Industrial robotics and refractory services specialist LEONARD unveiled a new dual-head, vertical-access robotic demolition arm for demanding industrial applications, including metal producing.

The Descender Duo is designed to demolish tough castable refractory, cut and weld anchors, and spray on refractory inside boilers, calciners, and silos. It delivers up to 50% time savings compared to manual methods and can operate at 100°C+ (212 °F+) for fast deployment after burner off.

As the name suggests, the Descender Duo is lowered into vessels and operated via remote control using its on-board live feed camera, giving operators full visibility while completely removing people from confined, hazardous spaces. By reducing the need for personnel to enter vessels, it also helps shorten the critical path of shutdowns.

Relatively light at less than two metric tons, the Descender Duo is pre-assembled for immediate deployment and, in line with Leonard’s wider suite of robotic arm solutions, requires only a compact 1.2-m² opening to access vessels. Once in position, with the support of an external overhead hoist, the non-loadbearing stabilizing legs are extended using electric hydraulics to secure the Descender Duo as it descends through the vessel.

The dual headed solution offers full 360-degree rotation and is ideal for working in vessels of approximately 9 m (29.5 ft) diameter, however that can be extended with strategic porthole placements. The Descender Duo delivers high productivity with up to 50% time savings compared to manual methods. Its ability to operate at temperatures of 100°C+ (212 °F+) also enables work to begin faster – from as little as 24 hours after burner off – while its all-electric power supply provides a reliable, cost-effective, and cleaner energy source.

The Descender Duo provides double the operational capacity with two robotic heads working simultaneously. Operated using two remote controllers, it gives operators the flexibility to perform the same, or different, tasks simultaneously, from cutting anchors on one arm to demolition and spraying refractory on the other.
