Power
Many forklifts are made to run on propane gas. Forklifts that utilize propane 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 the vapor combines with air. The forklift throttle is utilized to be able to control the flow of vapor. A spark plug fires up the air and vapor mixture producing pressure that moves the pistons. The pistons run the hydraulic pump and turn the wheels.
Because the types of forklifts that are powered by propane have low emissions and are clean burning, they are suitable to be used in warehouses and other buildings.
Hydraulics
The forklift's hydraulic system is what allows it to lift and transport very heavy things from location to location. Cylinders, a pump and tubes 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 lifts the forks. When the forks are lowered by the operator, the hydraulic fluid flows out of the cylinders and back into the pump.
Steering
Where maneuverability is needed, propane forklifts are the most suitable. Unlike an automobile, a forklift utilizes its back wheels to pivot, that enables the forklift to quickly turn on a tight radius.
