         dra-Slide to change-out a stacked heat
         exchanger  at  a  Carson  refinery  in  its
         home state of California, USA recently.
           HCR accepted a scope of work that
         covered the emergency removal of a
         260,000-lb. stacked heat exchanger and
         its replacement with a new 279,000-lb.
         unit. The principle complications were
         caused  by major  obstructions  onsite,
         a tight schedule,  and project delays
         inherited from other contractors.  The
         HT500, engineered 100-ton capacity
         modular support stands, and Hydra-
         Pac synchronous hydraulic power unit,
         all from Hydra-Slide, were selected for
         the  task  alongside  additional equip-
         ment from HCR’s diverse fleet.
           Hydra-Slide heavy track  skidding
         systems are one of the most cost-effec-
         tive and accurate methods for moving,
         loading or unloading all types of heavy
         loads where a rigid, load carrying track
         is required.  The HT500 has a total
         height of only 8”, saving jacking time
         and suiting the product for use in con-
         fined spaces. It is engineered for push-
         ing 500 tons and pulling 250 tons with
         a standard double track layout.

         one of the major components of the heav-
