Raw Materials
The cab, body, boom and frame of a telescoping boom rough terrain forklift are generally manufactured by a lift truck manufacturer. The most common material for these subassemblies is steel, due to its amazing strength. Sometimes aluminum or steel forgings are also utilized. It is common for non-metallic materials like for example nylon plastic blocks to be utilized as guides in the boom assembly. The other parts are typically bought as finished products and the forklift manufacturer installs them.
Pre-assembled bought products can include some of the following: transmission, seat, axles, engine, hoses, tires and wheels, lights, back-up alarms, hydraulic cylinders and gauges. Most often, some materials like the fuel and lubricants and hydraulic fluids are bought in bulk. These liquids are added as required when the machine is assembled and has passed the rigorous testing sessions.
Design
The common design that is most typical of telescoping boom rough terrain forklifts is a long and narrow design that has a set of wheels at the front of the model and another set situated towards the back of the machinery. The unit's boom is mounted at the forklift's rear off of a pivot feature which is raised several feet above the level of the frame. Usually, the cab is mounted on the left-hand side of the frame structure. Typically, the cab's bottom half is low and located between the tires. The fuel tank and the hydraulic fuel tank are mounted on the right-hand side, opposite the cab. Along the vehicle's center-line, the engine and the transmission are mounted inside the frame.
Beyond this basic configuration, different manufacturers have contributed to their own unique design. On the market now, there are numerous options available. Some models of forklifts make use of a single hydraulic cylinder in order to elevate the boom, and other models utilize 2 cylinders. Some units use a side-to-side hydraulic frame leveling capability. This particular feature enables the frame to tilt up to 10 degrees relative to the axles in order to allow the machine to compensate for extreme axle articulation. Like for instance, this is utilized when the tires on one side of the lift truck are located down in a rut and the tires on the other side of the equipment are up, located on a mound of dirt.
One more popular design feature comprises fork attachments which are capable of swinging up to 45 degrees both left and right, in order to enable accurate load positioning.
