Canada-based Myshak Crane & Rigging has utilised its Hydra-Slide hydraulic skidding equipment to replace a 514-tonne converter at a fertiliser production plant in Alberta.
A 300-ton (272.2-tonne) capacity heavy track HT300 skidding system, in combination with a a 350-ton (348.9-tonne) capacity low-profile LP350 hydraulic skidding system, was used to move the equipment over a 50 m track.
The old converter shell, complete with basket and catalyst, measured 32 m in length and had a diameter of 2.7 m. The unit was jacked up and skidded horizontally in one piece to an open area where it was loaded onto SPMTs.
This made room for the installation of the larger converter shell, which weighed 520.2 tonnes with the basket and measured 3 m in diameter and 35 m in length.
The replacement unit was skidded across the track into position over the foundations and lowered onto the anchor bolts.
Six JLS250 jacking load shoes were hydraulically connected in a three-point suspension to lift and slide the converters on the HT300 track.
