Existing Technology
PROBLEM
(1) Many Parts loss
(2) Long crane working hours
Carrying upper rebar during existing
couplers are tighten by tools
(3) Waste of labor cost
More than 2 workers are required
(4) Dangerous Working Environment
Long operation time with another tools
& high risk of accident
(5) Available Shape

ROC
SOLUTION
(1) Few Parts loss
(2) Short crane working hours
Shorten working hours of crane carrying
reinforced rods
(3) Save labor cost
Only 1 workers are required
(4) Safe Working Environment
Improve worker’s safety from falling down of parts.
(5) Available rebar shape
All kinds of rebar (Horizontal & Diagonal)
Steel bar & Bolt screw
