ENGINEERING - The story of saving lives in the building industry
The vast majority of small batch concrete used for building is delivered to sites by mobile concrete mixers. When something goes wrong, the operator invariably has to climb inside to sort things out. But it’s a very confined space and pretty dangerous. There have been injuries and even deaths in such situations, not just the person in the confined space but also those who try to rescue them without proper training and equipment.
This company used their advanced laser cutting capability to design and produce a recessed entry hatch and hinge. The sizing and spacing of the hatch was crucial to ensure it missed the concrete mixing paddles on the inside of the drum and that it cleared the external drum support frame. Their innovative system allows a clear opening of sufficient size for rescue operations.
