Power
There are many types of forklifts that are operated by propane gas. Propane-powered forklifts are really 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 mixes with air. The throttle of the forklift is used to be able to control the vapor flow. A spark plug ignites the mix of vapor and air producing pressure that makes the pistons move. The pistons run the hydraulic pump and turn the wheels.

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

Hydraulics
The hydraulic system of the forklift is what allows it to raise and transport very heavy objects 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 pressure build up pushes a piston, which raises the forks. When the operator lowers the forks, the hydraulic fluid flows out of the cylinders and back into the pump.

Steering
Propane forklifts work well where maneuverability is needed. Unlike an automobile, a forklift uses its back wheels to turn, which enables the forklift to pivot quickly on a tight radius.
