Presenter Tony Bosnich 2015 Planning and Organising Two Plant and Equipment -Cranes- ConstructioConstru cc 2 : 2012 Construction Practice 2 : 2012 Use title slide layout Presenter Tony Bosnich 2015 © Unitec New Zealand >>DEPARTMENT OF CONSTRUCTION

Learning outcomes 1.Analysis crane requirements for large commercial building 2.Consider options and confirm selection. This one of the most important plant Selection made for any project 3.Carry out Crane Demand Analysis to confirm validity of selection and highlight any problem areas. 4.Analysis options and put methods in place mitigate risk. To achieve a new layout – insert a new slide, then in the slide thumbnail left side view, Right Click, choose layout – and pick a content style to use >>DEPARTMENT OF CONSTRUCTION

1.Analysis crane requirements for large commercial building Analysis site constraints Constraints and the way we deal with them are the single biggest factor affecting the overall success of the project Run through check list 1. DEPARTMENT OF CONSTRUCTION

What are the crane constraints of this site 1 2 3 4 5 6 7 8 9 10 >>DEPARTMENT TITLE EDIT IN HEADER & FOOTER

Crane Lifting Specific Constraints Heavy lifts Large number of lifts Big pours Adjoining properties Services - danger of contact Communications Movement on site of material Public protection DEPARTMENT OF CONSTRUCTION

Activity Consider plan provided. 1 Activity Consider plan provided. 1. Identify constraints from list on previous slide. 2. What type of crane would be suitable? 3. Where should we locate it 4. What is configuration of base 5. Is it free standing or climbing 6. How do we erect it 7. How do we take it down upon completion DEPARTMENT OF CONSTRUCTION

Selection of Crane Which of these is suitable DEPARTMENT OF CONSTRUCTION

Where are we going to locate it On our plan determine Location of largest lift? Where are we lifting from? Consider lifting circle ,location is governed by being able to lift from delivery position and place in finished location with out shifting crane. DEPARTMENT OF CONSTRUCTION

Location continued Exterior of building? Inside building? Consider base Tracked Counter weights Cast insitu base or piles (Sacrificial) Study data sheet provided DEPARTMENT OF CONSTRUCTION

Luffing Tower crane

Crane Data Sheets Look at sample . Note Lifting capacity varies with Radius from Centre and Revs or parts of lifting rope In SOME construction cranes the primary use is not to INCREASE lifting capacity but rather to gain control over the lifting operation. The more parts the smoother the lifting operation ,allows for very precise placing movements of loads DEPARTMENT OF CONSTRUCTION
