The bottom-slewing GA 136 36tm-class self-erector has inverter control and three speeds on all movements. It has a hexagonal tower to accommodate the two-cylinder mounting system, attachments for moving the crane on the ground, and electrical control panels, motors and equipment, the company says. Transport height is 3.1m and transport length is 13.5m. Maximum height is 20.7m, jib length is 36m, and maximum load is 4t.

This last characteristic makes the series perfect for congested building sites, it adds. The GHS Topless can be positioned on the ground in six configuration. The tower is constructed of tubular profiles of 2m, 6m and 12m lengths, permitting the construction of a maximum height at 48m. The jib and counterjib have been designed so that they can be assembled on the ground to reduce the number of aerial operations and increase safety during assembly. The 90tm-class GHS 160 has a 60m jib, and can lift 1.5t at jib-end. It lifts a maximum load of 6t.

Recently in the Topless family FB has introduced the GHS 513, with a 55m jib, with up to 1.2t at jib end, and a maximum loading of 5t, a lifting height of 48m and all the equipment available on its bigger sibling the GHS 160.
