Forklift Brakes
Forklift Brakes - A brake drum is where the friction is supplied by the brake pads or brake shoes. The shoes or pads press up against the rotating brake drum. There are several different brake drums types with certain specific differences. A "break drum" will normally refer to if either pads or shoes press onto the interior surface of the drum. A "clasp brake" is the term used so as to describe when shoes press against the exterior of the drum. Another type of brake, called a "band brake" utilizes a flexible band or belt to wrap round the outside of the drum. Where the drum is pinched in between two shoes, it can be known as a "pinch brake drum." Similar to a standard disc brake, these kinds of brakes are rather rare.
Early brake drums, before the year 1995, required to be constantly modified in order to compensate for wear of the shoe and drum. "Low pedal" can result if the needed modifications are not carried out sufficiently. The vehicle can become dangerous and the brakes could become useless if low pedal is mixed along with brake fade.
There are various Self Adjusting Brake Systems offered, and they can be categorized within two major kinds, RAD and RAI. RAI systems have inbuilt tools that prevent the systems to be able to recover when the brake is overheating. The most well known RAI makers are Lucas, Bosch, AP and Bendix. The most famous RAD systems comprise Volkswagen, VAG, AP, Bendix and Ford recovery systems.
The self adjusting brake would usually only engage if the lift truck is reversing into a stop. This method of stopping is acceptable for use whereby all wheels use brake drums. Disc brakes are used on the front wheels of vehicles today. By working only in reverse it is less probable that the brakes would be applied while hot and the brake drums are expanded. If adjusted while hot, "dragging brakes" could take place, which increases fuel expenditure and accelerates wear. A ratchet device that becomes engaged as the hand brake is set is one more way the self adjusting brakes could function. This means is just appropriate in applications where rear brake drums are used. Whenever the emergency or parking brake actuator lever goes over a specific amount of travel, the ratchet improvements an adjuster screw and the brake shoes move in the direction of the drum.
Located at the bottom of the drum sits the manual adjustment knob. It can be tweaked making use of the hole on the other side of the wheel. You will have to go beneath the vehicle using a flathead screwdriver. It is really important to be able to adjust each wheel evenly and to move the click wheel properly for the reason that an uneven adjustment may pull the vehicle one side during heavy braking. The most effective method to be able to ensure this tedious task is done carefully is to either lift each and every wheel off the ground and hand spin it 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 perform a road test.
