Power
There are numerous types of forklifts which are operated by propane gas. Propane-powered forklifts are easy to refill. The gas is stored in a pressurized tank on the back of the truck. The propane is pushed into the engine, where it is converted into vapor and afterward the vapor combines with air. The throttle of the forklift is utilized to control the flow of vapor. A spark plug fires up the vapor and air mixture producing pressure that makes the pistons move. The pistons run the hydraulic pump and turn the wheels.

As the types of forklifts which are operated by propane have low emissions and are clean burning, they are suitable to be utilized in other buildings and warehouses.

Hydraulics
What enables a forklift to raise and transport heavy things from one place to another is the hydraulic system. Tubes, cylinders and a pump make up the hydraulic system. The pump forces dense fluid through 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 needed, propane forklifts are the most suitable. Not like a car, a forklift uses its back wheels to pivot, which allows the forklift to pivot fast on a tight radius.
