For the chain hoists GM2 and GM4:
─ The suspension bracket can be rotated 90°.
For the chain hoists GM2, GM4 and GM6:
─ The chain hoist is equipped with direct control
400 V / 50 Hz as standard.
─ Only for direct control without electric trolley
travel and for direct control with electric trolley
travel: The chain hoist has three-pole
protection with integrated fuses.
─ The chain hoist can be equipped with
electronic control using maintenance-free
semiconductor technology with 48 V control
voltage (optional).
For chain hoist GM8:
─ The chain hoist is equipped with electronic
control using maintenance-free semiconductor
technology with 48 V control voltage.
For chain hoists with electronic control:
─ The chain hoist can be equipped with
ABURemote AC radio remote control
(optional),
For chain hoists with a mechanical hoist limit switch:
─ The chain hoist can be equipped with a
mechanical hoist limit switch (optional).
─ An upper and a lower switching point can be
set with the mechanical hoist limit switch.
When the load hook reaches one of the
switching points, the chain hoist brakes and
halts.
─ The switching points of the mechanical hoist
limit switch can be used in combination with a
contactor control as a hoist limiter.
─ The switching points may be triggered during
normal operation. If the microswitches of the
hoist limit switch wear out due to regular use,
the friction clutch of the chain hoist serves as
an emergency end stop device.
For chain hoists with an electronic hoist limit switch:
─ The chain hoist can be equipped with an
electronic hoist limit switch with teach-in
function (optional).
─ An upper and a lower switching point can be
set with the electronic hoist limit switch. When
the load hook reaches one of the switching
points, the chain hoist brakes and halts.
─ Optionally, an additional switching point can be
located between the two switching points as an
intermediate switching point. If this additional
switching point is programmed, the chain hoist
brakes as soon as the load hook approaches
the intermediate switching point and halts
there. The switching point can then be overrun
by releasing the button for lifting/lowering and
pressing it again (stop-and-go).
─ The switching points on the electronic hoist
limit switch are programmed with a supplied
teach-in module, which is plugged in instead of
the pendant control.
Alternatively, a pendant control with an
additional teach-in button is also available.
With ABURemote AC, the teach-in function can
be operated remotely (optional).
