Welding Flange Construction Cylinder: A Popular Choice

The three major and most common types of cylinder configurations can be distinguished into ram-style, tie rod and welded cylinders.

As understood by the name, ram cylinders are utilized in heavy-duty applications. They are involved in pulling the load rather than pushing the load.

The tie-rods are typically situated on the outside housing of the cylinder to provide an extra stability.


The welding flange construction cylinder has end flanges that are welded onto the barrel and an end cap is attached with each flange. The end cap is secured in its place by bolts which slip through the holes in each of the end cap and thread into tapped holes in every end flange. This structure is more compact and lighter than the regular tie-rod configuration, and this explains why the welded cylinder finds wide application in varied mobile equipments.

A variant to this creation comprises each end cap that is threaded into the ending of the barrels. This construction, on the other hand, usually cannot hold as much of high pressure rating as held by welded cylinders and they are also more difficult to reassemble and disassemble.

There are many hydraulic cylinder manufacturers that manufacture a huge variety of hydraulic cylinders like trunions, telescopic and clevis etc.

Essem Engineers are known to be a huge name in the world of hydraulic cylinder manufacturers. The welding flange construction cylinders offered by them are without doubt flawless and work for long durations without any damage. As a result no repairing and servicing is required for a long time.

The Superior Hydraulic Presses & Machines

Hydraulic presses are devices that use hydraulic cylinders to produce a compressive force. The press uses the hydraulic equivalent of a mechanical lever and was also known as the Bramah press, named after its inventor, Joseph Bramah, from England.

Joseph Bramah invented the hydraulic press and was also issued a patent for its invention in 1795.

The following process is followed by the press:

1) The operator first manually places the cutting die on top of the material, swings the arm or beam over the die.

2) The press arm descends and gently presses the die through the material.

The hydraulic presses are used extensively across many modern industries ranging from aircraft to hoist cranes to heavy plant machinery such as excavators.


The hydraulic press functions based on the Pascal’s principle, i.e. the pressure throughout a closed system is constant.

One part of the system is a piston acting as a pump, with a modest mechanical force acting on a small cross-sectional area; the other part is a piston with a larger area which generates a correspondingly larger mechanical force.

Only small-diameter tubing (which more easily resists pressure) is needed if the pump is separated from the press cylinder.
Hydraulic presses and machines are often used for clinching, forging, punching, moulding, metal forming, deep drawing and blanking operations.

In the hydraulic machines category, the broaching machines are known for their accuracy and superior finish.Broaching is a highly innovative metal cutting process, wherein the metal is detached by successive actions of the cutting teeth number incorporated in the tool called Broach.

Broaching machine manufacturers provide good returns in terms of productivity and quality. Productivity expansion may take place at the rate of ten times more if broaching is used as a procedure. This is due to the fact that the rate of metal removing is much greater if broaching is used.

Essem Engineers is a leading manufacturer in the Hydraulic equipment category and has been showing its prowess in this domain through the years.

Durable and Robust Special Purpose Machines

Apart from transportation, the proper loading and unloading of the machines is a tedious task. Without the proper equipment, this can be hazardous for the people involved in loading and unloading and of course, the machine can also be damaged.

The special purpose machines are costly because of the expertise involved in making them and a minor damage is enough to increase the financial expense of a site. To make this task easy, a simple yet effective machine is used called as dock leveler.

A dock leveler is an adjustable platform which is used to fill the gap between the dock and the carrier. These can be operated manually, or can be powered by a direct source or a battery. These have high load bearing capacity ranging from 500 to 10,000 Kg. These can be raised to the height of about 120 – 140 cm.

The mode of operation is not limited to the above three types. These can be hydraulic or air – powered and can be used by anyone. Any special training or a trained person is not required to operate these levelers. These are easy to install and have a robust built.

For your needs of the special machine, Essem Engineers are one of the best dock leveler manufacturers in India and have been in this business for a decade. They can be contacted on call or you can drop a mail on info@essemengineers.com.

Multi – Stage Hydraulic Cylinders

The use of hydraulic power makes the difficult work smoother and easier. Attaining a specific degree of inclination can be difficult without proper instrumentation. A multilevel telescope cylinder makes this possible.

A telescopic hydraulic cylinder is used to achieve the inclination. These are primarily of two types, the single acting telescopic type, and the double acting telescopic cylinder type. Both of these are used in several areas.


The most common example of the use of a telescopic cylinder is in a dump truck. In order to throw away the trash, the container part of the truck needs to be raised at an angle of about 60 degrees.

The multi-stage cylinder makes this task easy, as it can rise up to a certain percentage of its height. The system has stability due to the use of hydraulic fluids. For a lighter cylinder, compressed air control is used. The construction of these cylinders is very precise. Each stage is supported by at least 2 bearings such that proper rigidity is given when the cylinder rises.

Constructing a hydraulic cylinder is tricky considering its work of collapsing and expanding to 20 to 40 % of its height. A lot of expertise is required to bring out the best product. Essem Engineers are well known hydraulic cylinders manufacturers and have been in this industry for more than a decade. The manufacturing units are built according to the safety standards.
