Forklift Brakes - A brake wherein the friction is provided by a set of brake shoes or brake pads which press against a rotating drum shaped unit known as a brake drum. There are some particular differences among brake drum types. A "brake drum" is commonly the definition provided whenever shoes press on the inner exterior of the drum. A "clasp brake" is the term used so as to describe whenever shoes press against the exterior of the drum. One more type of brake, called a "band brake" uses a flexible belt or band to wrap round the exterior of the drum. If the drum is pinched in between two shoes, it could be called a "pinch brake drum." Similar to a standard disc brake, these types of brakes are somewhat rare.
Previous to 1955, early brake drums needed constant adjustment periodically in order to compensate for drum and shoe wear. "Low pedal" or long brake pedal travel is the dangerous outcome if adjustments are not carried out satisfactorily. The motor vehicle can become dangerous and the brakes can become ineffective when low pedal is combined along with brake fade.
There are different Self Adjusting Brake Systems offered, and they could be categorized within two main kinds, RAD and RAI. RAI systems have in-built equipments which prevent the systems to be able to recover when the brake is overheating. The most recognized RAI makers are Lucas, Bosch, AP and Bendix. The most well-known RAD systems comprise Ford recovery systems, Volkswagen, VAG, AP and Bendix.
The self adjusting brake would normally just engage whenever the lift truck is reversing into a stop. This method of stopping is satisfactory for use where all wheels utilize brake drums. Disc brakes are utilized on the front wheels of motor vehicles nowadays. By operating only in reverse it is less possible that the brakes would be adjusted while hot and the brake drums are expanded. If adapted while hot, "dragging brakes" could happen, which raises 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 could operate. This means is just appropriate in functions where rear brake drums are utilized. When the parking or emergency brake actuator lever goes beyond a specific amount of travel, the ratchet advances an adjuster screw and the brake shoes move in the direction of the drum.
There is a manual adjustment knob located 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 forklift utilizing a flathead screwdriver. It is of utmost importance to move the click wheel properly and tweak every wheel evenly. 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 tedious task is done carefully is to either raise each and 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 each one the same amount of manual clicks and then perform a road test.
