Embodiment Construction

[0015] Such as figure 1 , 2 Among them, a rotary spreader suitable for double-machine cranes, including a balance beam 4, at least two lifting points 5 are arranged under the balance beam 4, and the feature is that a distribution beam is also arranged above the two ends of the balance beam 4 1. There is a distribution beam vertical hole 102 in the middle of the distribution beam 1. The vertical shaft 12 passes through the distribution beam vertical hole 102. One end of the vertical shaft 12 is provided with the first spreader 2, and the other end of the vertical shaft 12 passes through the second spreader 3. Connect with the balance beam 4;

[0016] The two ends of the distribution beam 1 are respectively provided with a distribution beam first suspension point 101 and a distribution beam second suspension point 103 . The weight of the hoisting member 7 below the balance beam 4 is reasonably distributed to the first traveling trolley 81 , the second traveling trolley 82 and ...

Abstract

The invention provides a rotary lifting appliance suitable for double-crane lifting. The rotary lifting appliance comprises a balance beam. At least two lifting points are formed below the balance beam. The rotary lifting appliance is characterized in that distribution beams are further arranged above the two ends of the balance beam, the middles of the distribution beams are provided with vertical distribution beam through holes, and vertical shafts penetrate through the vertical distribution beam through holes; one end of each vertical shaft is provided with a first lifting appliance body, and the other end of each vertical shaft is connected with the balance beam through a second lifting appliance body; the two ends of each distribution beam are provided with a first distribution beam lifting point and a second distribution beam lifting point. According to the rotary lifting appliance, the distribution beams are arranged and connected through the vertical shafts, so that the lifting weight is reasonably distributed to first walking trolleys, second walking trolleys and third walking trolleys of two portal cranes through the distribution beams; and besides, the vertical shafts and the distribution beams are in clearance fit, the distribution beams can rotate freely, and the lifting requirements of the positions of the walking trolleys and hooks of various portal cranes are met.

Description

technical field [0001] The invention relates to the field of auxiliary slings for large-scale construction hoisting, in particular to a rotary sling suitable for double-machine cranes. Background technique [0002] The volume and weight of special equipment required by the existing manufacturing and production industries are getting larger and larger, and the requirements for lifting capacity are becoming more and more stringent. Enterprises must expand production capacity and improve hoisting capacity in order to continue to develop, but the cost of investment capital is high, which is unbearable compared with small and medium-sized enterprises. General manufacturing enterprises have their own gantry and bridge cranes. When the lifting weight is too large, they can consider using double-machine platform cranes to improve the lifting capacity. Therefore, it is necessary to develop a spreader suitable for double-machine coordinated lifting. Contents of the invention [000...
