Mule ML150

Summary

The MULE ML150 is a mast-mounted, wire rope lift-assist arm that makes masonry units up to 150 lbs feel weightless for a single mason. It handles CMU, veneer, and cast stone placement across ground base, scaffolding, and mast-climbing work platform configurations; mortar application, cutting, and layout stay with the crew. The ML150 has been shipping since 2020, with 8 confirmed deployments across healthcare, warehouse, cultural, and military projects in the United States.

Unit Placement (Brick/Block/Stone)

How it works on your site

Unit Placement (Brick/Block/Stone)

The operator grips the block with pneumatic grippers and the system continuously adjusts wire rope tension to counterbalance the load weight, making units up to 150 lbs feel weightless in float mode. One mason places blocks that previously required a two-person lift, including oversized 32-inch CMU that covers twice the wall area of a standard 16-inch block. After placement, the arm auto-retracts and performs small autonomous repositioning movements.
