Hydraulic Cylinders – Single Acting
|
|
|
|
Single Acting with Spring Return
5 to 100 ton |
| |
These cylinders are designed and manufactured to
work in the toughest environments to which this type
of equipment is normally subjected.
Robust construction
with long guides allow the units to withstand abuse
and better tolerate eccentric
and side loading, yet is convenient to use with only
one quick-release coupler hose connection and a spring
return. |
| |
| Features |
- Yale ChroMo Design
- Operating pressure max. 700 bar
- Single acting with spring return
- Robust design with long piston bearings to withstand
eccentric loading
- Cylinder body and piston are made from chromium-molybdenum
steel and heat-treated
- Hard-chromium plated piston with replaceable,
heat-treated saddle
- Metric mounting threads on cylinder collar, in
the base and piston rod (5 to
30 ton)
- Stop ring can bear full capacity (pressure) and
is fitted with dirt wiper
- Oil port thread: 3/8 NPT
- Incl. Female coupler half CFY-1
- YS-50/100 and YS-50/160 with carrying handle
- YS-50/320 to YS-100/200 with lifting rings
|
| |
| Applications |
Universal cylinders are designed for all jobs where
high forces but compact dimensions are required: e.g.
straightening of steel constructions, removing of parts
like shafts, axles, lifting, positioning, weighing,
supporting, testing as well as for all general assembly
and repair applications.
Due to the various mounting
threads, the cylinders can easily be installed in clamping
devices, welding
fixtures, frames presses, etc. |

(Low Height)
(Flat Cylinders) |
YLS – Low
Height
YFS – Flat Cylinders
|
Single Acting with Spring Return
10 to 100 ton |
| |
These very compact hydraulic cylinders are designed
for lifting and positioning jobs as well as all general
maintenance applications, where low height, portability
and light weight are needed.
These versatile cylinders
are found in all industrial areas like steel mills,
civil engineering, heavy
construction industry, power plants, off-shore
industries, etc.
Low height cylinders are recommended
for all lifting, pushing, levelling, pressing applications
especially
in tight working areas. Due to their short strokes,
flat cylinders should not be subject to side loading. |

| Features |
- Yale ChroMo Design
- Operating pressure max. 700 bar
- Single acting with spring return
- Low height for tight working areas
- Cylinder body and piston made from chromium-molybdenum
steel and heat treated.
- Stop ring can bear full capacity (pressure)
and is fitted with dirt wiper.
- Oil port thread: 3/8 NPT
- Incl. Female coupler half CFY-1
- YLS-100/55 is equipped with 2 lifting rings.
- YFS-100/15 comes with a carrying handle

Single acting with spring return
12 to 93 ton |
| |
| Due to the centre hole design a threaded rod can
be placed through the hollow cylinders so that extremely
high pulling forces can be achieved. |
| |
| Features |
- Operating pressure 700 bar
- Single acting with spring return
- Large centre hole diameter
- Cylinder body and piston made from chromium-molybdenum
steel and heat treated
- Double bronze bearing of the hard chromium-plated
piston
- Metric mounting threads at cylinder body
and inside of piston
- Interchangeable hardened saddle
- Inner and outer dirt wipers
- Oil port thread: 3/8 NPT
- Includes female coupler half CFY-1
- From YCS-21/150 with carrying handle
- From YCS-57/70 with 2 lifting rings
|
| |
| Applications |
| Hollow cylinders are used as the power component
within hydraulic puller sets, for pre-stressing of
anchor bolts, removing of axles, shafts, bushings,
extracting of tubes, as well as for heavy duty pulling
applications. |

With Safety Lock Nut
Single Acting
30 to 1100 Ton |
| |
Hydraulic cylinders with safety lock nuts are
recommended when loads have to remain in the lifted
position
over a period of time.
The safety lock nut ensures
a positive hold in any position and work can
be carried out beneath
the lifted load.
Hydraulic pressure can be released
so that cylinders work like mechanical supports.
Pumps
can be separated from cylinders. |
| |
| Features |
- Operating pressure 700 bar
- Single acting with gravity return
- Special guiding bands for ideal piston guiding
- Hard-chromium plated piston with trapezoid
thread
- Over-flow hole ensures a definite piston
end stop
- Interchangeable hardened saddle
- Tilt saddles as an option.
- Oil port thread: 3/8 NPT
- Incl. Female coupler half CFY-1
- Spring assisted return of the piston can
be quoted on request up to 340 ton capacity.
- All cylinders with lifting rings
|
| |
| Applications |
For all heavy duty jacking applications where a
special safety factor is appropriate like lifting
and lowering of bridges, supporting of buildings
and foundations, jacking up of heavy machines, steel
sections, ship modules or similar loads.
Various applications
in civil engineering and construction, steel fabrication,
power plants,
heavy repair and assembly jobs, ship building,
off-shore, etc. |

YPL – Pull Cylinders
and
YPP – With Integrated Hand Pump
|
Single Acting with Spring Return
10 to 51 ton |
| |
Yale pull cylinders are able to create extremely
high pulling forces and can be controlled precisely
by the use of hand pumps or power packs.
In neutral
position, pull cylinders are fully extended. As
soon as the cylinders are pressurized
the forged links are drawn together.
A built-in
return spring extends the piston again as soon
as the pressure is released. |
| |
| Features |
- Yale ChroMo Design
- Operating pressure max. 700 bar
- Single acting with spring return
- Can be operated in all positions (except
YPP Hand Pump)
- Cylinder body and piston are made from chromium-molybdenum
steel and heat treated
- Double bronze bearings
- Stop ring can bear full capacity and is fitted
with dirt wiper
- Forged replaceable links
- With carrying handle and piston protection
cover
- Oil port thread: 3/8 NPT
- Incl. Female coupler half CFY-1
|
| |
| Applications |
| Ship building, heavy vessel construction, steel
construction, civil engineering as well as general
