Power
Numerous forklifts are made to run on propane gas. Propane-powered forklifts are very easy to refill. The gas is stored in a pressurized tank on the truck's back. The propane is pushed into the engine, where it is converted into vapor and then the vapor mixes with air. The throttle of the forklift is utilized to be able to control the flow of vapor. A spark plug ignites the air and vapor mixture producing pressure that moves the pistons. The pistons power the hydraulic pump and turn the wheels.
Since the kinds of forklifts which are powered by propane are clean burning and have low emissions, they are suitable to be utilized inside warehouses and other buildings.
Hydraulics
The hydraulic system of the forklift is what enables it to raise and move really heavy things from location to location. A pump, tubes and cylinders make up the hydraulic system. The pump forces dense fluid in the tubing and into the cylinders. The build up of pressure pushes a piston, that lifts the forks. When the forks are lowered by the operator, the hydraulic fluid flows out of the cylinders and back in the pump.
Steering
Where maneuverability is required, propane forklifts are the most suitable. Not like a car, a forklift utilizes its rear wheels to pivot, that enables the forklift to rapidly turn on a tight radius.
