We have not included all of the charts for this crane - but everything you need to answer the questions is included in the load and jib charts you have here. You do not need the crane manual or full load chart package to answer the the load charts are rigging tables - use these to help answer the rigging questions included in the practice questions.

2 These same rigging charts will be used in your assessment so it is a good idea to become familiar with to the back of this practice exercise is an answer sheet. The answer sheet explains how we arrived at the correct answer and you can use this to help work through any questions you may have gotten crane industry in BC has stated that operators must get a minimum of five out of seven questions right on the load chart and rigging part of the assessment to be InformationOperator Name:Employer:Make & Model of CraneSignature:Assessor InformationAssessor Name:Date of Assessment:Place of Assessment:This section to be completed by OperatorThis section to be completed by AssessorMonth Day YearReference copy OnlyLoad Chart & Rigging PRACTICE Self Erect Tower Crane Potain IGO 50 Tower Crane (1) CraneSafe Certification + Fulford Harbour Group 3 Load Chart & Rigging QuestionsDetermine the increase in capacity when the SM1 Hook Block is installed at full Jib L40 / 131 3 @ 0 degrees Answer.
