These benefits lead to high availability and decreased downtime.
A simple rope arrangement allows the AGD Grab Unloader to operate with a low maintenance schedule. The total length of the rope and number of rope pulleys are 60 percent less than those used in conventional unloader designs. Because there is less rope to work, changing the ropes is easier and more efficient than conventional designs. The efficient rope reeving design and advanced AGD control system provide trouble-free operation and ease of maintenance. The result is less operational problems, less maintenance, and better availability.
