It has safe and reliable. The "generator" side of the hydraulic system is the hydraulic pump which brings in a fixed or regulated flow of oil to the bottom side of the hydraulic cylinder.


Dustproof ring against dust and dirty. The barrel is closed on each end by the cylinder bottom also called the cap end and by the cylinder head where the piston rod comes out of the cylinder. The piston divides the inside of the cylinder in two chambers.

Competence in working under bad situations. If we assume that the oil pressure in the piston rod chamber is approximately zero. A hydraulic cylinder is the actuator or "motor" side of this system.

The hydraulic pressure acts on the piston to do linear work and motion. Working of jack The hydraulic cylinder consists of a cylinder barrel in which a piston connected to a piston rod moves back and forth.

The piston pushes the oil in the other chamber back to the reservoir. Ground Breakers……The auto Mobile Company 8. The piston rod also has mounting attachments to connect the cylinder to the object or machine component that it is pushing. The piston has sliding rings and seals. D L connectirs Dia. Our company will fit the electric hydraulic car jack. When current is supply to jack its rod came out.

Some local manufacturers are making these jacks in Pakistan. After launching in Lahore we will grow our product in other cities. Industry Analysis Main industry which deals in electric and hydraulic jacks are in china.

Positioning Statement Creating distinctive image of our product in mind of customers as compare to competitors. Marketing Strategy Our company use market diversification strategy. Distribution Patterns. And pop up ads on more used web sites. Moreover we link our site with some sports. Most scissor jacks are similar in design, consisting of four main members driven by a power screw. A scissor jack is operated simply by turning a small crank that is inserted into one end of the scissor jack. This crank is usually "Z" shaped.

The end fits into a ring hole mounted on the end of the screw, which is the object of force on the scissor jack. When this crank is turned, the screw turns, and this raises the jack. The screw acts like a gear mechanism.

Hydraulic Jack Final Project

It has teeth the screw thread , which turn and move the two arms, producing work. Just by turning this screw thread, the scissor jack can lift a vehicle that is several thousand pounds. Bumper jacks: They were used earlier and are not prevalent nowadays.

In some cases, a damaged hydraulic line or hose can cause complete loss of position. This will not happen with Screw Jacks since the primary lifting mechanism acme thread is inherently self-locking i. Jacks commonly operate for many years in these environments where hydraulic cylinders would simply not survive the fluctuating temperatures and gritty conditions without frequent breakdown.

Screw type mechanical jacks were very common for jeeps and trucks of World War II vintage.

With the industrial revolution of the late 18th and 19th centuries came the first use of screws in machine tools, via English inventors such as John Wilkinson and Henry Maudsley. During the early s in Coaticook, a small town near Quebec, a year- old inventor named Frank Henry Sleeper designed a lifting jack.

The device was efficient, reliable and easy to operate. It was used in the construction of bridges, but mostly by the railroad industry, where it was able to lift locomotives and railway cars. The idea was based on the familiar lever and fulcrum principle and he needed someone to manufacture it Since then the product has evolved to push, pull, lift, lower and position loads of anything from a few kilos to hundreds of tonnes.

One of the biggest single screw jacks made to date is a special Power Jacks E-Series unit that is rated for tonnes even in earthquake conditions for the nuclear industry. Also the common jack having small base is unable to provide proper support on uneven surface esp. We endeavor to develop a scissor jack such that it is cost effective, having a long life and can be handled roughly. They do this by acting on the object they are lifting in a diagonal manner; the lift on the right side lifts the object from its left side and vice versa.

This allows the user to store the jack when it is not in use with the diagonal beams flat and to expand it when it is needed. In order to work, the distance from the loaded point to the cross point must be the same as the distance from the cross point to the ground.

This ensures that weight is distributed equally throughout the scissor lift beams. Scissor lifts for lifting cars can be powered electrically, hydraulically and of course mechanically.

On the other end of the spectrum, industrial scissor lifts that people stand on are often powered by diesel, although electrical options do exist. A single scissor lift has just two crossbeams and one "x. On the other hand, multiple lifts have beams crossing each other, and then attaching to more beams that go the opposite direction.

This allows the scissor lift to rise higher. The four metal pieces are all connected at the corners with a bolt that allows the corners to swivel. A screw thread runs across this assembly and through the corners. As the screw thread is turned, the jack arms travel across it and collapse or come together, forming a straight line when closed.

Then, moving back the other way, they raise and come together. When opened, the four metal arms contract together, coming together at the middle, raising the jack.

When closed, the arms spread back apart and the jack closes or flattens out again. As the screw section is turned, two ends of the jack move closer together. Because the gears of the screw are pushing up the arms, the amount of force being applied is multiplied. It takes a very small amount of force to turn the crank handle, yet that action causes the brace arms to slide across and together. As this happens the arms extend upward.

The car's gravitational weight is not enough to prevent the jack from opening or to stop the screw from turning, since it is not applying force directly to it. If you were to put pressure directly on the crank, or lean your weight against the crank, the person would not be able to turn it, even though your weight is a small percentage of cars. The entire frame of the scissor jack consists of links top and bottom , base frame and support frame.

The frame is manufactured by sheet metal processes and forming by low-medium carbon steel. Power screws are used to convert rotary motion in to translational motion. It is also called translational screw. They find use in machines such as universal tensile testing machines, machine tools, automotive jacks, vises; aircraft flap extenders, trench braces, linear actuators, adjustable floor posts, micrometers, and C-clamps.

A screw thread is formed by cutting a continuous helical groove around the cylinder. These grooves are cut either left hand or right hand. The majority of screws are tightened by clockwise rotation, which is termed a right-hand thread. Screws with left-hand threads are used in exceptional cases. For example, anticlockwise forces are applied to the screw which would work to undo a right-hand thread , a left-hand- threaded screw would be an appropriate choice.

Power screws are typically made from carbon steel, alloy steel, or stainless steel and they are usually used with bronze, plastic, or steel mating nuts. Bronze and plastic nuts are popular for There are important terms and figures that need to be understood before designing power screws: For single thread screw, lead is equal to pitch. Helix Angle: They are ideal for replacing hydraulic and pneumatic drive systems as they require no compressors, pumps, piping, filters, tanks, valves or any other support items required by these systems.

Also, screws don't leak so there are no problems with seals which are so common to hydraulic and pneumatic systems. The work presented herein is mainly divided into the three chapters. The first chapter introduces the concrete benching mixing machine with problem formulation and provides motivation for the project. The second chapter presents the current state of mixing machine research as presented in the form of scientific literature review.

A hydraulic jack is a device used to lift heavy loads.


The device itself is light, compact and portable, but is capable of exerting great force. A hydraulic jack is a jack that uses a liquid to push against a piston. The principle states that pressure in a closed container is the same at all points. If there are two cylinders connected, applying force to the smaller cylinder will result in the same amount of pressure in the larger cylinder.

However, since the larger cylinder has more area, the resulting force will be greater.
