Raw Materials
The cab, body, boom and frame of a telescoping boom rough terrain forklift are usually made by a lift truck manufacturer. The most popular material for these subassemblies is steel, because of its amazing strength. At times steel forgings or aluminum are also used. It is common for non-metallic materials such as nylon plastic blocks to be used as guides in the boom assembly. The other parts are typically purchased as finished products and the lift truck maker installs them.
Some of the pre-assembled bought products consist of the transmission, seat, engine, axles, tires, wheels and hoses, backup-alarm, lights, hydraulic cylinders and gauges. Normally, certain materials like the fuel and lubricants and hydraulic fluids are purchased in bulk. These liquids are added as needed when the machinery is assembled and has passed the meticulous testing sessions.
Design
The long and narrow design of the telescoping boom rough terrain forklift is most common, with a set of wheels at the front of the model and another set situated towards the back of the equipment. The boom portion of the model is mounted at the rear of the forklift off of a pivot feature that is elevated a few feet above the frame's level. Generally, the cab is mounted on the left-hand side of the frame structure. Usually, the cab's bottom half 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.
Various manufacturers have contributed their own unique designs beyond this basic configuration. These days, there are numerous options existing on the market. Some models of forklifts make use of a single hydraulic cylinder to be able to elevate the boom, and other models use 2 cylinders. Some units make use of a side-to-side hydraulic frame leveling capability. This feature allows the frame to tilt up to 10 degrees relative to the axles so as to enable 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 situated down in a rut and the tires on the other side of the equipment are up, located on a mound of dirt.
Fork attachments are one more common design feature capable of swinging both right and left up to 45 degrees, that improves the accurate load positioning.
