Power
There are numerous kinds of forklifts which are operated by propane gas. Forklifts which use propane are simple to refill. The gas is stored inside a pressurized tank on the truck's rear. The propane is pushed into the engine, where it is converted into vapor and then the vapor combines with air. The throttle of the forklift is used to be able to control the vapor flow. A spark plug ignites the air and vapor mixture creating 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 best to be utilized in other buildings and warehouses.

Hydraulics
What enables a forklift to lift and move heavy objects from one location to another is the hydraulic system. Cylinders, a pump and tubes 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 raises 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 an automobile, a forklift utilizes its rear wheels to turn, that allows the forklift to quickly turn on a tight radius.
