The iVISOR MK4E2 puts a full range of precise information right in the cab. Designed for use on mobile cranes, the iVISOR MK4E2 is installed and calibrated to the load chart of each crane— including specific load and geometric limits on boom length, angle, and operating radius. This leading edge technology improves the efficiency and productivity of crane operations by giving the operator the information necessary to fully utilize the crane's working capacity, while keeping within the working limits of the crane.
