Hydraulic Pumps, Valves and Cylinders
Hydraulic Pump, Valves and Cylinders - Liquid propane cylinders are used on numerous forklifts. Some facilities are able to refuel their own propane cylinders, however, nearly all would have their cylinders refilled in a different place and delivered to their office instead. If a lift truck runs out of fuel, the cylinders are changed. Several cautions and training is essential when dealing with propane because it is a very flammable substance.
Personal Protective Equipment, otherwise known as PPE, must be worn previous to filling or changing a lift truck cylinder. As liquid propane is very cold, it can cause burns if it comes into skin contact. At all times having on thick leather gloves would help protect hands. Goggles or several approved eyewear together with a face shield is also extremely recommended. Having a fire extinguished within the immediate vicinity is also recommended before the refuelling method starts.
Make certain that the surroundings are safe from whatever lit cigarettes or open fires. Find the fill valve on the cylinder and take out the cover. Then you could attach the fill line to the fill valve. As soon as the fill line is in place, carefully open the bleed valve. This would be a small circular knob on the cylinder which is often brass coloured. A hissing sound may escape when the valve is open and this is normal as long as it is only air being vented and not actual propane.
Open the fill valve on the fill line really unhurriedly, listening for whichever leaks around the connection point. When positive there are no leaks, the valve could then be opened more. The sound of propane entering the tank must be easy to hear. By no means leave the tank unattended when refuelling and look at the bleeder valve throughout the method. A spray of white propane gas will emit from the bleeder valve when the tank is full. Turn the fill valve off completely and next close the bleeder valve. Very gradually and carefully take out the fill line from the tank. Watch for whichever extra gas caught in the coupling which would be expelled when the seal is broken. It must only be a small quantity of gas and is normal. Replace the protective cover on the fill valve. Double check all valves are entirely closed. The tank is now ready and full to utilize.
