A sling-traverse device for lifting system for elevation of the massive objects
(constructions) provides a possibility to lift the solid over size and over weight
objects. An improved sling-traverse device for massive construction lifting system
includes an arched form traverse, a traverse connector, comprising a traverse flange,
a lower portion of which is by a traverse hinge coupled with the traverse, and
a sling flange, an upper portion of which is intended for coupling with the lifting
system, and the opposite sides of the traverse flange and the sling flange are
rigidly connected to each other. The traverse includes two pairs of levers on each
of side of the arch, and each two appropriate levers are coupled to each other
by the stiffener and resting girder in their frontal lower part. Also the improved
sling-traverse device includes a pushing spiral springs with a directional fingers
respectively coupled with the appropriate brackets connected to the appropriate
shackles and levers.
