Operations training
Crane and Hoist / V1 2023-07-03
After having successfully completed this lesson the participants can use relevant documents to:
28) Explain how to perform calibration checks for a crane load cell and boom-angle and slewing-angle encoder (Knowledge, intermediate level) 29) Perform a test lift with a load of between 150 and 250 kg and compare between the actual load and the crane load cell or compare the actual position of the boom and the boom angle or radius indicator (Skills, intermediate level) 30) Recognise any fault warnings, error codes, messages, and alarms detected during test lifts (Knowledge, basic level)
31) Explain the relevant safety systems on cranes (knowledge, intermediate level), for example:
a.
Overload Protection System (OPS)
b.
Automatic Overload Protection System (AOPS)
c.
Manual Overload Protection System (MOPS)
d.
Hoist Overload Protection System (HOPS)
e.
Lateral Boom Protection Systems (LBPS)
f.
Emergency Stop Limiter Switches
g.
Rated capacity indicator (RCI)
h.
Rated capacity limiter (RCL)
Safety systems on the equipment at hand should be presented in this lesson. Alternative safety systems and equipment must be addressed by show-and-tell components, visuals and relevant documentation
Note
The instructor shall:
Present safety systems and indicators and their functionalities on cranes and hoists
Demonstrate how to perform calibration checks for a crane load cell and boom-angle and slewing-angle encoder Facilitate an exercise where the participants discuss and choose relevant safety systems for crane related functions, including load cells and angle encoders
Facilitate exercises in which the participants practise
Provide feedback on the participants’ choices and arguments
