Forklift Brakes - A brake drum is where 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 kinds along with certain specific differences. A "break drum" would normally refer to when either pads or shoes press onto the interior exterior of the drum. A "clasp brake" is the term used in order to describe when shoes press against the outside of the drum. Another type of brake, called a "band brake" utilizes a flexible belt or band to wrap around the outside of the drum. If the drum is pinched in between two shoes, it could be referred to as a "pinch brake drum." Like a standard disc brake, these kinds of brakes are rather uncommon.
Prior to the year 1995, old brake drums required consistent modification periodically so as to compensate for shoe and drum wear. Long brake pedal or "Low pedal" travel is the hazardous end result if modifications are not executed sufficiently. The motor vehicle can become dangerous and the brakes can become ineffective when low pedal is mixed with brake fade.
There are various Self Adjusting Brake Systems existing, and they can be categorized within two major kinds, RAI and RAD. RAI systems have in-built equipments that prevent the systems to be able to recover whenever the brake is overheating. The most recognized RAI manufacturers are Bosch, AP, Bendix and Lucas. The most well-known RAD systems include AP, Bendix, Ford recovery systems and Volkswagen, VAG.
The self adjusting brake will usually only engage when 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 utilized on the front wheels of motor vehicles today. By working 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 take place, which raises fuel consumption and accelerates wear. A ratchet tool that becomes engaged as the hand brake is set is one more way the self adjusting brakes could work. This means is just appropriate in applications where rear brake drums are used. When the emergency or parking brake actuator lever goes beyond a specific amount of travel, the ratchet improvements an adjuster screw and the brake shoes move toward the drum.
Situated at the base of the drum sits the manual adjustment knob. It could be tweaked utilizing the hole on the other side of the wheel. You will have to go underneath the vehicle utilizing a flathead screwdriver. It is really important to adjust each wheel evenly and to move the click wheel correctly as an unequal adjustment may pull the vehicle one side during heavy braking. The most effective method so as to ensure this tedious task is completed safely is to either raise 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 exact amount of manual clicks and then perform a road test.
