Raw Materials
The telescoping boom rough terrain forklift's cab, body, frame and boom are normally made by a forklift maker. Steel is the most common materials used to make these since they have incredible strength. At times steel forgings or aluminum 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 parts are normally bought as finished products and the forklift manufacturer installs them.
Several of the pre-assembled purchased products consist of the transmission, seat, engine, axles, tires, wheels and hoses, lights, back-up alarms, hydraulic cylinders and gauges. Usually, some materials like the hydraulic fluid and fuel and lubricants are bought in bulk. These liquids are added as needed when the equipment is assembled and has passed the meticulous testing sessions.
Design
The common design that is most standard of telescoping boom rough terrain forklifts is a long and narrow design which has a set of wheels at the front of the unit and another set located towards the back of the machine. The model's boom is mounted at the forklift's back off of a pivot feature which is raised several feet above the frame's level. Generally, the cab is mounted on the frame structure's left-hand side. Normally, the bottom half of the cab is low and located 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 inside the frame.
Beyond this basic configuration, various manufacturers have contributed to their own unique design. On the market these days, there are many different options available. Certain models of forklifts use a single hydraulic cylinder in order to raise the boom, and other units use 2 cylinders. Some models utilize a side-to-side hydraulic frame leveling capability. This particular feature enables the frame to tilt up to 10 degrees relative to the axles in order to allow the equipment 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 equipment are up, situated on a mound of dirt.
Another common design feature includes fork attachments that are capable of swinging up to 45 degrees both left and right, in order to enable accurate load positioning.
