For most of indoor applications, a forklift is operated with the use of cushioned tires that mean they are made out of solid rubber tires. The pneumatic type of tires is truly the best alternative for outdoor applications. Pneumatic tires are common for heavy cargo and can be utilized on dirt roads and on asphalt surfaces.
Propane powered lift trucks are believed 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 properly tuned or maintained, then the propane powered engine could emit carbon monoxide or CO, along with other caustic oxides of nitrogen. Any internal engine which is not in optional working form can result in a similar situation. These gases that are produced could be really harmful in confined or incorrectly ventilated spaces.
Propane models emit less harmful gases compared to gasoline and diesel powered lift trucks. Propane's chemical structure is rather simple. As it is a gas, propane mixes well with air, as opposed to diesel or gasoline and burns at a low temperature. Caustic oxides of nitrogen created during propane combustion in the engine are a lot less than those emitted by a diesel or gas engine. Thus, a propane lift truck's engine normally lasts much longer compared to a diesel or gasoline powered forklift model.
With an internal combustion engine, air is sucked into it from the surrounding area. This air is what causes the fuel to burn. A 60 horse-power forklift has to breath in 5000 cubic feet of air for every minute in order to work. Before operation, it is recommended to switch on a propane lift truck outside and allow it warm up for a bit. This is due to the carbon monoxide emissions as they read higher from a cold propane-powered engine or machine and become less intoxicating once the equipment has had a chance to warm up.
Electric lift trucks do not get used outdoors in the rain since it is feared the rain could damage the battery. A dangerous situation can happen because an electric forklift can short out because of rainwater getting in.
Propane forklifts however work well in the rain. The propane is stored in sealed tanks that are positioned on the rear of the lift truck. This means there is no chance of a rainstorm interrupting the work of an operator. Propane lift trucks are really versatile and can be used both for outdoor and indoor applications. Diesel and gasoline powered forklifts could suffocate you accidentally with dangerous gases if they are used inside. A correctly tuned up and well maintained forklift is a great way to safely and effectively handle your loads.
