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 for these subassemblies is steel, due to its incredible strength. Sometimes steel forgings or aluminum are used also. It is common for non-metallic materials like for instance nylon plastic blocks to be used as guides within the boom assembly. The other parts are normally bought as finished products and the forklift manufacturer installs them.
Several of the pre-assembled purchased products consist of the seat, transmission, engine, axles, tires, wheels and hoses, lights, back-up alarms, hydraulic cylinders and gauges. Usually, some materials such as the fuel and lubricants and hydraulic fluids are bought in bulk. These liquids are added as needed once the machine 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 unit and another set located towards the rear of the machinery. The boom portion of the model is mounted at the back of the forklift off of a pivot feature which is raised several feet above the level of the frame. Generally, the cab is mounted on the frame structure's left-hand side. Usually, the cab's bottom half is low and located between the tires. The fuel tank and the hydraulic fuel tank are mounted on the right-hand side, opposite the cab. Along the vehicle's center-line, 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 existing on the market. Certain units of forklifts use a single hydraulic cylinder to be able to raise the boom, and other units use 2 cylinders. Several models 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 so as to allow the machinery to compensate for extreme axle articulation. For instance, this is used 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.
One more popular design feature includes fork attachments which are capable of swinging up to 45 degrees both right and left, in order to allow precise load placement.
