HOOK:
DEMAG QUADRO CHAIN HOIST FOR
A BROAD RANGE OF APPLICATIONS
Fitted with four load hooks, the Demag LDC-Q
quadro chain hoist allows different load handling
attachments to be lifted and transported at the
same time. The available LDC-Q sizes enable
loads weighing up to 3.2 ton to be handled safely
and efficiently.
The Demag LDC-Q quadro chain hoist, a series
hoist unit from Demag’s DC range that has a
successful track record all over the world, can be
used for a wide variety of handling requirements
in production and logistics applications. Equipped
with four load hooks, LDC-Q units can handle and
transport customer-specific load handling attachments
or flat components and feed materials to
the relevant workstations.
The basis for this broad range of applications
is the technology offered by the LDC-D double
chain hoist and some dedicated characteristics.
For example, these include a design that combines
two double chain hoists which have only
one drive, which is a special technical feature. This
means that only one chain hoist motor transfers

DESIGN WITH FOUR LOAD HOOKS
power to the other three chain lead-offs of the
Demag LDC-Q quadro unit via corresponding
connections. Mechanically synchronised hook
lead-offs provide for uniform and precise load
handling. This arrangement enables loads with an
asymmetrical weight distribution up to a ratio of
70:30 to be picked up without any problems.
ProHub integrated variable speed control, which
is a feature unique to Demag chain hoists, also
permits rated speeds of up to 90% higher in the
partial load range. Operators can utilise sizes
DC 10 and DC 25 for handling loads weighing
up to 3.2 ton. The Demag LDC-Q quadro chain
hoist offers benefits for safe and efficient lifting.
Operation of the control unit with low voltage (24
V contactor control) as well as smooth starting
and braking for low load sway are also significant
factors. Further safety-related functions satisfy at
least Performance Level C and Category 2 to EN
ISO 13849-1.
Besides safety, service is also of major importance.
The generously dimensioned slipping
clutch and gearbox, which is maintenance-free for
up to 10 years, as well as fast and simple maintenance
of individual components thanks to its
modular design, help to make the Demag LDC-Q
quadro chain hoist easy to service. These are
all important aspects that minimise downtimes
and extend the unit’s service life for improved
productivity.
For control of the Demag LDC-Q quadro chain
hoist, operators also benefit from DSC/DSE
control pendants with their low-fatigue actuation
force for improved ergonomics. To meet specific
ergonomics needs, operators can choose between
radio controls or cable-connected control
pendants that can be integrated into stationary
control units.
And ultimately, 2D and 3D geometry models
in the Demag designer tool give owners the
opportunity to view a potential solution and its
precise arrangement in their existing building and
machinery infrastructure already at the pre-planning
stage.
