Bronto Skylift S-158 MDT (medium-duty telescopic) aerial-work platform has a 158-foot working height and 1,000-pound unrestricted platform capacity. Road-legal in most states, it's mounted on a commercial chassis. Bronto's +2 system is a microprocessor-enhanced control system that continuously compares data from the linear tracking and encoding devices to ensure safe operation. Boom sections are lighter weight because the system eliminates operators' ability to overstress the booms or overload the platform. Gross weight is 54,000 pounds. Estimated list price: $450,000.
