Raw Materials
The body, cab, boom and frame of a telescoping boom rough terrain forklift are normally manufactured by a forklift manufacturer. The most common material used for these subassemblies is steel, because of its incredible strength. Sometimes aluminum or steel forgings are also used. It is common for non-metallic materials such as nylon plastic blocks to be utilized as guides within the boom assembly. The other components are typically purchased as finished products and the forklift manufacturer installs them.
Pre-assembled purchased products may consist of several of the following: transmission, seat, engine, axles, tires, wheels and hoses, backup-alarm, lights, gauges and hydraulic cylinders. Most often, some materials such as the hydraulic fluid and fuel and lubricants are purchased in bulk. These liquids are added as needed once the equipment 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 narrow and long design which has a set of wheels at the front of the model and another set situated towards the rear of the machine. The model's boom is mounted at the forklift's back off of a pivot feature that is elevated several feet above the frame's level. Usually, the cab is mounted on the left-hand side of the frame structure. Typically, the bottom half of the cab is low and situated 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 engine and the transmission are mounted within the frame.
Beyond this basic configuration, various manufacturers have contributed to their own unique design. On the market these days, there are numerous options available. Certain models of forklifts use a single hydraulic cylinder to be able to raise the boom, and other units make use of 2 cylinders. Several units make use of a side-to-side hydraulic frame leveling capability. This 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. For instance, this is used 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 popular design feature capable of swinging both right and left up to 45 degrees, which increases the precise load positioning.
