Additional Patents

Patent No AU2017900680
Title Sewer Access Chamber Protection System
Type Standard
Status Filed
Filing Date 28/02/2017

This invention relates to a system for protecting the cover of a chamber, such as a sewer access chamber or a manhole, from fluid contact. It is also designed to prevent odours from escaping. This system is designed to be implemented into access chambers or manholes which already have a plastic lining.

Consisting of a frame and lid system, the frame is welded onto the existing frame of the access chamber or manhole. A lid is then secured onto the frame, underneath the existing gatic lid. The original lid is then secured above the entire system, ensuring all fluids and odours have no means of escape.

Patent No AU2011101397
Title A rotary welding system
Type Innovation
Status Granted
Filing Date 21/10/2011

 

This invention is for a rotary welding system to weld on the inside surface of a pipe.

This system was designed to address issues of fatigue management, while improving worker safety and productivity. The extruder welders required to perform this work weigh 8-10kgs, and require a large amount of energy and strength to continuously weld vertical joints around the circumference of large diameter pipes. The rotary welding system supports the entire weight of the welder, allowing the operator to concentrate solely on speed and direction during operation.
