The new Boom Raising System for the 440 USt Manitowoc 16000 Wind Attachment is designed to raise longer boom lengths for wind applications without the need of an assist crane.
The Boom Raising System utilizes a large hydraulic cylinder housed in a special 10 ft. boom insert section that attaches to the boom butt. The boom raising cylinder works in conjunction with the boom hoist by exerting an upward force on the boom. This is achieved by extending the cylinder downward onto prepared ground or matting. Once the boom angle is raised to 38 degrees, the boom hoist fully takes over.
