User friendliness flat cylinders
The flat cylinders (also known as a jack, bottle jack, press, bottle or pump) with spring return were specially constructed tor use where the construction height is very restricted and other cylinders don't fit. The generation of short stroke cylinders was designed tor situations with a restricted construction height, which call for a small stroke. Both types of cylinder can be used in the most diverse situations and comply with the ASME B-30.1 standard. That therefore means dynamism. ease of use and safety under all conditions.
Extra handy: easy-to-disassemble spring return
Both the short stroke and the flat cylinders are fltted with a spring that pulls the plunger back after use. With average use, Holmatro recommends servicing once a year. This trequency could be higher if you use the cylinders more often under extreme conditions. To make maintenance and servicing easier, both cylinders have a spring that can be disassembled quickly and safely.
Benefits spring return flat cylinders
- Compact, flat version, efficient in case of limited insertion space
- Usable in all positions
- Standard provided with fixing holes for easy assembly
- Protected against ejection of the plunger
- Dirt scraper ring; protects against pollution and increases the life span
- Splined plunger, no saddle needed
Flat cylinders are suitable for many applications, including the installation of heavy engines, machines and steel constructions. The cylinders are also used during the transfer of propellers (either under or above water), the transfer of heavy couplers of ship propulsions and for lifting the top half of a crane off the slewing ring. Flat cylinders are suitable for installation in test presses (in connection with the extremely low construction height) and for the alignment of bridge sections, tunnel sections, viaducts, etc. They are used to set the correct weight and to unload heavy casting molds.
