CNC steel cage welding machine can process the pile cage by 12m-27m automatically. Based on requirement of construction, the latitudinal rebar will be inserted into the sleeves which fixed on the rotating disk, take longitudinal circle wire and welding it on one latitudinal rebar, when the machine driven and the rotating disk rolling, the longitudinal circle wire will be twines around the rebar, when the disk is moving, it is also rotating, then it will be pile cage. It is controlled by programmable logic controller, the power will be offered by servo motor. There are also hydraulic lifting device under the cage for supporting, welding guns can work automatically according to order.
Automatic Cage Welding Machines are designed as unit construction systems which enables our customers to be flexible in considering the individual interests and requirements. A special version of the Automatic Cage Welding Machine producing polygonal reinforcement cages also sells very well. With this machine, reinforcement cages for pillars and supporting beams can be manufactured as well as reinforced concrete elements, foundation piles etc.

1500mm pile cage: two classes, can process 300-400 meters /day,(about 20 tons).
When Welding a 12-metre steel cage, the general loading and unloading time is approximately 15-20 minutes, normal welding time is approximately 18-25 minutes (spacing 120mm), so the comprehensive time is 30-45 minutes, the speed can be greatly improved after skilled.(generally, the weight of a steel cage with diameter of 1.5 meters and length of 12 meters is about 800 kg)
The efficiency of making pile cage is related to the quantity of the longitudinal rebars, the diameter of the cage, the coil spacing and the skill of workers.
Steel cage template
According to actual requirements, the design of pile cage will be different (such as the quantity or diameter of longitudinal rebar), it’s adaptable to different engineering needs by changing the template and the catheter.
