Introduction

These 3 questions are for you to use to help get ready for the load chart part of the CraneSafe Certification assessment for Friction Lattice Crane.

The questions on your assessment will be different from these but will be presented in the same format as these questions.

With the questions are the answers with the relevant load charts. The answers explain how we arrived at the correct answer and you can use this to help work through any questions you may have gotten incorrect. We have not included all of the charts for this crane - but everything you need to answer the questions is included. You do not need the crane manual or full load chart package to answer the questions.
