Forklifts, when used in indoor applications, are typically operated on cushioned tires which are made out of solid rubber. The pneumatic type of tires is really the ideal option for outdoor applications. Pneumatic tires can be utilized on asphalt surfaces and on dirt roads and are common for heavy loads.
For the most part, propane powered machinery is believed to be safe. Propane has the reputation for being a clean burning fuel source. If the engine or machinery is not correctly tuned or maintained, then the propane powered engine can emit CO or carbon monoxide, along with other caustic oxides of nitrogen. Any internal engine which is not in optional working form can result in a similar situation. These produced gases can be extremely harmful in incorrectly ventilated or confined spaces.
Compared to diesel and gasoline powered lift trucks, propane units emit less harmful gases. Propane has a simple chemical structure. Since it is a gas, propane mixes really well with air, compared to gasoline or diesel and burns at a low temperature. Corrosive oxides of nitrogen produced during propane combustion in the engine are a lot less than those produced by a gas or diesel engine. Hence, the engine of a propane lift truck usually lasts a lot longer than a diesel or gasoline powered lift truck unit.
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 lift truck must breath in 5000 cubic feet of air for every minute to be able to operate. Prior to operation, it is recommended to switch on a propane forklift outside and let it warm up for a bit. This is because of the carbon monoxide emissions as they read higher from a cold propane-powered engine or machinery and become less potent once the equipment has had a chance to warm up.
It is important to remember that electric or battery powered lift trucks can not be used outdoors in the rain for fear of damaging the battery if they get wet. A dangerous situation could occur as an electric lift truck can short out due to rainwater getting in.
However, propane lift trucks work well in the rain. The propane is stored in the on-board well sealed tanks. This means there is no chance of a rainstorm interrupting an operator's work. Propane lift trucks are really versatile and are capable of being utilized both for outdoor and indoor applications. Gasoline and diesel powered lift trucks could suffocate you accidentally with dangerous gases if they are used inside. A properly tuned up and well maintained lift truck is a great way to safely and effectively handle your loads.
