NOVA

Electric wire rope hoists for loads of up to 80 Tonne

  • Optimum utiliastion of space

Compact installation dimensions and optimum approach dimensions, minimum hook dimensions

  • Precise and safe work

Minimum lateral hook movements and low swing thanks to smooth load movement with frequency inverters

 

  • Low maintenance costs

The brake designed to extend the lifetime, the larger drum diameter of the rope drum to protect the load rope, the hoist gear libricated to extend the lifetime and the smooth cross travelling with the frequency inverter reduces material wear and tear

Maximum cost effectiveness and optimum utilisation of space

  • Loads of up to 80 Tonne
  • Single hoist or as a crane kit
  • Single or double girder trolley or foot-mounted hoist
  • Low lateral hook movement
  • Compact installation dimensions
  • Optimum approach dimensions
  • Stepless cross and long travelling
  • Ambient temperature –10C to +40C

 

 

 

Perfect utilisation of space and almost vertical lifting guarantee so that work is carried out precisely and safely

SWF have increased the size of the drum, making everything else smaller

The main feature of the SWF NOVA electric wire rope hoist is the extremely large diametre of the rope drum, which provides first class protection of the rope, but there are also other features which guarantee safe and very cost-effective use.

NOVA does away with load swinging and lateral hook movement

NOVA lifts the load with virtually no lateral hook movement at all. Swinging of the load is prevented and secure handling is guarenteed. At the same time, this can help reduce the costs of the crane design.

NOVA adapts itself to your building

NOVA offers the best approach dimensions and the smallest installation dimensions in the electric wire rope sector. This enables the optimum utilisation of space and reduces building costs.

Frequency inverter technology for efficient hoisting

The use of frequency inverters for the hoisting process increases productivity. This leads to an extended lifetime of motors and brakes as well as cost savings for maintenance work and spare parts. Furthermore, the hoist works in a far more efficient manner than a conventional contactor-controlled solution.

  • Safe hoist speeds for the smooth handling of heavy loads
  • Quick hoist speeds with low loads increase productivity
  • Reduced energy consumption
  • Working time is reduced thanks to more effective and quicker working with load-dependant speed regulation
  • Less wear and tear due to reduced mechanical load
  • Reduced downtimes
  • Reduced operating costs

 

Standard Equipment:

  • Load-dependant speed regulation (ESR)
  • Duty cycle 60%
  • Overheat protection
  • Insulation class H
  • Protection rating IP55
  • Bearing sensor to monitor the roatating speed (A motor) or encoder to regulate rotating speed, closed loop control (S motor)
  • External fan (S motor)

 

An innovation which sets economical standards

A-motor with HoistMaster 2p or HoistMaster 4

When using A-motor in combination with a HoistMaster 2p the hoist inverter is installed in the bridge panel. In some hoists the hoist inverter HoistMaster 4 can be directly integrated into the hoist panel.

An A-motor operates, compared to polemotors, with only 50% lifting power and thus reduces energy costs by around half. Despite the halved hoist motor power, the load-dependant speed regulation (ESR) enables work to be carried out more effectively and quicker with an average industrial crane workload:

  • Triple the nominal speed at 10% partial load
  • Double the nominal speed at 40% partial load
  • Standard nominal speed at 100% full load

The A-motor technology is a cost-effective solution, because of its favourable acquisition costs and savings in operation, which pay for themselves very quickly.

 

S-motor with HoistMaster 2p

When using an s-motor in combination with a hoist inverter HoistMaster 2p, the hoist speed and hoist motor performance are compatible with the standard speeds. Thanks to the separate fan that comes as standard on the hoist motor, the hoist can also be operated at full load for a very long time at a slower hoisting speed.

The encoder constantly regulates the rotating speed of the hoist motor and thus guarentees that the load is transported safely and accurately even at very low hoisting speeds (only 1% of the nominal speed)

The load-dependant speed regulation (ESR) enables:

  • 5 times the nomina speed at 25% partial load
  • Standard nominal speed at 100% full load

The S-motor together with hoist inverter HoistMaster 2p offers the possibility of connecting up to 4 hoists together via an optical cable and to synchronise the joint hoist lifting process.
