Forklift Brake
Forklift Brakes - A brake in which the friction is provided by a set of brake shoes or brake pads which press against a rotating drum unit referred to as a brake drum. There are a few specific differences among brake drum kinds. A "brake drum" is usually the definition given whenever shoes press on the interior surface of the drum. A "clasp brake" is the term utilized to be able to describe if shoes press next to the outside of the drum. Another kind of brake, known as a "band brake" uses a flexible band or belt to wrap round the outside of the drum. If the drum is pinched in between two shoes, it could be referred to as a "pinch brake drum." Like a standard disc brake, these types of brakes are somewhat rare.
Prior to 1955, early brake drums needed constant modification regularly to be able to compensate for shoe and drum wear. "Low pedal" or long brake pedal travel is the dangerous end result if modifications are not executed satisfactorily. The motor vehicle can become dangerous and the brakes can become useless if low pedal is mixed with brake fade.
There are various Self Adjusting Brake Systems available, and they can be categorized within two main types, RAD and RAI. RAI systems have built in devices that avoid the systems to be able to recover if the brake is overheating. The most popular RAI manufacturers are Lucas, Bosch, AP and Bendix. The most famous RAD systems include Bendix, Ford recovery systems, Volkswagen, VAG and AP.
The self adjusting brake will typically just engage when the lift truck is reversing into a stop. This method of stopping is suitable for use whereby all wheels use brake drums. Disc brakes are used on the front wheels of motor vehicles today. By operating only in reverse it is less probable that the brakes will be adjusted while hot and the brake drums are expanded. If adapted while hot, "dragging brakes" can happen, which increases fuel intake and accelerates wear. A ratchet mechanism which becomes engaged as the hand brake is set is another way the self adjusting brakes could work. This means is just suitable in functions where rear brake drums are used. When the emergency or parking brake actuator lever goes over a particular amount of travel, the ratchet developments an adjuster screw and the brake shoes move in the direction of the drum.
There is a manual adjustment knob situated at the bottom of the drum. It is usually adjusted through a hole on the opposite side of the wheel and this requires going beneath the forklift with a flathead screwdriver. It is of utmost significance to be able to move the click wheel correctly and adjust every wheel equally. If uneven adjustment takes place, the vehicle could pull to one side during heavy braking. The most efficient method so as to make certain this tiresome job is completed carefully is to either raise each wheel off the ground and spin it by hand while measuring how much force it takes and feeling if the shoes are dragging, or give every\each and every one the exact amount of manual clicks and then do a road test.
