Miller DuraHoist confined space range

Additions to the Miller DuraHoist confined space range includes additional height options and flexibility to suit a variety of applications.

The two-piece mast extension system extends the overall system height to 3.7 m, eliminating the need for a custom-length mast.

Comprising the DH-22, a lower mast extension and either the DH-21 adjustable offset upper mast (12–29″ offset) or the DH-23 adjustable offset upper mast (30–48″ offset), the system provides a wider range of solutions to height-restrictive applications than the DH-3 one-piece adjustable mast alone.

In high-strength corrosion-resistant aluminium, it features a tool-less design for easy dismantling. The system can also be used in conjunction with Miller-approved winches and self-retracting lifeline devices.

Other additions to the range are the two 3-piece portable base options that fit most standard entries - standard DH-4 with 29″ offset and DH-24 with 48″ offset.

The devices feature adjustable screws and built-in indicators for easy set-up on uneven surfaces. Easy to transport and store, the bases do not require tools for dismantling.

Another addition to the range is the vehicle hitch mount sleeve that can be used as a portable anchor point for confined space, rescue and fall arrest systems by being installed into a 2″ receiver on an attendant vehicle.
