Embodiment Construction

[0042] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0043] Such as Figures 1 to 9 As shown, according to an embodiment of the present invention, a boom loading method is used for loading a boom. The boom to be hoisted includes a first boom section 11 and a first boom section 11 that needs to be installed in the first boom section 11. The second boom section 20 needs to be hoisted and assembled to the first boom section 11 when the boom is in use, and the second boom section 20 needs to be removed from the first boom section 11 after use. An upper slider 21 is arranged at the tail of the second boom section 20 . Jib loading methods include:

[0044] The first boom section installation adjustment step is to extend the first boom section 11 by the fi...

Abstract

The invention provides a crane arm loading and unloading method and a crane arm. The to-be hoisted crane arm comprises a first arm section and a second arm section installed in the first arm section, and the tail part of the second arm section is provided with an upper sliding block. The crane arm loading and unloading method comprise: a step of installing and adjusting the first arm section, namely, enabling the first arm section to stretch out according to a first stretching quantity and changing the amplitude of the first arm section to be 0 DEG; a step of installing and adjusting the second arm section, namely, hoisting the second arm section through a hoisting assembly, adjusting the hoisting assembly to enable the head part of the second arm section to be lifted upwards by a first angle Pi, adjusting the second arm section to enable the upper sliding block of the second arm section to have a height capable of exactly entering the head part of the first arm section at the height direction, and adjusting the gap between the sidewall of the second arm section and the sidewall of the first arm section; and a step of putting the second arm section into the first arm section, namely hoisting and installing the second arm section into the first arm section, and fixing the second arm section to the first arm section. The crane arm loading and unloading method is capable of rapidly loading the crane arm.

Description

technical field [0001] The invention relates to the field of booms, in particular to a method for loading and unloading a boom and a boom. Background technique [0002] Large-tonnage truck cranes, especially super-large-tonnage truck cranes, generally have different operating conditions for the combination of telescopic boom sections and tower booms, and some telescopic boom sections need to be disassembled and assembled on the job site. When the boom is disassembled, generally two auxiliary cranes are used to cooperate with each other, and the boom section to be installed is hoisted by the sling. There are also some super-large tonnage truck crane manufacturers who use the method of opening holes on the telescopic boom section to be installed and using a special spreader to hoist the telescopic boom section for disassembly. [0003] The invention patent with the application number 201110385731.9 provides a split method of telescopic boom. The splitting method of the teles...
