Brake for Forklift - A brake in which the friction is provided by a set of brake shoes or brake pads that press against a rotating drum shaped unit called a brake drum. There are several specific differences among brake drum types. A "brake drum" is commonly the definition given when 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 exterior of the drum. One more type of brake, known as a "band brake" utilizes a flexible belt or band to wrap round the exterior of the drum. Where the drum is pinched in between two shoes, it could be referred to as a "pinch brake drum." Similar to a standard disc brake, these types of brakes are quite uncommon.
Early brake drums, prior to 1955, required to be consistently modified to be able to compensate for wear of the drum and shoe. "Low pedal" can cause the required adjustments are not performed sufficiently. The motor vehicle can become dangerous and the brakes can become useless if low pedal is mixed together with brake fade.
There are some different Self-Adjusting systems used for braking obtainable these days. They can be classed into two separate categories, the RAI and RAD. RAI systems are built in systems which help the tool recover from overheating. The most popular RAI manufacturers are Bosch, AP, Bendix and Lucas. The most well-known RAD systems comprise AP, Bendix, Ford recovery systems and Volkswagen, VAG.
The self adjusting brake will normally just engage if the lift truck is reversing into a stop. This method of stopping is acceptable for use whereby all wheels utilize brake drums. Disc brakes are used on the front wheels of vehicles today. By working only in reverse it is less likely that the brakes will be applied while hot and the brake drums are expanded. If tweaked while hot, "dragging brakes" can take place, which increases fuel consumption and accelerates wear. A ratchet tool which becomes engaged as the hand brake is set is one more way the self repositioning brakes could work. This means is only suitable in applications where rear brake drums are utilized. When the emergency or parking brake actuator lever goes over a certain 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 base of the drum. It is typically adjusted through a hole on the opposite side of the wheel and this involves going under the forklift along with a flathead screwdriver. It is of utmost importance to move the click wheel properly and adjust each and every wheel evenly. If uneven adjustment occurs, the vehicle may pull to one side during heavy braking. The most effective method to be able to guarantee this tiresome job is completed carefully is to either raise each wheel off the ground and hand spin it while measuring how much force it takes and feeling if the shoes are dragging, or give each one the exact amount of manual clicks and then perform a road test.
