial applications as well as harsh marine environments.

PMC Cylinders´ cylinder programme PMC Cylinders offers a standard range of hydraulic cylinders, although much of our production consists of customised special applications. We deliver cylinders with piston diameters of 20 – 800 mm and stroke lengths of up to 12 m, depending on the dimensions and design in both black and stainless steel grades.

Standard cylinders

Special cylinders

Our LHA 25 cylinders are type-approved by DNV for pressures up to 250 bar, depending on stroke length. You can design an LHA 25 yourself using our drawing generator at www.pmccylinders.se.

We manufacture special cylinders to match the customer’s needs and wishes, e.g. for

Telescopic cylinders We design and manufacture telescopic cylinders for all industrial purposes.

– industrial applications, – offshore and marine applications, – energy power plants. This includes stainless steel and subsea cylinders and units with built-in transmitters and integrated valves.

Single action/plunger cylinders We have delivered plunger cylinders for lifting bow doors on ferries, ferry quay ramps, etc. for many years.

Our LHA 25 double action hydraulic cylinder is presented on the following pages.

Most of our customers are to be found in four fields: Energy, Offshore & Marine, Mobile Systems and Industry. PMC holds a leading position in the energy field as a supplier to the wind-power industry. Our industrial customers are mainly steelworks, papermills and mining companies who automate with the help of hydraulics. In Offshore & Marine, PMC collaborates with many of the world’s leading equipment manufacturers. Mobile Systems comprise manufacturers of such things as forklift trucks, mobile cranes, logging machines and mining and construction equipment. With our service organisation we can quickly be on the spot to solve problems that arise in production. We naturally stock spare parts and other components needed to avoid needless stoppages and delays in production.

Double action hydraulic cylinder LHA 25

LHA 25, Linear Hydraulic Actuator LHA (Linear Hydraulic Actuator) 25 is a result of a joint venture between the industrial and mobile communities in Sweden and the offshore and marine communities in Norway. The result is a flexible cylinder designed for 250 bar, which is ideal both for use in both industrial and mobile applications as well as in maritime surrundings.   The cylinder has been type-approved by DNV and has standard piston diameter dimensions of Ø 32 to Ø 400 mm.
