Most of the braking devices of counterweight balance stackers use drum brakes. Where are they usually located?

Drum brakes in counterweight balance stackers are typically located on the first two wheels, which are commonly the drive wheels. This placement allows for effective braking performance, as these wheels are responsible for not only propelling the stacker but also for managing its stability and maneuverability.

Having the brakes on the first two wheels ensures that the majority of the braking force is applied where it can be most effective, assisting in controlled stopping and enhanced traction during operation. The design also contributes to the overall efficiency and safety of the equipment, making it an industry standard for these types of forklifts. The other options, such as brakes being on the rear, on all four wheels, or just on the front wheels, either do not optimize the braking performance necessary for such equipment or do not follow the common engineering practices observed in the design of counterweight balance stackers.
