Embodiment Construction

[0044] The following is attached Figure 1-5 The application is described in further detail.

[0045] The embodiment of the present application discloses a horizontally rotatable cross spreader with two lifting points. refer to figure 1 , a horizontally rotatable cross sling with two lifting points, comprising a sling body 1 , a sling 3 and a lifting mechanism 2 . The sling 3 is located at the bottom of the sling body 1. In the present embodiment, the sling body 1 is arranged in a cross shape, and each end of the sling body 1 is provided with one above-mentioned sling 3 to facilitate the lifting of the suspended member. The lifting structure is located on the side of the spreader body 1 away from the lifting rope 3 .

[0046] refer to figure 1 , the hoisting mechanism 2 comprises a balance bar 21 and steel wire ropes 22 arranged at both ends of the balance bar 21, the two ends of the balance bar 21 are hingedly provided with a first connecting rod 44, and the end of the fi...

Abstract

The invention relates to a cross-shaped lifting appliance with two lifting points capable of horizontally rotating and belongs to the technical field of lifting appliances. The cross-shaped lifting appliance comprises a lifting appliance body; a lifting mechanism is arranged on the lifting appliance body; a plurality of lifting ropes are arranged on the surface, far away from the lifting mechanism, of the lifting appliance body; the lifting mechanism comprises a balance rod and steel wire ropes movably arranged at the two ends of the balance rod; and a rotating assembly is arranged between thebalance rod and the lifting appliance body. Due to the arrangement of the steel wire ropes movably arranged at the two ends of the balance rod and the rotating assembly, when the lifting appliance body rotates, the phenomenon that the balance rod drives the steel wire ropes to be distorted is not prone to occurring, namely, self-adaptive rotation can be achieved, so that the steel wire ropes canbe protected, and when a lifted component rotates, the steel wire ropes are not easily damaged; and the lifting appliance body can be kept in a vertical state all the time.

Description

technical field [0001] The present application relates to the technical field of hoisting slings, in particular to a cross sling with two lifting points that can rotate horizontally. Background technique [0002] In the construction industry, component lifting is divided into single-point lifting, two-point lifting and multi-point lifting. [0003] In the construction of large bridges, the lifting components are getting heavier and heavier, and the heavier ones use gantry cranes. In related technologies, two-point cranes are generally used. In general, connect the steel wire rope to the sling, fix the suspended component on the sling, and then pull the steel wire rope to lift the sling, and then the suspended component can be hoisted. [0004] The inventor believes that when lifting, the steel wire rope is twisted due to the rotation of the suspended component, which can easily cause damage to the steel wire rope at the two lifting points, which may lead to safety accidents...
