Extended Speed Range

Extended Speed Range

Benefits:

  • High-performance all the time
  • Maximized productivity
  • Significant time savings


Thanks to ESR (Extended Speed Range), the crane is a genuine performance artist and is always able to exploit its capability to the full.

The excess motor performance not used in part-load conditions (when hoisting smaller loads) is used to increase the maximum possible hoist speed thereby improving productivity to the optimum.

The "truck or racing car" - or something in between - calculation is carried out independently, fully automatically and continuously. This makes safe and rapid load handling permanently available.



Micro Speed

Micro Speed

Benefits:

  • Precise load positioning
  • Prevents unwanted acceleration
  • For hoist, trolley and crane motion
  • 1% - 99% of full motion speed


MICRO SPEED is the key to precise working when a gentle touch is called for. An easily operated On/Off switch on the control system is used to reduce the maximum speed here, ensuring the required precision and control of the load.

The speeds for hoist, long and cross movements can be defined differently and each set to between one and ninety-nine percent of the maximum speed.

Safety can be considerably enhanced and inadvertent accelerations can be prevented by this system, particularly for heavy loads.


Slack Rope Prevention

Slack Rope

Benefits:

  • Reduces risk of damage to crossbeams, ropes, slings and sheaves
  • Optimizes load handling and loading cycle
  • Enhances productivity and safety


The SLACK ROPE PREVENTION option lets the hoist detect itself when the load has reached the ground and automatically stop the lowering process.

In addition to the increased productivity thanks to optimised set-down, this significantly enhances safety and considerably reduces the risk of damage to the rope or on the pulleys, particularly when crossbeams are in use.


Inching

Inching

Benefits:

  • Precise load positioning
  • Reduced risk of collisions
  • For hoist, trolley and crane movements
  • Enhanced safety


The load can be positioned with extreme pinpoint precision by using predefined steps, the size of which is freely selectable between 2 and 100 mm.

Once INCHING is selected on the control system, the hoist moves - step by step - only in the direction selected on the joystick and for the distance limited by INCHING.


Restricted Load

Restricted Load

Benefits:

  • Protects the building structure against overload
  • Robust and reliable limiting of load ranges

It is not always possible to fully exploit the full capability of the hoist over the crane's entire movement range.

The RESTRICTED LOAD option ensures that these restrictions on loading are observed and protects the building structure against damage.

The individual load ranges are bounded by robust solenoid switches, whether for cross or long travel, thereby always guaranteeing maximum safety.


Sway Control

Sway Control

Benefits:

  • Maximized movement speeds
  • Minimized load-sway
  • Higher load positioning accuracy
  • Increased safety


Swaying loads do not only represent a major hazard, but also cause considerable time losses in precise load placement.

Sway Control, the electronic load-sway protection, permits efficient and safe load handling thanks to optimal crane movements. Because the load is easier to control, the crane operator can concentrate on the load and not just on the crane.

Load peaks caused by swaying are also prevented. The stresses on both the mechanical and electronic components are reduced resulting in the crane requiring less servicing and having a longer service life.


Load Floating

Load Floating

Benefits:

  • Longer lifetime of crane’s steel structure, crane runway, mechanical components, etc.
  • Makes the load movement more stable and safe
  • Protects fragile loads


The LOAD FLOATING option permits faster and smoother switchover between hoisting and lowering.

In this function the load is held exclusively by the hoist motor for a selectable period of time (generally 3 to 5 seconds). The motor is supplied with precisely the torque required while the brake remains open to stabilise the hoisting height, without hoisting or lowering.

Thanks to the gentle movements, the service life of the steel structure, the crane rails and the mechanical components is extended, just like that of the ropes, crossbeams and slings. Stabilisation in load handling protects fragile loads and enhances safety at work.


Shock Load

Shock Load

Benefits:

  • Longer lifetime of crane’s steel structure, crane runway, ropes, crossbeams and slings
  • Safe and stable load handling
  • Protects fragile loads


Shock loads cannot just cause damage to the load, they can also significantly increase the stress on all the components involved in the hoisting process.

When the Shock Load option is active the load is monitored by the frequency inverter and the hoisting process is automatically slowed down in the event of rapid load changes.

Thanks to this controlled process, the load is hoisted smoothly and stably and safety is appreciably improved.


Tandem

Tandem

Benefits:

  • Simultaneous start and stop of hoisting and trolley travel
  • Simultaneous control of up to 4 trolleys on one crane
  • Load summation and high safety in operation


The system is used where loads must be transported with pinpoint accuracy by a number of hoists at the same time.

Up to four hoists can be controlled by the crane operator in tandem operation. The hoists are controlled to start and stop the hoisting process at the same time.


Synchronisation

Synchronisation

Benefits:

  • Permanent monitored and synchronized hoisting also for unbalanced loads
  • Minimized risk of accidents
  • Increased productivity and safety


More can be achieved by working together. This is also true for joint hoisting of loads with two hoists on one gantry.

The SYNCHRONISATION option provides optimal, permanent synchronisation thanks to constant monitoring.

The hoists can be controlled absolutely synchronously and precisely through one control system, even if the load is asymmetric, thereby guaranteeing smooth and safe handling of long goods at all times.

The hoisting speed measured by the encoders is continuously synchronised between all the hoist motors. The data detected is exchanged between the hoists over a CANbus connection in each of the frequency inverters. This means that no separate control unit is required.


Cranes in Tandem

Cranes in Tandem

Benefits:

  • The long and cross travel, and also the hoisting and lowering movements, can be synchronised
  • Collision safety
  • Frequency inverter functions and overload protection

Hazardous situations can always arise as soon as one of the cranes involved unexpectedly slows down or comes to a halt when cranes are being used together at the same time. Electronic crane locking prevents precisely these situations. All the relevant data on the crane systems is continuously monitored and exchanged by wireless.

Relays in an additional control cabinet on each crane take care of feedback and communication between the two systems.


Crane Intelligence
control options

The individually configurable Crane Intelligence, which incorporates electronic monitoring and control aids, can be used to make transporting loads safer and more productive and to optimise costs.

Even the control actions of experienced crane operators can be further perfected by this "second brain", and in this way the capabilities of the crane as a whole can always be fully called upon while remaining kind on load and technology.

This does not just reduce operating and maintenance costs, but also significantly reduces the risk of an accident thanks to the intelligent load handling methods. Controlled travelling and positioning are a guarantee of productive load handling.
