Hauling shaft and ropes

Hauling shaft  

A hauling shaft is used to properly control the pulk on uneven and steep ground and the Snowsled shaft is specially designed to even out the stresses imposed on the system. However, it may be dangerous to use in areas such as pack-ice, when heavy pulk loads may be difficult to control, and where ropes are a safer option.

  • the innovative Snowsled hauling shaft system is unrestricted in the vertical plane. 
  • maintains maximum stability horizontally.
  • cross-bar system helps maintain pulk behind hauler.
  • allows significant twist.
  • can be packed easily within the pulk for shipping and storage.
  • plastic components are either UHMW polyethylene or acetal, rated to below -40C.
  • the black acetal cross-bar brackets allow the cross- and side-tubes to twist with respect to one another.
  • the main shaft can be detached and replaced with ropes, just threaded through the holes in the pulk arms.

Snowsled hauling shaft connections only fit Snowsled harnesses. However, we may be able to accommodate other manufacturer’s harness designs – please ask.

Ropes

Rope hauling is useful when travel is mainly over fairly flat areas. Our hauling ropes are 8 mm red braided polypropylene (which floats), and include a heavy duty 10 mm shock absorber loop. The whole assembly allows about 2.5 m between hauler and pulk.

Ropes are attached to the hauling harness waistbelt loops by carabiners (optional purchase). It may also be convenient to put a carabiner into the system between the shock cord loop and where the hauler’s end is attached, making it easy to quickly unhitch from the system.

The carabiners (DMM pro wire – gate closed 24kN) may be used in suitable climbing or rescue situations when security has to be assured – they are not screwgates however.Trail rope attachment DSC03057

Attachment to the pulk depends on which size of shell is being used, as follows,

Trail shells always have rope hauling holes (10 mm) drilled as standard, in the top of the flange
towards the front.

For Expedition pulks, the best position for hauling is lower down. If a hauling shaft or ropes are ordered, holes will be predrilled for these. Shaft attachments and rope loops both use the same holes.

Where provision is only required for rope hauling, hauling loops need to be ordered.  They are supplied with nuts, bolts and washers to attach through these holes.  Rope attachement using shaft pulk arms.P1010548

If changing from shafts to ropes during an expedition, the pulk arms are left attached and ropes threaded through the holes provided, as shown.
