What is the lifting capacity of a 2-ton wire rope come-along when configured for a double line pull?

1. 1 Ton

2. 2 Tons

3. 4 Tons

4. It depends on the load

The correct answer is: 2 Tons

When a wire rope come-along is configured for a double line pull, the capacity effectively doubles. A standard 2-ton capacity indicates that the come-along can lift up to 2 tons when using a single line. However, by employing a double line pull configuration, the mechanical advantage allows the come-along to lift twice as much weight, resulting in a lifting capacity of 4 tons. Choosing an option of 2 tons does not take into account the benefit of the double line pull mechanism, which is specifically designed to multiply the load-carrying capacity by utilizing both sides of the rope. It’s essential to understand that the capacity does indeed increase in this setup, so recognizing that the capacity can be increased through configuration is crucial for safe and effective use of lifting equipment.
