Forklift Brakes
Forklift Brakes - A brake drum is in which the friction is supplied by the brake shoes or brake pads. The pads or shoes press up against the rotating brake drum. There are a few other brake drums types together with certain specific differences. A "break drum" will generally refer to if either pads or shoes press onto the interior surface of the drum. A "clasp brake" is the term used to be able to describe when shoes press against the exterior of the drum. Another kind of brake, called a "band brake" makes use of a flexible belt or band to wrap around the outside of the drum. Where the drum is pinched in between two shoes, it can be called a "pinch brake drum." Similar to a typical disc brake, these kinds of brakes are somewhat rare.
Early brake drums, before 1955, required to be constantly modified in order to compensate for wear of the drum and shoe. "Low pedal" can cause the required adjustments are not carried out sufficiently. The motor vehicle could become hazardous and the brakes can become ineffective when low pedal is combined together with brake fade.
There are some various Self-Adjusting systems utilized for braking offered today. They could be classed into two individual categories, the RAI and RAD. RAI systems are built in systems that help the apparatus recover from overheating. The most well known RAI makers are Bosch, AP, Bendix and Lucas. The most famous RAD systems consist of Volkswagen, VAG, AP, Bendix and Ford recovery systems.
The self adjusting brake would normally only engage when the forklift is reversing into a stop. This method of stopping is suitable for use where all wheels use brake drums. Disc brakes are used on the front wheels of motor vehicles nowadays. By operating only in reverse it is less probable that the brakes will be adjusted while hot and the brake drums are expanded. If adjusted while hot, "dragging brakes" could take place, which raises fuel consumption and accelerates wear. A ratchet tool which becomes engaged as the hand brake is set is another way the self repositioning brakes could function. This means is just appropriate in applications where rear brake drums are used. If the emergency or parking brake actuator lever exceeds a particular amount of travel, the ratchet improvements an adjuster screw and the brake shoes move toward the drum.
There is a manual adjustment knob located at the bottom of the drum. It is usually adjusted through a hole on the other side of the wheel and this requires getting beneath the forklift along with a flathead screwdriver. It is of utmost importance to move the click wheel properly and modify each wheel equally. If unequal adjustment happens, the vehicle can pull to one side during heavy braking. The most efficient method to be able to make certain this tedious task is done safely is to either lift 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 each one the same amount of clicks manually and then perform a road test.
