3.5.4 Notes on the SLI shutdown
Operation with the swing-away lattice is monitored by the SLI.
When operating with the swing-away lattice, SLI shutdowns can occur
for the same reasons as when operating with the main boom;
à Operating
instructions GMK 4100/4100-L/5095
.
Additional rea-
sons for a shut-
down
When operating with derricking swing-away lattice:
– Different lifting capacities are released for the angles of inclination of 0°,
0 – 20° and 20 – 40°. As a result, lowering the swing-away lattice can result
in the SLI shutting down if the currently raised load in the recently set
angle range is not permitted.
– With the above angles of inclination, the swing-away lattice can be der-
ricked under load. If the current load is greater than that permitted for the
angle range, the lowering of the swing-away lattice is switched off by the
SLI.
– In the event of an SLI shutdown, the
Lower swing-away lattice movement is
disabled in addition to all other movements which increase the load
moment.
3.5.5 Procedure if the permissible wind speed is exceeded
•
Prior to and during crane operation, check whether the current wind
speed is lower than the maximum permissible wind speed.
• Make sure you follow the instructions for checking the wind speed;
à Lifting capacity table and Operating instructions GMK 4100/4100-L/5095.
If the maximum permissible wind speed is exceeded
No automatic shutdown occurs if the maximum permissible wind speed is
exceeded.
• Immediately stop operating the crane.
• Bring the truck crane into the rigging mode specified for the current wind
speed in the
Lifting capacity table.
G
Risk of accidents due to excessive wind speeds
If the current wind speed is higher than the maximum permissible wind
speed, stop operating the crane immediately and establish the correspond-
ing rigging mode.
This will prevent the truck crane from overloading and overturning.
