Power
There are numerous kinds of forklifts which are operated by propane gas. Forklifts that utilize propane are easy to refill. The gas is stored in a pressurized tank on the truck's rear. The propane is pushed into the engine, where it is converted into vapor and the vapor combines with air. The throttle of the forklift is used to be able to control the vapor flow. A spark plug ignites the mixture of air and vapor producing pressure which makes the pistons move. The pistons run the hydraulic pump and turn the wheels.
Forklifts that utilize propane are suggested for use within other buildings and warehouses since they are clean burning with low emissions.
Hydraulics
The hydraulic system of the forklift is what allows it to raise and transport very heavy stuff from location to location. A pump, tubes and cylinders make up the hydraulic system. The pump forces dense fluid in the tubing and into the cylinders. The build up of pressure 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 necessary, propane forklifts are the most suitable. Unlike a car, a forklift makes use of its back wheels to turn, that allows the forklift to turn fast on a tight radius.
