What is the main purpose of the counterweight in a counterweight balance type stacker?

The main purpose of the counterweight in a counterweight balance type stacker is to maintain front and rear stability. Forklift trucks, particularly those using a counterweight design, often experience significant changes in weight distribution as loads are lifted and moved. The counterweight serves to balance out the weight of the load, ensuring that the operator has better control and the machine remains stable during operation.

When a load is raised, the center of gravity shifts. By having a counterweight at the back, it helps counteract the forward tilt that can occur, preventing the stacker from tipping over. This stability is crucial for safe operation, especially in environments where loads may be hefty or when navigating uneven surfaces. Ultimately, the counterweight plays a vital role in allowing the stacker to function effectively while ensuring the safety of the operator and the load.
