LDC-Q quadro chain hoist

Mechanically synchronised

Demag LDC-Q quadro chain hoist: Four mechanically synchronised chain lead-offs

Four attachment points are a good solution for transporting customised load handling attachments or loads weighing up to 3,200 kg that have a large surface area. With its LDC-Q quadro chain hoist, Demag can supply a chain hoist with four mechanically synchronised chain lead-offs that can lift and lower loads evenly and with high precision. Its special feature is a chain hoist that drives all four chain lead-offs. With high safety and reliability. LDC-Q units allow work to be performed under suspended loads according to accident prevention regulation BGV D8+.

Precision engineering by Demag

Smooth cross-travel starting and braking motions for low-sway load handling. A choice between 2-stage or variable lifting speeds rounds off a convenient and precise lifting solution with the Demag LDC-Q.

Durable components for uncompromising cost-efficiency

The components installed in the DC chain hoist range are selected for their longevity. The generously specified gearbox allows for FEM classification up to 4m and, therefore, 6,300 hours of operation for demanding applications.

Customer benefits at a glance

Safety

Low-voltage control pendant thanks to 24 V contactor control system
Safety-related functions satisfy at least Performance Level c and Category 2 to EN ISO 13849-1

Minimum load sway

Smooth cross-travel starting and braking motions for low-sway load handling
Speeds and acceleration/braking rates can be modified by means of the control pendant, if required

Long service life

Generously specified gearbox. 2m+ (1,900 hours) for main load capacities and up to 4m (6,300 hours) for demanding applications
All sub-assemblies of the chain hoist are rated for a long service life, even under the most demanding conditions

Temperature range

Reliable operation from -20 °C to +45 °C without any reduction in the duty factor
Operation also possible up to 60 °C and more

Ergonomics

Length of control cable or position of control pendant can be adjusted without the need for any wiring
Length of control cable that is not needed can be stored under the service cover

High-performance motor

Hoist motor has large safety reserves to provide for reliable operation for many years
Can be used for switching cycles way beyond usual market levels

Pro-Hub function

Up to 90% higher rated lifting speed in reduced load range

Easy to service

Gearbox & slipping clutch maintenance-free for up to 10 years
Brake maintenance-free for up to 10 years (up to 5 years for DC 10–25)
Simple and rapid maintenance and repair of individual components thanks to the modular chain hoist design – cuts any downtime to a minimum

Variable speeds

Valuable and sensitive parts can be moved and positioned more smoothly and reliably
Variable button characteristic like a car accelerator pedal

Status display

Display for elapsed operating time counter and operating statuses
Always up-to-date for service purposes

Slipping clutch monitoring

Harmful continuous slipping eliminated thanks to speed monitoring
Reliable protection against extreme overload
Load securely held in any operating situation and cannot drop while hoist is at standstill, since brake is arranged in front of the slipping clutch in load-bearing arrangement
