Power
There are many types of forklifts that are operated by propane gas. Propane-powered forklifts are simple 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 then the vapor mixes with air. The forklift throttle is utilized to be able to control the flow of vapor. A spark plug ignites the vapor and air mixture producing pressure that moves the pistons. The pistons power the hydraulic pump and turn the wheels.

Since the kinds of forklifts which are operated by propane are clean burning and have low emissions, they are best to be utilized within other buildings and warehouses.

Hydraulics
The hydraulic system of the forklift is what allows it to lift and transport really heavy stuff from place to place. 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 operator lowers the forks, the hydraulic fluid flows out of the cylinders and back into the pump.

Steering
Where maneuverability is needed, propane forklifts are the most suitable. Not like an automobile, a forklift uses its rear wheels to turn, that enables the forklift to quickly turn on a tight radius.
