Demag double chain hoist: Two mechanically synchronised chain lead-offs for safely handling bulky loads

Double chain hoists are particularly suitable for handling long material or for operation with load bars. Demag offers solutions with two mechanically synchronised chain lead-offs that can lift and lower bulky loads in perfect balance. The load can also be asymmetrically distributed to meet special application needs.

The right double chain hoist for your application

LDC-D double chain hoists are suitable for higher speeds. The chain hoist can transport loads weighing up to 5,000 kg at 24 m/min. You can choose between a 2-stage or variable-speed control system and can use the chain hoist as a stationary, push or electric-travel unit, for example on our modular Demag KBK light crane system.

KLDC-D double chain hoists offer a short C dimension thanks to their low-headroom. This increases utilisation of the available space and loads weighing up to 2,000 kg can be lifted and lowered at 2-stage or variable speeds. KLDC-D chain hoists can also be operated as stationary units or with push or electric travel.

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.

  • Load capacities up to 5 t
  • Hook center distances from 550 mm to 3,200 mm
  • Lifting speeds up to 24 m/min
  • Available with 2-stage or variable speeds
  • Possible variants: stationary, traveling, for operation with KBK and for articulated trolleys
  • Asymmetric load distribution permitted

KLDC-D benefits

  • Low C dimension as for low-headroom design for optimum utilization of the available headroom
  • 2/4 lead-off position
  • Load capacities up to 2 t
  • Hook center distances from 400 mm to 4,600 mm
  • Available with 2-stage or variable speeds
  • Possible variants: stationary, traveling, for operation with KBK and for articulated trolleys
  • Asymmetric load distribution permitted

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

 

Low noise level

  • Reduced operating noise thanks to helical gearing in all gearbox stages
  • Smooth running characteristics thanks to high-quality gearing

Two chain lead-offs – tandem operation

Two chain hoists can be used in tandem as an alternative to mechanically synchronized double chain hoists for transporting long materials and car bodies, etc.

  • Parallel control from one control point
  • Tandem control (not synchronized control) for safe operation as a „group“ according to DIN EN 15011.
  • Individual chain hoists can be controlled by means of a selector switch.

Further KLDC-lead-off positions

KLDC-D double chain hoist

 

  • KLDC-D double chain hoist: low-headroom design, 3/4 lead-off position
  • Alternative lead-off positions depending on the size of the load handling attachments
KLDC-D double chain hoist: low-headroom design, 4/5 lead-off position

 

  • KLDC-D double chain hoist: low-headroom design, 4/5 lead-off position
