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 in a pressurized tank on the rear 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 be able to control the vapor flow. A spark plug ignites the mix of vapor and air creating pressure which moves the pistons. The pistons turn the wheels and run the hydraulic pump.

Since the types of forklifts that are powered by propane are clean burning and have low emissions, they are best to be utilized inside other buildings and warehouses.

Hydraulics
What enables a forklift to raise and transport 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 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 required, propane forklifts are the most suitable. Not like an automobile, a forklift makes use of its rear wheels to turn, that allows the forklift to pivot fast on a tight radius.
