The indirect acting overload and underload protection measures the load by means of an sensor and switches off the
control path for lifting (in case of overload) or lowering (in case of underload).
The threshold values can be adjusted by means of adjusting screws:
Left turn:
Right turn: LED on
LED off Threshold values higher
Threshold values lower
The current status is shown as follows:
Overload ready:
Underload ready: LED on
LED off Overload trip:
Underload trip: LED off
LED on
Selection criteria of load sensing equipment
Type Integrated load sensor Suspension eye with load sensor
Benefit Additional protection against inner overload (chain
jam)
Additional protection when approaching the
gearbox with the hook tackle or hook block
Registration of all loads hanging underneath the
sprocket wheel;
Mass of chain does not falsify measuring result
Disadvantage Registration of all loads hanging underneath the
sprocket wheel;
Weight of long chain falsifies measuring result
No protection against inner overload
Cable between suspension eye and chain hoist may
be accident-sensitive
Applications
Mobile applications without overlong chains Fixed installation with load indication
