  How to Choose a Good Forklift Counterweight?  

Many different types of forklifts, fork trucks and lift trucks are used for material handling. While lifting and transporting heavy loads, forklifts need additional weight to secure the counterbalance.

While lifting and transporting heavy loads, forklifts need additional weight to secure the counterbalance.

Counterweights are added to prevent the forklift from tipping over. Even though the counterweights used in the material handling industry are much smaller than those applied in the off-highway industry, they should possess the required weight.

Forklift types that commonly utilize counterweights are the stand-up rider and the sit-down counter-balanced forklifts. Sit-down counter-balanced types commonly place counterweights in between or behind the rear wheels. Stand-up riders are small enough to slip through narrow aisles and have their counterweights in the body compartment. Heavier designs can have removable bulks to ease transportation.

There are two main groups of forklift counterweights:

1. Bulk type: Specifically designed body part at the back end. It is rather a single metal casting or a hollow metal container with mix of concrete and metal.
2. Stack type: Flame-cut cast metal plates stacked onto a base plate or an existing bulk. Stacking or removing plates enables weight change. There can be as many as six plates stacked, each at 2.5 tons.

These both types of forklift counterweights have proven themselves as highly-reliable and safe solutions.

Besides the design every manufacture should rather concentrate on the material selection.

Cast iron counterweights are the best option. Due to forklift's relatively small dimension, counterweights need to have optimal space utilization while still providing the necessary counterbalancing weight. This aspect can only be achieved by using dense materials, such as metal, particularly cast gray iron.

Cheaper materials such as concrete or mix of concrete and metal bits cannot achieve this aspect because they take up larger space for the same weight target. Concrete will need added aggregates or scrap metal bits, shots, or rods to make it denser. But cast metal's density will always be higher than that of aggregated or mixed concrete.
