Description

Technical Field

[0001] The utility model relates to the technical field of crane support arms, in particular to a heavy cabinet front crane support arm for logistics. Background Art

[0002] Crane is a common name for hoist, a type of lifting machinery that performs cyclic, intermittent motion. A simple operating cycle involves a lifting mechanism lifting an object from a retrieval location, moving horizontally to a designated location, and then reversing to return the mechanism to its original position for the next cycle. Cranes generally include fixed slewing cranes, tower cranes, truck cranes, tire cranes, crawler cranes, and more.

[0003] When the current crane arm is in use, the crane's handling mainly depends on its arm structure, which often includes multiple telescopic joints to achieve the purpose of suspending and transporting materials. Therefore, the arm structure is often very slender and only relies on a single hydraulic cylinder at the bottom for tilt support when in use. It is not stable and has the risk of rollover, especially in some extreme weather conditions. Therefore, a heavy cabinet front crane arm for logistics is needed. Utility Model Content
