Power
Numerous forklifts are made to run on propane gas. Propane-powered forklifts are 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 combines with air. The forklift throttle is used to control the vapor flow. A spark plug fires up the vapor and air mixture producing pressure that makes the pistons move. The pistons run the hydraulic pump and turn the wheels.
As the kinds of forklifts that are operated by propane are clean burning and have low emissions, they are best to be utilized inside other buildings and warehouses.
Hydraulics
The forklift's hydraulic system is what allows it to raise and move really heavy stuff from place to place. 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, that 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 a car, a forklift uses its rear wheels to turn, which enables the forklift to pivot fast on a tight radius.
