For most of indoor operations, a lift truck is operated with the use of cushioned tires that mean they are made out of solid rubber tires. The pneumatic style of tires is truly the best choice outdoors. Pneumatic tires could be used on dirt roads and on asphalt surfaces and are common for heavy cargo.
Propane powered forklifts are trusted to be safe for the most part and has a reputation for being a clean burning fuel source. If the engine or equipment is not maintained or tuned up properly, then the propane powered engine could emit carbon monoxide or CO, along with other caustic oxides of nitrogen. Any internal engine that is not in optional running form may result in a similar situation. These produced gases can be extremely harmful within confined or incorrectly ventilated spaces.
Compared to diesel and gasoline powered forklifts, propane units emit less harmful gases. Propane has a simple chemical structure. Since it is a gas, propane burns at a low temperature and mixes really well with air, compared to diesel or gasoline. Caustic oxides of nitrogen produced during propane combustion in the engine are less than those emitted by a gas or diesel engine. Thus, a propane lift truck's engine typically lasts much longer than a diesel or gasoline powered forklift model.
With an IC engine, air is sucked into it from the surrounding area. This air is what makes the fuel burn. A 60 horse-power lift truck must breath in 5000 cubic feet of air per minute to be able to operate. Prior to operation, it is recommended to switch on a propane forklift outside and allow it warm up for a bit. This is due to the carbon monoxide emissions since they read higher from a cold propane-powered engine or machine and become less potent once the machine has had a chance to warm up.
Electric lift trucks are not used outdoors in the rain because it is feared the rain may damage the battery. A dangerous situation can happen because an electric lift truck could short out because of rainwater getting in.
Propane lift trucks on the other hand work well in the rain. The propane is stored in sealed tanks which are positioned on the rear of the lift truck. This means there is no chance of a rainstorm interrupting a driver's work. Propane forklifts are really versatile and are capable of being used both outdoors and indoors. Diesel and gasoline powered forklifts can accidentally suffocate you with harmful gases if they are used inside. A correctly tuned up and well maintained forklift is a great way to effectively and safely handle your loads.
