Description

Technical Field

[0001] This utility model relates to the field of crane hoisting, specifically to a crane mechanism that allows for interchangeable operation of a tower-type jib and a fixed jib. Background Technology

[0002] Tracked cranes typically operate in three standard conditions: main boom, fixed jib, and tower jib. The fixed jib condition consists of the main boom, fixed jib, jib support, fixed jib anti-tilt mechanism, fixed jib front tie plate, and fixed jib rear tie plate. The tower jib condition consists of the main boom, tower jib, tower jib rear support, tower jib front support, tower jib front tie plate, tower jib rear tie plate, tower jib front anti-tilt mechanism, and tower jib rear anti-tilt mechanism. Usually, the fixed jib and tower jib are two independent boom systems with no commonality. That is, the fixed jib, jib support, fixed jib anti-tilt mechanism, fixed jib front tie plate, and fixed jib rear tie plate are not interchangeable with the tower jib, tower jib rear support, tower jib front support, tower jib front tie plate, tower jib rear tie plate, tower jib front anti-tilt mechanism, and tower jib rear anti-tilt mechanism. The variety of boom sections, tie plates, and anti-tilt mechanisms makes production organization, storage, and daily management difficult, and increases the operating costs for the client. Utility Model Content

[0003] To address the aforementioned technical deficiencies, the purpose of this utility model is to provide a crane mechanism that allows for interchangeable operation of a tower-type jib and a fixed jib. The fixed jib can be formed by changing and combining tower-type jibs.
