NCDOT is installing a precast ${15}^{\text{'}}-0$ by ${11}^{\text{'}}-0$ Double Barrel Box Culvert across US Higinway $221$ as shown on the attached plans. The precast double barrel weighs $9,000lb\frac{s}{?}$ ff and is provided in $6^{\text{'}}$ long sections. The para meters for the crane lifting operation are as follows.

The Red dashed line on the Plan View for the Culvert represent the $"$No Crane" zone where the Crane wheels, Outriggers or Tracks cannot encroach due to the anticipatedload on the open excavation

The Crane will be allowed to operate along the Dashed Red Line for the entire length of the Culvert $($ a travel path for the $C$ rane may be constructed$),$ the refore the maximum lift distance beyond the Dashed Red Line is ${51}^{\text{'}}*0^{**}$ as shown at the Southwest End of the Culvert.

The area "hatched" in Blue is the operating a rea for the Crane and Delivery Trucks.

The lift radius from the delivery truck is not considered since the trucks will be able to pull directly adjacent to the Crane.

The Ball, Hook and Spreader Bar for any of the Cranes is $2000$ lbs$.$

The Slings are attached to the Spreader Bar such that it creates a $60$ degree angle with the Load at the point of connection. There are $(4)$ Four Pick Points on the Culvert Section.

Based on the Project Plans. Crane Lift Parameters a nd Crane Information; Provide the answers to the following questions but inputting your answers into the text bax provided.; Your answers will need to be supported by calculations, figures, sketches, markups etc to receive full credit for the question.

Identify the Best Crane to complete this activity based on the project parameters minimizing the number of Critical Lifts.

Identify the Boom Length& Angle for the Crane to achieve the required lift radius

Deter mine the load on eachsling and the number of Critical Lifts Required.
