There are significant differences between 2-wheel and 4-wheel steering in electro-hydraulic transfer carts. Two-wheel steering offers a simpler overall structure and lower cost. It primarily achieves steering through a differential speed ratio between the 2 wheels, resulting in a larger turning radius. However, its wheels are prone to slipping at low speeds or under heavy loads, which limits maneuverability. For example, a traditional 2-wheel differential chassis requires multiple reverse adjustments to turn in a narrow space, making it inefficient.
4-wheel steering transfer carts optimize turning performance by independently controlling the speed or steering angle of each wheel. Using electro-hydraulic steering technology, the hydraulic system precisely adjusts the power output of each wheel to achieve a much smaller turning radius.
For instance, a 4-wheel drive trackless transfer cart can rotate 360° on the spot, resulting in a very small turning radius. This makes it particularly suitable for confined locations such as warehouse aisles and production lines. Furthermore, 4-wheel drive offers greater stability when climbing slopes or driving on slippery roads, providing more balanced power distribution and preventing steering failure caused by single-wheel slippage.
Generally speaking, if the customer's workspace is limited, 4-wheel steering is more advantageous. 2-wheel drive, whereas, is suitable for scenarios with a limited budget and an open site.
