Base Engineering is doing a great job on radio remote controls. BASE Engineering is known throughout the world for providing rugged, reliable radio controls for all types of applications including two-way communication between operators and machines. Machine status displayed to the operator handheld adds a level of safety and reduces the risk of catastrophic machine failure – all of this functionality without the need to stand beside the control panel reduces manpower requirements and reaction time.New technologies allow radios to work in areas of extreme electrical interference and adverse conditions.
