Analysis and Fabrication of Remote Control Lifting Jack

With the increasing levels of technology, the efforts being put to produce any kind of work has
been continuously decreasing. The efforts required in achieving the desired output can be
effectively and economically be decreased by the implementation of better designs.
Power screws are used to convert rotary motion into translatory motion. A screw jack is an
example of a power screw in which a small force applied in a horizontal plane is used to raise or
lower a large load. The prin ....etc

Cylinder Blind End Area (in square inches):

PI x (Cylinder Radius)2

Example: What is the area of a 6 diameter cylinder?

Diameter = 6
Radius is 1/2 of diameter = 3
Radius2 = 3 x 3 = 9

x (Cylinder Radius)2 = 3.14 x (3)2 = 3.14 x 9 = 28.26 square inches



Cylinder Rod End Area (in square inches):

Blind End Area - Rod Area

Example: What is the rod end area of a 6 diameter cylinder which has a 3 diameter rod?

Cylinder Blind End Area = 28.26 square inches
Rod Diameter = 3
Radius is 1/2 of rod diameter = 1.5
Radius2 = 1.5 x 1.5 ....etc

mechanical engg seminar topic on hydraulic excavator free download

Excavator: is an engineering vehicle consisting of an articulated arm (boom, stick), bucket and cab mounted on a pivot (a rotating platform, like a Lazy Susan) atop an undercarriage with tracks or wheels. Their design is a natural progression from the steam shovel.
Excavators are used in many ways:
- Digging of trenches, holes, foundations
- Material handling
- Brush cutting with hydraulic attachments
- Demolition
- General grading/landscaping
- Heavy lift, e.g. lifting ....etc

A hydraulic intensifier is a hydraulic machine for transforming hydraulic power at low pressure into a reduced volume at higher pressure.

Operation

Such a machine may be constructed by mechanically connecting two pistons, each working in a separate cylinder of a different diameter. As the pistons are mechanically linked, their force and stroke length are the same. If the diameters are different, the hydraulic pressure in each cylinder will vary in the same ratio as their areas: the smaller piston giving rise to a higher pressure. As the p ....etc

This invention relates to a device for automatically crushing cans.

The principal object of this invention is to provide a device which will automatically feed cans to a crushing apparatus and crush the cans one by one in sequential order so that the device may be left substantially unattended.

Another object of this invention is to provide a device having a can feeding chute which is arranged to sequentially feed unitary cans to a can crushing chamber and to provide a reciprocating piston within the chamber which is arranged to sequentia ....etc

syringe hydraulic arm ppt download

Hydraulics is used in many applications we see or use every day. The brakes in an automobile or the lift on the bucket of a tractor are two very common applications. We can experiment with simple hydraulics using plastic syringes for cylinders and small plastic tubing for the hydraulic hose. One definition I read for hydraulics was, the movement of pressurized liquids through confined spaces .Like working with gears, pulleys, or levers; a mechanical advantage can be realized by using different size cylinder ....etc

An advantage of making bridges moveable is the lower cost, due to the absence of high piers and long approaches. The principal disadvantage is that the traffic on the bridge must be halted when it is opened for passages. For seldom-used railroad bridges over busy channels, the bridge may be left open and then closed for train passages. For small bridges, bridge movement may be enabled without the need for an engine. Some bridges are operated by the users, especially those with a boat, others by a bridgeman (or bridge tender); a few remotely usi ....etc

MAIN PURPOSE:

The hydraulic jack is a device, which is used to lift heavy loads by applying a lot of small force. It is based on the PASCAL LAW, which states that the pressure intensity is equally transmitted in all directions through a mass of liquid in res

ITS PRINCIPLE OF MAIN OPERATION:

The operating principle of a hydraulic jack can be explained with the aid of the figure, some different parts are considered as a plunger and piston, operating on two cylinders of different diameter, which are interconnected at the b ....etc
