HOISTING ROPE CONNECTION DEVICE AND HOISTING EQUIPMENT

WIPO Patent Application WO/2016/045612

A1

A hoisting rope connection device and hoisting equipment; the hoisting rope connection device comprises a connecting bracket (10) provided with at least two inverted-V-shaped connectors, a connecting cylinder (15) and a connecting shaft (14); first connecting holes (11) are provided at the corners of the at least two inverted-V-shaped connectors for connecting to the hoisting rope (3); the connecting shaft (14) passes through the first connecting holes (11) and the connecting cylinder (15) and is fixedly connected to the at least two inverted-V-shaped connectors; the two ends on the bottom of the at least two inverted-V-shaped connectors are respectively detachably connected to two sides on an upper portion of a distal end (2) of a main arm to form a firm and reliable triangular structure; and a height difference between the top and bottom of the connectors allows the connection points of the hoisting rope (3) connected to the first connecting holes (11) on the top to be located at a higher position, thus effectively reducing the deformation of a hoisting main arm. In addition, in a non-hoisting working condition, the hoisting rope connection device can be detached to ensure that the height of the entire hoisting equipment does not exceed a height limit during transportation.
