7. Execute a lifting operation
This chapter describes how to perform a lifting operation.
7.1. Risks and Warnings
Good operation of the System is essential for safety. Therefore, address the following
subjects:
Attention
x
It is of the utmost importance to read this manual carefully before setting
up the machine. Failure to prepare correctly for a lifting operation may result
in total loss of machine stability during use.
x
Adhere to the checklists during all work activities: during preparation for
the lifting operation, system construction, and for lifting the load.
x
A unit is only part of the central emergency stop system if the control
selector switch is in the remote position .
x
Ensure that the load avoids contact with a leg, header beam, other
components of the system or any obstructions while lifting, side shifting, or
traveling.
x
The operator should have an unobstructed view of the system and load
during operation of the system. If this is not possible, a signalperson shall
be used with an effective means of communication to provide directions to
the operator.
x
Communication among personnel involved in the operation shall be
maintained continuously during all movement of the load. If at any time
communication is disrupted, the operator shall stop all movements until
communication is restored.
x
Signals to the operator should be in accordance with the standards
prescribed in section 1.8.6 “ Hand signals ”. If special signals are required,
they shall be agreed upon by the operator and support personnel prior to
the lifting operation. Signals shall be discernible or audible at all times. No
action shall be taken unless signs are clearly understood.
x
Load handling personnel shall obey any stop signal.
Hazard
x
Improper use of the machine or failure to take the changes indicated in this
manual into consideration may result in accidents causing damage not only
to the machine itself, but also to objects and goods in its vicinity or mounted
to the machine, as well as injuries to people in the immediate area, and
possibly even death.
x
Adhere to the checklists during all work activities: during preparation for
the lifting operation, system construction, and for lifting the load.
Failure to adhere to the checklists may result in serious injury to the user,
possibly even death.
x
Do not extend booms when a person is close to.
x
Local control is only permitted if there is no header beam attached to the
unit. A unit is only part of the central emergency stop system if the control
selector switch is in the
remote position .
Caution
x
When lifting, always assume a worst-case scenario . The wind can be
unpredictable, quickly changing speed and direction. Do not take any
chances: if the wind is strong, that means it's a 'no go'!
x
Never extend or lower booms to which something is attached since the
extension cylinders are not designed to bear additional weight.
