A 300 ton capacity ringer crane with 260 foot boom was chosen to erect two second generation container cranes on two separate docks in Vancouver. Precise crane locations were required as the three main lifts (house, back girders and boom) were maximum picks with minimum clearance, each from an unique location. Exact centre of gravity calculations were carried out and all lifting lugs and rigging were designed by Somerset. The 100 ton boom lift was set at precisely 70 degrees with the crane positioned to clear the front portal legs and the boom itself, all within capacity. To complicate this lift, the ringer was located on a hollow celled dock. Imposed loads from raising boom, swinging and positioning were all checked out. Our 3D CAD layout of this lift is shown here as well.
