Brake squeal or other noises are much questioned by forklift operators, but these sounds do not constantly signify a trouble with the forklift. Different brake designs and materials complicate our ability to troubleshoot, plus cars are our chief point of reference for brakes. Cars have ( 4 ) bicycle brakes and most forklifts have only ( 2 ) roulette wheel brakes. The power brakes, semi-metallic / ceramic pads and anti-lock systems for cars are besides different and can not be compared to forklifts .
Several braking or speed reduction systems are available on forklifts. Below is an overview:
Drum & Shoe Brakes
This brake includes a cram, shoes and hydraulic steering wheel cylinders. It ’ mho common to the rise brakes of most cars and is the most common brake design used on forklifts.

Disc brakes consist of a rotor, a mechanical, hydraulic or air-operated caliper and clash pads. This type of brake is common on the battlefront axle of most automobiles and used in some forklift applications .
Discs similar to transmission clutches are located inside the drive axle and are lubricated and cooled by the transmittance fluid or axle anoint. Hydraulic blackmail is used to squeeze the friction disk packs and slow the drive axles. The advantage of wet brakes is they rarely require refilling.

Air brakes use compressed publicize pressing on an actuator to apply the mechanical force to the brake horseshoe or pad. Air brakes are used in larger heavy vehicles. These systems require an engine-driven air travel compressor and air blackmail is tightly governed .
Hydrostatic Drive Brakes
The forklift is driven by hydraulic oil from a pump driven by the engine to hydraulic motors at the wheels. When drive is not requested, vegetable oil stops flowing and a natural brake impression is the resultant role as petroleum can ’ t exhaust out of the bicycle motors. This type of brake is used in some forklifts, many forward pass lifts and chiefly for construction equipment.

Dynamic, Plugging or Regenerative Braking
Drive systems on electric forklifts and other electric drive systems have the capability of using magnetism in the drive motors to magnetically slow the drive centrifugal armature by changing direction ( i.e. advancing to reverse ) .
No one is safe on or around a forklift with faulty brakes. All braking systems require adjustments, making maintenance and compensate critical. Contact ProLift to schedule a technician at your site !
