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 some specific differences between brake drum types. A "brake drum" is commonly the definition given if shoes press on the inner surface of the drum. A "clasp brake" is the term used in order to describe whenever shoes press against the outside of the drum. Another kind of brake, called a "band brake" utilizes a flexible belt or band to wrap around the exterior of the drum. Where the drum is pinched in between two shoes, it could be known as a "pinch brake drum." Similar to a typical disc brake, these kinds of brakes are quite uncommon.
Old brake drums, prior to nineteen ninety five, required to be constantly adjusted so as to compensate for wear of the shoe and drum. "Low pedal" can cause the needed adjustments are not done sufficiently. The vehicle can become hazardous and the brakes could become useless when low pedal is mixed along with brake fade.
There are various Self Adjusting Brake Systems available, and they can be categorized within two main types, RAI and RAD. RAI systems have built in tools that avoid the systems to recover when the brake is overheating. The most recognized RAI makers are AP, Bendix, Lucas, and Bosch. The most well-known RAD systems include Ford recovery systems, Volkswagen, VAG, AP and Bendix.
The self adjusting brake would typically just engage if the lift truck is reversing into a stop. This method of stopping is acceptable for use where all wheels use brake drums. Disc brakes are utilized on the front wheels of vehicles nowadays. By operating only in reverse it is less likely that the brakes would be adjusted while hot and the brake drums are expanded. If adapted while hot, "dragging brakes" could happen, which increases fuel intake and accelerates wear. A ratchet tool that becomes engaged as the hand brake is set is one more way the self adjusting brakes may function. This means is just appropriate in applications where rear brake drums are utilized. Whenever the emergency or parking brake actuator lever goes over a certain amount of travel, the ratchet improvements 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 via a hole on the other side of the wheel and this requires going under the lift truck utilizing a flathead screwdriver. It is of utmost importance to be able to move the click wheel correctly and adjust each and every wheel equally. If unequal adjustment takes place, the vehicle could pull to one side during heavy braking. The most effective method to ensure this tedious job is done carefully is to either lift every 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 everyeach and every one the same amount of manual clicks and then do a road test.
