SC&RA Job of the Year: The clamp champ
28 May 2025
In removing and replacing a refractory-lined carbon monoxide (CO) line, the Mountain Crane Service team developed an innovative rigging solution that was safe and efficient that won the SC&RA Job of the Year in the Rigging $300,000 to $1 million category.
Mountain Crane Service in the USA applied its experience and know-how to a project that involved the removal and replacement of a 36 to 42-inch refractory-lined carbon monoxide (CO) line within a highly time-sensitive framework.
Mountain Crane Service engineered a solution for replacing a refractory-lined CO line by using SPMT and a stinger clamp system, improving efficiency and safety at elevated heights.
One of the key challenges of the project was the lack of overhead clearance for a crane to pick the line, coupled with obstructions below, that prevented the use of a jack-and-slide operation. To overcome these constraints, the Mountain Crane Service team engineered an innovative solution, using self propelled modular transporter (SPMT) and a stinger clamp system.
This approach ensured enhanced efficiency and provided safer working conditions at elevated heights, addressing the overall challenges of the positioning of the CO line. The stinger clamp system was specifically designed to handle the limitations posed by the lack of clearance and obstructions. An assist crane was brought in for the offloading of the CO line, allowing for a smooth and secure operation.
Remarkable engineering
Mountain Crane’s in-house engineering team, in close collaboration with the field team, designed and executed the rigging plan, eliminating the need for traditional bull rigging methods.
“Remarkably, the Mountain Crane Service team engineered and mobilized the necessary equipment in under one month, a feat that speaks to our expertise and agility,” said Mountain Crane Service’s Tyler Poulsen.
The project was completed successfully, with the client expressing appreciation for the timely, safe and efficient execution of the work, according to Mountain Crane’s Billy Meade.
