boom truck
Load Moment Indicator (LMI) and Anti-Two-Block (ATB) systems are standard on the Series 1400.... The ATB shuts down functions that can cause two-blocking when a winch cable attachment contacts a switch below the sheave case, either by winching up or by extending the boom without paying out cable。
One of the innovative features standard on the Series 1400 Cab Model is internal anti-two-block wiring (patent pending), which routes the ATB system wiring through the inside of the boom. This eliminates the potential of damage to the wire caused by contact with tree limbs, structures or other physical hazards during operation.

预防滑轮组碰撞系统
用于预防吊钩滑轮组(hook block)与起重臂滑轮组(boom block)之间的碰撞。所以称为Anti-two-block system。详见美国专利US Patent 4,219,121：
The present invention relates to an apparatus for preventing a block suspended by a boom cable from engaging a second block mounted on the outer end portion of the boom.
A crane is generally operated with a hook, grab, or similar device connected to a block suspended from by a boom cable. A winch is used to pay in or out the cable to raise or lower the hook etc. In addition, the crane may have a telescoping boom, and the boom may be pivotable from a position where it is nearly horizontal to one where it is nearly vertical. Any one of these operations can cause the block to come into engagement with the outer end portion of the boom from which it hangs. Such engagement can cause severe damage to the crane itself.
Prior art devices have attempted to keep the block a safe distance from the outer end portion of the boom. When there is contact between the tool and the end of the boom, it is called "two-blocking" because the block on the tool comes in contact with the block on the outer end portion of the boom. The present invention prevents this and is called an "anti-two-block" system.

Two-block situation is also called overhoist condition (由于起吊过度导致两组滑轮相撞).

为了简化起见，建议不妨将 Anti-Two-Block system (ATB or A2B system) 译为“防相撞系统”，只要内行能知道它的含意即可。
