“Wing” is especially designed for the construction and the bridge crane field. The visual language of it had to express “reliability and smoothness” whilst addressing all of the ergonomic issues. The device consists of three types of components: a housing, which grants a high resistance level against accidental blows, a control interface, customized in accordance with the customer’s specific requirement and a base. The housing whose figure is inspired by wings of bird not only protects the joysticks and other buttons, but also integrates with base with an elegant way; the emergency stop button is highlighted at the same time.
