Power
There are numerous types of forklifts which are powered by propane gas. Propane-powered forklifts are easy to refill. The gas is stored in a pressurized tank on the truck's back. The propane is pushed into the engine, where it is converted into vapor and afterward the vapor combines with air. The forklift throttle is used to be able to control the flow of vapor. A spark plug ignites the mix of air and vapor producing pressure which moves the pistons. The pistons power the hydraulic pump and turn the wheels.
Forklifts that utilize propane are suggested for use within warehouses and other buildings because they are clean burning with low emissions.
Hydraulics
The hydraulic system of the forklift is what enables it to raise and move really heavy stuff from place to place. A pump, tubes and cylinders make up the hydraulic system. The pump forces dense fluid in the tubing and into the cylinders. The pressure build up pushes a piston, that raises 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. Unlike a car, a forklift makes use of its rear wheels to turn, which allows the forklift to pivot quickly on a tight radius.
