For convenient maintenance of the car is nice to have in the garage the car lift. Making it from the hydraulic cylinder of a loader or other machinery, it can significantly save free space, as virtually all of the technical component of the device hidden under the ground. The piston lifts the proposed design allows you to rotate the raised vehicle in any direction without dropping it down.
- hydraulic cylinder for forklift with the stroke of 1.1-2 m;
- steel pipe of large diameter;
- oil pump driven by an electric motor;
- profiled tube 80×80 mm;
- area 60×60 mm;
- high-pressure hoses, air hoses.
Review of device and manufacturing process of forklift truck
Underground lifting part of the device is a vertically concreted in the hole the drill dug a large pipe. It serves as a guide. It is located in the hydraulic cylinder from the lift.
Since the rod of the hydraulic cylinder is thin enough, then above it is another plugged on top of the pipe. She slides along the rail, which eliminates distortion while lifting.
That is, the hydraulic cylinder is located inside between the pipes and throws them. The internal ones are performing the function of a stock, it is possible to weld from oxygen. After that, the stock grind grinder, as the cylinders are quite rough. If the diameter of the outer and inner tube do not match, and between them you get a big gap, then the outer can weld it about 30 cm over a thin tube with machined inner seam. In this case, the rod will slide through it. He definitely will not get stuck or warp. If the cylinder has a thick stock, you can just pour into the well and not to use any pipe.
Connected to the hydraulic cylinder 2 hose. As the bottom uses a high-pressure hose. He is laid to an oil pump driven by an electric motor. The second hose connects to the compressor. When pumping oil the hydraulic cylinder raises the lift. When it is necessary to lower, the air is supplied from the compressor to the top of the cylinder, as the weight of the machine is not always enough to squeeze the oil back.
For implementation of such a mechanism is necessary when laying the oil pipe install the 2 tap. One necessary to do the tie-in line for the skimmed oil in a tank, and the second to shut off the oil pump. Before raising the rod, you must first turn off the tap skimmed, and then lift to close and the valve of the pump. In this case, the hydraulic cylinder is not exactly fall under load. Then if you need to lower it, the valve opens the separator, allowing oil to drain back to the tank. In parallel, you will need to pump the pressure up the compressor cylinder, if the weight of the machine will be a little indentation for the stem.
To raise the vehicle, you need to make the thrust pad. It represents the welded coil where you using your fingers 4 fixed beam length of 65 cm from a shaped tube 80×80 mm. For extended 4 used thinner pipe, length 60 cm can be welded from the corner and turned down for easy slip in the profile. The platform is mounted on a sliding rod with a thick finger. This allows it to rotate together with the raised car. At the edges of the rays to cut the threads for the mounting of the plates will abut in the bottom of the car.
Before you lift you want to draw paint lines on the garage floor, which can be factored in. Without them be exactly under the stem will be difficult. Then the rays are diverging and the plate out until it stops at the bottom. Getting 4 points of support included the oil pump and the car rises. It is desirable before using the forklift truck to make it a locking mechanism as in the case of rupture of the hydraulic hoses that go down, that it’s not safe. The stopper should enter between the outer tube and the stem. For its operation need to develop a remote control, so as not to get under the car to install it manually.
