Pull hydraulic cylinders, single acting spring return in high pressure. Pull force from 2 to 100 tons with a stroke range from 75 mm to 160 mm. Suitable for diversified uses and for pulling operations. Operating pressure 700 bar. Guide surfaces are sized to guarantee optimal performance in absorbing the offset load and the end stroke ring increases safety for the operator by avoiding the extra stroke of the piston. Hydraulic jacks equipped with high strength gaskets for maximum durability up to 60° C, upon request it is possible to equip the cylinder with gaskets resistant to high temperatures up to 200° C. Furthermore, the presence of the wiper prevents contamination from impurities present in the environment of use. Pull hydraulic cylinders are equipped with a 3/8 “NPT female coupler equipped with an anti dust cap, available different attachments and accessories. External painting for maximum corrosion resistance or Nitox ONC treatment on all internal mechanical parts for maximum resistance to corrosion and wear. All models weighing up to 20 kg are equipped with lifting eyebolts. Sectors of use: steel mills, energy, industry, infrastructure, engineering and testing, mining, shipbuilding, offshore, oil & gas and transport. Possibility to design and produce custom made hydraulic cylinders on request, with dedicated geometries, performances and features. All models can be connected to different drive units such as hand pumps or electric, air, petrol pumps. A wide range of accessories such as hoses, valves and pressure gauges are available for the composition of the desired hydraulic circuit.

Custom design
Custom pull cylinders, available in single or double acting versions, can be engineered on request with tailored geometries, performance parameters, and specific features

Accessories – Versatile Threaded Design
CRM-TR models feature threaded sections on both the body and piston, allowing easy integration of accessories such as chains, heads, and extensions.

Safety Warning – Spring Disassembly
If disassembly is needed, do not position yourself axially with respect to the spring; unscrewing the guide ring without caution, the compression spring can injure the operator (being very pre-loaded).

Treatment
Single acting pull cylinders can be manufactured with external painting on cylinder body or NITOX ONC treatment on all mechanical surfaces.
