1. Planning and Organising Two Plant and Equipment - Cranes- ConstructioConstru cc 2 : 2012 Construction Practice 2 : 2012 Presenter Tony Bosnich Glenn Edmonds 2014 © Unitec New Zealand >>DEPARTMENT OF CONSTRUCTION

2. >>FACULTY OF TECHNOLOGY AND BUILT ENVIRONMENT 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. >>DEPARTMENT OF CONSTRUCTION Learning outcomes

3. >>FACULTY OF TECHNOLOGY AND BUILT ENVIRONMENT 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. 3 DEPARTMENT OF CONSTRUCTION

4. >>FACULTY OF TECHNOLOGY AND BUILT ENVIRONMENT 1 2 3 4 5 6 7 8 9 10 What are the crane constraints of this site >>DEPARTMENT TITLE EDIT IN HEADER & FOOTER

6. >>FACULTY OF TECHNOLOGY AND BUILT ENVIRONMENT 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 6 DEPARTMENT OF CONSTRUCTION

7. >>FACULTY OF TECHNOLOGY AND BUILT ENVIRONMENT Which of these is suitable Selection of Crane 7 DEPARTMENT OF CONSTRUCTION

8. >>FACULTY OF TECHNOLOGY AND BUILT ENVIRONMENT 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. Where are we going to locate it 8 DEPARTMENT OF CONSTRUCTION

9. >>FACULTY OF TECHNOLOGY AND BUILT ENVIRONMENT Exterior of building? Inside building? Consider base Tracked Counter weights Cast insitu base or piles (Sacrificial) Study data sheet provided Location continued 9 DEPARTMENT OF CONSTRUCTION

11. Luffing Tower crane

12. >>FACULTY OF TECHNOLOGY AND BUILT ENVIRONMENT Look at sample. Note Lifting capacity varies with Radius from Centre and Revs or parts of lifting rope Crane Data Sheets 12 DEPARTMENT OF CONSTRUCTION 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

13. >>FACULTY OF TECHNOLOGY AND BUILT ENVIRONMENT >>DEPARTMENT OF CONSTRUCTION Analysis data from Crane specification sheet

14. >>FACULTY OF TECHNOLOGY AND BUILT ENVIRONMENT Is this crane suitable for the job? Consider all lifting requirements for typical floor.
