For most of indoor operations, a forklift is operated with the use of cushioned tires which mean they are made out of solid rubber tires. The pneumatic style of tires is the ideal choice outdoors. Pneumatic tires are common for heavy loads and could 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 machine or engine is not maintained or tuned up correctly, then the propane powered engine can produce CO or carbon monoxide, along with other corrosive oxides of nitrogen. Any internal engine which is not in optional working form may have a similar situation happen. These gases which are produced can be very noxious in confined or incorrectly ventilated spaces.
Propane units emit less harmful gases compared to gasoline and diesel powered forklifts. The chemical structure of propane is rather simple. Since it is a gas, propane burns at a low temperature and mixes well with air, compared to gasoline or diesel. Corrosive oxides of nitrogen produced during propane combustion in the engine are less than those produced by a gas or diesel engine. Thus, a propane lift truck's engine typically lasts a lot longer than a gasoline or diesel powered forklift model.
With an internal combustion engine, air is sucked into it from the surrounding area. This air is what makes the fuel burn. A 60 horse-power lift truck needs to breath in 5000 cubic feet of air per minute in order to work. Before operation, it is recommended to switch on a propane forklift outside and let 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 equipment and become less potent once the machine has had a chance to warm up.
Electric lift trucks do not get used outdoors in the rain since it is feared the rain can damage the battery. A dangerous situation can happen as an electric forklift could short out due to rainwater getting in.
Propane lift trucks however work really well in the rain. The propane is stored in sealed tanks that are placed 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 extremely versatile and are capable of being utilized both indoors and outdoors. Diesel and gasoline powered lift trucks can accidentally suffocate you with harmful gases if they are used indoors. A well maintained and correctly tuned up lift truck is a good way to safely and effectively handle your loads.
