Safety measures
A variety of mechanical, electronic and hydraulic safety and alarm
devices are widely used to ensure the safe use of the machine.
Safety devices include torque limiter, slewing lock, boom
anti-tilt, lifting height limiter, boom angle limiter, level gauge,
slewing warning and hydraulic system overflow valve, balance valve,
hydraulic lock, etc.
Mode switching
You can switch between installation mode and working mode. In
installation mode, the overwinding prevention device, boom limiter,
torque limiter, etc. are not functional, which is convenient for
crane installation.
In working mode, all safety devices are functional.
Emergency Stop
With emergency stop function, all actions can be stopped quickly in
an emergency.
Anti-misoperation function
The handle has an anti-misoperation function. A safety protection
switch is set on the front side of the handle. When this switch is
not pressed, all action signals are shielded and the handle does
not work to prevent misoperation.
Anti-overwinding function
The overwinding device is set at the boom head to prevent the wire
rope from overwinding. When the hoist reaches a certain height, the
overwinding indicator light on the display will light up and the
hoisting action will stop automatically.
Anti-over-releasing function
The lifting mechanism is equipped with a three-turn protector to
prevent the drum from over-releasing when releasing the rope. When
there are only three turns of the hoisting wire rope left, the
over-releasing indicator light on the display will light up and the
lowering action will stop automatically.
Pawl lock function
It is equipped with a ratchet locking device to lock the luffing
winch to ensure that the boom is safely parked when not in
operation.
Slewing lock function
It is equipped with a slewing locking device, which is used for
parking and storing the crane when it stops, and for locking the
upper vehicle's slewing.
Anti-tilting function
The main boom and jib bracket are equipped with an anti-tilt device
to prevent the boom and jib bracket from tilting backward.
Lifting boom angle limit function
When the main boom reaches the specified angle, the lifting is
stopped and is controlled by the torque limiter and the travel
switch. When the elevation angle of the main boom is less than the
specified angle, the falling is stopped and is controlled by the
torque limiter and an audible alarm is issued.
Hook anti-drop function
All hooks are equipped with anti-drop plates to prevent the slings
hanging on the hook heads from falling off.
