Power
There are many kinds of forklifts which are powered by propane gas. Forklifts which utilize propane are simple to refill. The gas is stored in a pressurized tank on the rear of the truck. The propane is pushed into the engine, where it is converted into vapor and the vapor mixes with air. The throttle of the forklift is utilized to be able to control the vapor flow. A spark plug ignites the vapor and air mixture producing pressure that makes the pistons move. The pistons turn the wheels and run the hydraulic pump.
Forklifts that utilize propane are recommended for use within warehouses and other buildings because they are clean burning with low emissions.
Hydraulics
What enables a forklift to raise and move heavy things from one location to another is the hydraulic system. A pump, tubes and cylinders make up the hydraulic system. The pump forces dense fluid through the tubing and into the cylinders. The pressure build up pushes a piston, which lifts the forks. When the operator lowers the forks, the hydraulic fluid flows out of the cylinders and back into the pump.
Steering
Where maneuverability is necessary, propane forklifts are the most suitable. Not like a car, a forklift utilizes its rear wheels to turn, which enables the forklift to quickly turn on a tight radius.
