Power
There are many types of forklifts which are operated by propane gas. Propane-powered forklifts are simple to refill. The gas is stored inside a pressurized tank on the truck's rear. The propane is pushed into the engine, where it is converted into vapor and afterward the vapor combines with air. The throttle of the forklift is utilized to control the flow of vapor. A spark plug fires up the mixture of vapor and air creating pressure that makes the pistons move. The pistons power the hydraulic pump and turn the wheels.
Forklifts that use propane are suggested for use inside other buildings and warehouses since they are clean burning with low emissions.
Hydraulics
What allows a forklift to lift and transport heavy objects from one location to another is the hydraulic system. Tubes, cylinders and a pump 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 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 necessary, propane forklifts are the most suitable. Not like an automobile, a forklift utilizes its back wheels to pivot, that enables the forklift to turn quickly on a tight radius.
