Raw Materials
The cab, body, frame and boom of a telescoping boom rough terrain forklift are normally made by a forklift manufacturer. The most popular material used for these subassemblies is steel, because of its tremendous strength. At times aluminum or steel forgings are also used. It is common for non-metallic materials such as nylon plastic blocks to be utilized as guides in the boom assembly. The other components are usually bought as finished products and the lift truck maker installs them.
Some of the pre-assembled purchased products consist of the transmission, seat, engine, axles, wheels, hoses and tires, lights, back-up alarms, hydraulic cylinders and gauges. Usually, certain materials such as the fuel and lubricants and hydraulic fluids are bought in bulk. These liquids are added as required once the equipment is assembled and has passed the meticulous testing sessions.
Design
The narrow and long 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 located towards the back of the equipment. The unit's boom is mounted at the rear of the forklift off of a pivot feature that is elevated a few feet above the level of the frame. Generally, the cab is mounted on the frame structure's left-hand side. Usually, the bottom half of the cab is low and situated between the tires. The fuel tank and the hydraulic fuel tank are mounted on the right-hand side, opposite the cab. Along the center-line of the vehicle, the transmission and the engine are mounted inside the frame.
Beyond this basic configuration, different manufacturers have contributed to their own unique design. On the market nowadays, there are many different options available. Certain units of forklifts use a single hydraulic cylinder to be able to elevate the boom, and other units make use of 2 cylinders. Several units use a side-to-side hydraulic frame leveling capability. This particular feature allows the frame to tilt up to 10 degrees relative to the axles in order to enable the machine to compensate for extreme axle articulation. This is used for example, when the tires on one side of the forklift are situated down in a rut and the tires on the other side of the machine are up, situated on a mound of dirt.
Another popular design feature includes fork attachments which are capable of swinging up to 45 degrees both left and right, in order to enable precise load placement.
