CUSTOM HEAVY DUTY
RAM Heavy Duty cylinders are characterized as a robust cylinder design capable of handling harsh
operating environments. The cylinder design typically incorporates a bolted gland configuration for increased
strength, and specialty seals to handle higher operating pressures and potential pressure spikes common in
these applications. Cylinder components, including barrels, shafts and mounts, may be designed with exotic
metals and/or heavier materials to ensure stability and longevity of the cylinder under tougher conditions.
Examples of applications where a heavy duty design is used include BOP (blowout preventers), excavators and
attachments, land scrapers, paving equipment, pay loaders and attachments, gravel crushers, log skidders,
catwalks, and hydraulic wrenches. RAM has the expertise and experience to design and build your unique
heavy duty cylinder requirements.

larger diameter cylinders may be accommodated. A wide range of equipment relies on this type of cylinder
design. Big bore cylinders are used in building moving equipment, hydroelectric dams, ferry platforms, rail
running gear, rig moving platforms and walking systems, bridge installations, hay compressors, suspension
systems, and industrial presses. Rely on RAM for a big bore design that complements your specific application.

SMART CYLINDERS
RAM Smart Cylinders are designed to incorporate position sensing technologies for end user
applications. Referred to by many names such as: electronic position-sensing, electro-hydraulic control,
intelligent cylinders and smart cylinders; this technology utilizes linear transducers (sensors) to
communicate the cylinder’s piston position back to the overall hydraulic system.
Increased control, functionality and sensor-instrumented cylinders are becoming more important and
more common in heavy industrial, mobile, and agricultural equipment.
RAM can incorporate position sensing technologies in any custom designed hydraulic cylinder.
A variety of bore sizes, stroke lengths, and mounting options can be configured to meet your overall design
and industry needs.
EXTERNAL SENSOR SOLUTION
An external sensor option involves mounting a transducer externally onto a standard carbon steel cylinder.
The cylinder position is measured when a pre-fitted permanently embedded magnet in the piston is moved
by hydraulic pressure. The externally mounted transducer allows equipment operators and maintenance
personnel to access and replace the sensor if necessary, and needs no deep drilling costs. This method is
recommended for cylinders that are not exposed to harsh environments.
INTERNAL SENSOR SOLUTION
An internal sensor option involves the transducer being configured for mounting inside a cylinder. This
internal configuration features a hole drilled down the center of the shaft rod. The cylinder end cap is
machined to accommodate the transducer. This method usually consumes the least amount of space,
however, the transducer is less accessible than mounting it externally. This method of a protective
enclosure shields the transducer from certain environmental conditions, thus increasing its life span.
Some applications where Smart Cylinder technologies have been implemented include:
Height control on spray booms
GPS controlled steering
Bucket postion control
Trailer outriggers
Snowplow control sensing
Stabilize cranes
Asphalt depth control

CUSTOM TELESCOPIC
TELESCOPIC DESIGN OPTIONS
Telescopic cylinders provide a long stroke from a very compact retracted length.
RAM has experience designing telescopics for a number of industries and applications and
can work with you to design a single acting, a single acting/double acting combination, or a
double acting design.
SINGLE ACTING
Telescopic cylinders are the simplest telescopic design.
A single acting cylinder is extended using hydraulic pressure but is retracted using external forces
(usually gravity), once the hydraulic pressure is removed.
Contact RAM Engineering to custom design a telescopic cylinder to fit your specific needs.
OPTIONAL FEATURES
Working Pressure: Up to 5000 PSI
Stages: 2 to 5 working sections
Barrell Size: Up to 20” diameter
Barrell Material: Alternative tube stage coatings available including nitrided, chrome over
nickel, plasma spray
Rod Size: Stroke lengths up to 480”
Rod Material: Carbon steel, precision honed, hard chrome plated stages
Piston: Optional integrated machined piston design
Gland: Steel or ductile internally threaded
End mounts: Trunnion, clevis, tang, cross tube, spherical bearing, custom bushing,
cross drilled hole
Valves: Optional integrated valves
Ports: Custom arrangements for size, type and location options
Seal Options: Urethane wiper seals, modern urethane lipped shaft seal, modern urethane
one piece static seals, glass filled nylon gland bearing rings, glass filled nylon
piston bearing rings, cast iron piston rings, interlocking step-cut reinforced
heat stabilized thermoplastic zero leak piston rings, and custom sealing
arrangements for high or low temperature, high cycle or continuous duty
18
SINGLE/DOUBLE COMBINATION Telescopic cylinders
are a single acting telescopic cylinder where one or more of the smaller stages are double acting.
A typical application is a mast raising design on a drilling rig where the load must be pulled over
center until gravity can take over to retract the cylinder.
DOUBLE ACTING Telescopic cylinder designs are extended and retracted
using hydraulic pressure. A double acting Telescopic cylinder is a more complex design and involves
additional sealing within the internal body of the cylinder to seal off the different stages.
Passageways are machined into the internal components of the cylinder to allow for proper
staging. This type of design is usually utilized when gravity is not available to retract the cylinder.
19
