PURPOSE: A device for preventing a cargo-handling machine having a clamp rail from being pushed is provided to stably prevent a cargo-handling machine from being pushed, to prevent damage of the equipment and accidents, to improve efficiency of cargo work. CONSTITUTION: A device for preventing a cargo-handling machine having a clamp rail from being pushed is composed of a clamp rail unit, a supporting unit, and a link unit. The device for preventing a cargo-handling machine from being pushed is installed to the lower part of a supporting boom and operates plural links and a jaw connected to the link and fixes a cargo-handling machine to a rail(111) or separates. The clamp rail unit pressurizes the rail from both sides. The supporting unit makes the fixing and separating motion performed while supporting the clamp rail. The link unit transmits driving force caused by a cylinder and spring to the supporting unit. The clamp rail unit includes a clamp rail(212), a jaw(218), and a guide bar(215) and the supporting unit includes a support(210) and a stopper(223). Dispersing pressure given to the jaw to fix the cargo-handling machine when drifting is occurred prevents drifting of the cargo-handling machine more stably.
