An addition to the St. David’s Medical Facility in Austin, Texas, required steel beams be placed, but the on-site tower crane couldn’t reach the farthest corner of the structure.
It was, however, able to hoist a Maeda MC 285 mini-crane to the roof and stage the steel beams. Erectors found the mini-crane was much faster assembling the steel because of its close proximity and precision placement, according to Maeda. The mini-crane operator was able to closely monitor the workers on the beams and communicate directly with them, which also improved the safety of the steel erection.
The mini-crane was a less expensive alternative than a large mobile crane rental, according to Maeda. The crew was able to bolt-up the steel columns and beams in a day on the rooftop corner. The track-mounted MC 285, which was rented from Inman Texas in Houston, was able to maneuver on the roof with its compact 30-inch width.
