Raw Materials
The telescoping boom rough terrain forklift's body, cab, frame and boom are normally produced by a forklift maker. Steel is the most common materials utilized to make these because they have incredible strength. At times aluminum or steel forgings are used as well. It is common for non-metallic materials such as nylon plastic blocks to be utilized as guides within the boom assembly. The other parts are normally bought as finished products and the forklift maker installs them.
Some of the pre-assembled purchased products consist of the transmission, seat, axles, engine, tires, wheels and hoses, lights, back-up alarms, hydraulic cylinders and gauges. Normally, certain materials such as the fuel and lubricants and hydraulic fluids are purchased in bulk. These liquids are added as required when the machine is assembled and has passed the rigorous 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 unit and another set situated towards the back of the machine. The model's boom is mounted at the forklift's back 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. Normally, the cab's bottom half is low and located between the tires. The hydraulic fuel tank and the 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 in the frame.
Different manufacturers have contributed their own unique designs beyond this basic configuration. Today, there are many different options available on the market. Certain models of forklifts make use of a single hydraulic cylinder in order to elevate the boom, and other models use 2 cylinders. Some models use a side-to-side hydraulic frame leveling capability. This feature allows 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 utilized 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.
Fork attachments are another common design feature capable of swinging both right and left up to 45 degrees, that improves the accurate load positioning.
