Load Chart & Rigging PRACTICE Mobile Hydraulic Link-Belt HTC 8660 Telescopic Crane (1)

www.fulford.ca CraneSafe Certification + Fulford Harbour Group 2

Introduction

These 10 questions are for you to use to help get ready for the load chart and rigging part of the CraneSafe Certification assessment for Mobile Hydraulic Crane.

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

Following the questions are load charts and jib rating charts. 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 questions.

Following the load charts are rigging tables - use these to help answer the rigging questions included in the practice questions. These same rigging charts will be used in your assessment so it is a good idea to become familiar with them.

Attached 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 wrong.

The crane industry in BC has stated that operators must get a minimum of seven out of ten questions right on the load chart and rigging part of the assessment to be competent.
