Detailed Description

In order that those skilled in the art will better understand the present utility model, a technical solution of the embodiments of the present utility model will be clearly and completely described below, and it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, shall fall within the scope of the present utility model.

As shown in fig. 1 to 5.

The utility model provides a movable balance crane base, which comprises a base 1 and is characterized in that: the lower surface of base 1 is connected with the upper surface of bottom plate 12 through support column 11, four arc revolve groove 13 have been seted up to the upper surface of base 1, the intermediate position of bottom plate 12 lower surface is equipped with the base table 14 that the lower extreme has the pulley, the four corners between base 1 and the bottom plate 12 is all through connecting pin 21 movable mounting respectively has support 2, rectangular fluting has been seted up to the one end of support 2 upper surface, grooved inside is fixed with the card post 22 that the upper end runs through revolve groove 13 through spring 23, the other end activity of support 2 inlays and is equipped with extension post 3, the one end threaded connection of extension post 3 has liftable landing leg 4, the intermediate position of extension post 3 lower surface is installed and is removed round 5, the central point flange joint of base 1 upper surface has hoist spliced pole 6.
