A breach sling system used to quickly and efficiently remove material and items. Using this system may allow law enforcement personnel to quickly remove material and items such as doors and windows from structures, which allows law enforcement to quickly breach and enter a structure. Breaching hooks, used by law enforcement personnel, may be embedded into material and items. Attached to ropes, the breaching hooks may be pulled using a vehicle, which may exert enough force on the material and items to remove them from a structure.

An improved remote sling release for a crane has a main plate member including an access hole for attaching a main crane hoisting line therethrough, a hook portion located at an opposite end from the access hole and adapted to selectively hold securely or release sling members thereon. Two sling ejector plate members connected to one another such that the ejector plate members are pivotally attached to the main plate member, wherein each of the sling ejector plate member has a sling notch therein adapted to receive the sling members of a hoist pallet therein. A sling access handle member attached to at least one of the sling ejector plate members and used to manually rotate the ejector plate members from an open position for receiving the sling members therein and into a closed position, wherein the sling member are locked upon the hook portion of the main plate member. A remotely controlled solenoid mechanism attached to the main plate member and adapted to unlock the locking mechanism, and a first traction spring member adapted to bias the ejector plate members into the open position and force the sling members off of the hook portion. A remote control mechanism adapted to remotely activate the solenoid mechanism, to force the sling members off of the hook portion.

The present invention discloses a super large tonnage detachable hook. The hook comprises: a hook rod, a hook shaft, a hook body, a spherical roller bearing, and a thrust spherical roller bearing. The hook also contains a connection component which connects the hook rod to the hook body. The split-type self-locking sleeve is integrally connected to the hook rod via the hook hoop holder. Meshing of the sleeve with the toothed sleeve of the hook rod is adopted to transmit the load, and the bearing capacity is greatly improved compared with the traditional screw connection. The hook of the present invention can withstand the downward and upward bi-directional load, which solves the problem that the traditional hook is prone to damage once it hits the ground. The hook is forged with 30CrNiMo8, which can lift an extremely large weight of more than 5,000 tons.
