Heavy Rigging and Hoisting

Kraemer has broad experience erecting complex structures in challenging locations. Our in-house engineering capabilities includes development of detailed erection plans utilizing our wide assortment of conventional and custom-made rigging and lifting devices.

Our teams have safely completed single and multiple crane lifts of pre-stressed elements, steel trusses, arches, thru-plate girders and standard steel girders for a wide range of owners, including state Departments of Transportation, railroads, industrial and private clients.

Kraemer’s specialty jacking equipment is designed to adapt to the most complex lifting operations and capable of lifting a fully-assembled bascule bridge, and structural steel girders or precast segments of up to 1,000,000 lbs, onto an existing or new foundation. These systems have been used to facilitate one day or less change outs of superstructures.

We have developed innovative solutions through our design of a variety of specialized erection equipment units for:

  • Erection Towers
