Sectional Masts

Sectional masts work in a different way to telescopic masts in that each tube section is of the same diameter and fits into the next section, a secure guying system is essential for a sectional mast and Clark Masts have a range of specially developed guy winch control systems enabling large masts to be erected in the field by only a small number of people.

Sectional masts have the advantage that they are designed to be fully man portable and can be carried to where they are needed in most off road or armoured vehicles and due to their compact size when packed in individual bags, can also be transported by helicopter, aircraft or boat.

Sectional masts can be erected to any desired height up to the maximum for that model (20m for Type 72, 30m for Type 73 and Series 80 and up to 50m for Series 90). Each section is hoisted via a geared hoist using a guide box supported on field legs, larger headloads can be attached using a crane attachment.

With sufficient guys the field legs can be removed and the mast left in situ for extended periods, this enables several masts to be erected using a single set of field legs.

Type 73 Sectional Mast

Type 73 mast

Type 73 masts have served military forces around the world since the 1970's and set the standard for a modular mast system up to 30 metres in height, lifting headloads of up to 90kgs at 8 metres. The mast sections have an outside diameter of 4 inches and are raised one at a time through the leg mounted mast guide box using the failsafe hoist and cross pin, giving the operator complete peace of mind. Tensioning of guys is controlled by the guy controllers keeping the mast vertical and under tension at all times.
