Power
There are many kinds of forklifts which are powered by propane gas. Propane-powered forklifts are simple to refill. The gas is stored inside a pressurized tank on the truck's back. 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 fires up the vapor and air mixture producing pressure that makes the pistons move. The pistons power the hydraulic pump and turn the wheels.

Because the kinds of forklifts that are powered by propane have low emissions and are clean burning, 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 very heavy things from location to location. 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 in the pump.

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