Foundation plate for jib crane structural support and load distribution
A structural steel plate component that serves as the primary load-bearing interface between a jib crane's vertical column and the concrete foundation. It distributes operational loads (vertical, horizontal, and moment forces) from the crane structure to the foundation while providing precise alignment and anchorage points for the column base.

Grout fills the gap between the foundation plate and concrete foundation, ensuring full bearing contact and preventing stress concentrations. It provides uniform load transfer and compensates for minor surface irregularities.
Anchor bolts are sized based on maximum uplift and shear forces, with typical diameters of 25-36 mm. They must extend sufficiently into the concrete foundation (minimum 12x bolt diameter) and include proper embedment and edge distance per structural calculations.
Foundation plates are generally not reusable due to potential deformation from previous loading and difficulty in removing embedded anchor bolts. New plates are recommended for crane relocations to ensure structural integrity.
