Barnhart was hired to provide support for a surge tank riser during an outage at a hydroelectric plant in West Virginia. The site was at the end of a narrow and winding access road up a mountain with little room for assembly and trucks.
The team engineered a new tower system using Canton Lift Towers.
The pieces of the tower were lifted and set using a 250-ton all-terrain crane, which was set upon a small crane pad.
Two towers were constructed. Nodes were fabricated at the top of the towers to support two 72-foot beams and four adjustable rigging link setups.
Rigging was connected at the top of the riser, and pull-up jacks were held tight to reinforce the riser while repairs were made to the deteriorating riser sections below. Barnhart provided crane support for the duration of the outage.
