COURSE OBJECTIVES

On completion of the training course the learners should be capable of:

  • Identifying and selecting the correct lifting equipment and lifting accessories. Be competent in slinging methodology and have the skills to plan a safe lift
  • Inspecting and identifying equipment and pre-use checks
  • Selecting and using synthetic slings
  • Calculations involved in Moving Loads including tension on sling legs, weight, centre of gravity etc.
  • The safety precautions when lifting heavy objects or off centre lifts
  • Planning and moving loads including transfer of loads using various equipment
  • How winches are used, their safe operation and gaining a mechanical advantage with snatch and sheave blocks
  • Be able to complete a working Lift Plan including selection of equipment and positioning of equipment
  • Be able to signal a mobile crane to BS7121 standards

COURSE SYLLABUS

NB: This course includes a recap of the theory and practice of all the subjects dealt with in the Basic Rigging Part 1 Course. There is , however, much more involvement of the learners who will be required to carry out the requisite engineering calculations and to plan, select the appropriate equipment, and carry out all the practical work as team exercises.
