For most of indoor operations, a lift truck is operated with the use of cushioned tires which mean they are made out of solid rubber tires. The pneumatic type of tires is really the perfect alternative outdoors. Pneumatic tires are common for heavy loads and can be utilized on asphalt surfaces and on dirt roads.
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 machine or engine is not correctly maintained or tuned, then the propane powered engine could emit CO or carbon monoxide, along with other corrosive oxides of nitrogen. Any internal engine that is not in optional running form could have a similar situation happen. These gases which are emitted could be extremely harmful in incorrectly ventilated or confined spaces.
Propane models produce less harmful gases compared to diesel and gasoline powered forklifts. Propane's chemical structure is rather simple. Because it is a gas, propane burns at a low temperature and mixes really well with air, as opposed to gasoline or diesel. Caustic oxides of nitrogen produced during propane combustion in the engine are less than those emitted by a diesel or gas engine. Thus, a propane forklift's engine normally lasts a lot longer compared to a diesel or gasoline powered lift truck unit.
Internal combustion engines work by sucking in air from the surrounding area. This air reacts with the fuel causing it to burn. A 60 horse-power lift truck has to breath in 5000 cubic feet of air for every minute in order to work. Before operation, it is better 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 when the equipment has had a chance to warm up.
It is important to remember that electric or battery powered lift trucks could not be used outdoors in the rain for fear of battery damage if they get wet. A dangerous situation could occur as an electric forklift can short out due to rainwater getting in.
On the other hand, propane forklifts work really well in the rain. The propane is stored in the on-board well sealed tanks. This means there is no possibility of a rainstorm interrupting a driver's work. Propane lift trucks are really versatile and can be utilized both for indoor and outdoor operations. Gasoline and diesel powered lift trucks can accidentally suffocate you with harmful gases if they are used inside. A well maintained and properly tuned up lift truck is a good way to effectively and safely handle your loads.
