Hydraulic Pump, Valves and Cylinders
Hydraulic Pumps, Valves and Cylinders - Liquid propane cylinders are found on numerous forklifts. Several facilities are able to refuel their own propane cylinders, however, the majority will have their cylinders refilled somewhere else and brought to their office instead. Whenever a lift truck runs out of fuel, the cylinders are changed. Some cautions and training is considered necessary when dealing with propane since it is a highly flammable material.
Personal Protective Equipment, otherwise known as PPE, must be worn prior to changing or filling a forklift cylinder. As liquid propane is very cold, it can result in burns if it comes into contact with the skin. Always putting on thick leather gloves would help protect hands. Goggles or several approved eyewear along with a face shield is likewise very recommended. Having a fire extinguished close at hand is likewise suggested before the refuelling process begins.
Ensure the lift truck is turned off previous to starting and extinguish any open flames or cigarettes in the area. Look for the fill valve on the cylinder and take out the protective plastic cover, then firmly attach the fill line to the fill valve. When the fill line is in place, cautiously open the bleed valve. This will be a small round knob on the cylinder which is usually brass coloured. A hissing sound could escape when the valve is open and this is normal so long as it is just air being vented and not actual propane.
Open the fill valve on the fill line extremely slowly, listening for whatever leaks around the connection point. Once sure there are no leaks, the valve can then be opened further. The sound of propane entering the tank should be easy to hear. Never leave the tank unattended when refuelling and watch the bleeder valve throughout the method. A spray of white propane gas will emit from the bleeder valve as soon as the tank is full. Turn the fill valve off totally and next close the bleeder valve. Very gradually and cautiously 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. Put back the protective cap on the fill valve. Double check all valves are entirely closed. The tank is now ready and full to utilize.
