Which feature is likely to destabilize a TLB?

The feature that is likely to destabilize a Telescopic Loader (TLB) is having a heavy rear attachment. This is because a heavy load at the rear can shift the machine's center of gravity, potentially causing it to tip over, especially when lifting loads or maneuvering on uneven ground. Stability is critically dependent on the distribution of weight and the machine's design.

Large front tires generally assist in stability by providing a broader base and better traction on various surfaces, helping to prevent tipping. A low center of gravity is advantageous for stability, as it lowers the risk of the machine tipping over during operation or when uneven forces are applied. An extended wheelbase can improve stability as well, as it increases the distance between the front and rear axles, helping to distribute weight more evenly and reduce the likelihood of tipping.

Thus, while large front tires, a low center of gravity, and an extended wheelbase contribute positively to the overall stability of a TLB, a heavy rear attachment poses a risk by potentially creating an imbalance.
