Not only is crane operation with an anti-two blocking system safer, it is required by OSHA on cranes dated 1992 or newer, that have previously had an anti-two block system, or are used to lift personnel. This ‘change of state’ issues a warning and/or stops the upward movement.

If the crane’s hook travels too far upward, it pushes up the weight and releases tension on the switch. XCMG truck crane HIRSCHMANN LMI A2B switch -if you need other parts, please contact us by: E-mail. Sensing and Control An anti-two block system consists of a sliding weight, which hangs on a switch. Through this arrangement, the distance between the hoist drum and the boom tip sheaves increases as the boom is lowered, causing the lower block (hook block) to move closer to the upper block (boom tip sheaves).

One type of two- blocking, often described as “booming down into the block,” occurs on cranes because of the location of the hoist drum, which is typically mounted on the revolving superstructure. Essentially, anti-two block systems prevent events caused by unintentional contact between the hook block (ball) and the boom point, often referred to as two-blocking. Straight, angled, overmolded or freely assembled standard connectors. Without anti-two block protection, operators can pull the hook and load through the crane body, damaging the crane or causing safety risks. Hirschmann offers a broad portfolio of Industrial Connectors - highly reliable even in the most challenging situations. PAT Hirschmann Anti Two Block warning systems are used on cranes to halt or caution the operator of unsafe upward movement of the hook.
