Abstract

The invention provides a super-lift counterweight tray and a crane. The super-lift counterweight tray comprises a tray body and a support, the first end of the support is installed on the side of the tray body through a pin shaft, the pin shaft is perpendicular to the supporting face of the tray body, and the second end of the support can rotate around the pin shaft and is contained in the tray body. The tray body and the support are arranged, the first end of the support is installed on the side of the tray body through the pin shaft, the pin shaft is perpendicular to the supporting face of the tray body, the second end of the support can rotate around the pin shaft and is stored in the tray body, and when the support rotates around the pin shaft to the outer side of the tray body, the number of balancing weights for supporting is increased, the needs of super-lift counterweight are met, during transportation, the support rotates around the pin shaft and is stored in the tray body, so that the tray body keeps the original width size, the transportation width requirement is met, the requirements for the super-lift counterweight and the transportation width are both met, the assembling and hoisting efficiency is improved, and the operation safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a superlift counterweight pallet and a crane. Background technique [0002] In order to achieve a larger lifting moment, crawler cranes need heavier superlift counterweights. The more superlift counterweights, the higher the height of the counterweight and the higher the center of gravity will be for the current counterweight pallet. , the worse the stability of the overlift counterweight, if the auxiliary support is added, the pallet will be over-wide, which will affect the transportation. Contents of the invention [0003] The invention provides a super-lifting counterweight pallet and a crane, which are used to solve the defect that the super-lifting counterweight and super-width cannot be taken into account in the prior art, so as to meet the requirements of the super-lifting counterweight and meet the width requirements in the process of pallet transportatio...
