Raw Materials
The cab, body, boom and frame of a telescoping boom rough terrain forklift are generally made by a forklift manufacturer. The most common material for these subassemblies is steel, because of its amazing strength. At times steel forgings or aluminum are used as well. It is common for non-metallic materials like for example nylon plastic blocks to be utilized as guides in the boom assembly. The other components are typically purchased as finished products and the lift truck manufacturer installs them.
Several of the pre-assembled purchased products comprise the transmission, seat, axles, engine, tires, wheels and hoses, backup-alarm, lights, gauges and hydraulic cylinders. Most often, some materials such as the lubricants and hydraulic fluid and fuel are purchased in bulk. These liquids are added as needed once the machine is assembled and has passed the rigorous testing sessions.
Design
The common design which is most typical of telescoping boom rough terrain forklifts is a narrow and long design which has a set of wheels at the front of the model and another set located towards the back of the equipment. The unit's boom is mounted at the forklift's rear off of a pivot feature that is raised several feet above the frame's level. Usually, the cab is mounted on the frame structure's left-hand side. Normally, the bottom half of the cab is low and located between the tires. The fuel tank and the hydraulic fuel tank are mounted opposite the cab on the right-hand side. Along the center-line of the vehicle, the transmission and the engine are mounted in the frame.
Beyond this basic configuration, various manufacturers have contributed to their own unique design. On the market nowadays, there are many different options offered. Certain models of forklifts make use of a single hydraulic cylinder in order to elevate the boom, and other models utilize 2 cylinders. Some units utilize a side-to-side hydraulic frame leveling capability. This particular feature enables the frame to tilt up to 10 degrees relative to the axles so as to allow the machine to compensate for extreme axle articulation. This is used for example, when the tires on one side of the lift truck are situated down in a rut and the tires on the other side of the equipment are up, situated on a mound of dirt.
Fork attachments are another common design feature capable of swinging both right and left up to 45 degrees, that improves the precise load placement.
