Operations training
Crane and Hoist / V1 2023-07-03
Inspection and maintenance of mechanical components on the work sites may require additional training or support as per the relevant manuals, legislation, and guidelines
Note
HYDRAULIC SYSTEMS
20 min.
The aim of this lesson is to enable the participants to inspect and maintain hydraulic components on cranes and hoists according to manufacturers’ manuals and relevant documents
After having successfully completed this lesson the participants can:
34) Describe the functionality of hydraulic components on cranes and hoists (Knowledge, basic level)
35) Perform visual inspections of the structural integrity of hydraulic components on cranes and hoists, e.g. damage, leaks, deformation on hydraulic hoses and pipes (Skills, intermediate level)
The instructor shall:
Present hydraulic systems, diagrams and components on cranes and hoists
Explain and demonstrate hydraulic systems’ configuration on cranes and hoists, how hydraulic components and systems are functioning, and how hydraulic protective systems operate Explain and demonstrate how to operate the hydraulic system on cranes and hoists after activation of an emergency system (deactivation of hydraulic system, e.g. dump valve)
Demonstrate how to inspect and maintain hydraulic systems and protective systems on cranes and hoists
Facilitate an exercise in which the participants practise how to inspect and maintain hydraulic systems and protective systems on cranes and hoists Facilitate that participants share experiences on hydraulic systems and examine the components demonstrated by the instructor
The participants shall:
Share experiences with crane and hoist hydraulic components and systems and examine the components demonstrated by the instructor Take part in the exercises about the practice of how to inspect and maintain hydraulic systems and protective systems on cranes and hoists
