Smartlift / Smartdrive Controllers

What is SC Smartlift / Smartdrive?

SC Smartdrive and SC Smartlift represent a quantum leap in crane drive technology. A microprocessor allows the infinitely variable control of hoist, travel and traverse motor speeds by means of a digital frequency and electronic braking module. Each of the systems helps to reduce load swing and provide precise crane movements.

A frequency inverter is an electronic device, which converts constant voltage and frequency onto variable voltage and frequency. The crane drive characteristics are therefore programmable to suit the application

  • Programmable speeds with all motions.
  • SC Smartlift employs closed loop vector technology utilising a digital encoder fitted to the motor shaft.
  • SC Smartdrive employs open loop vector technology.
  • Programmable acceleration and deceleration.
  • Very slow minimum speed ranges (10:1 as standard with other options upon request) for precision handling.
  • Multiple speeds available when used with multi-position controllers.
  • Smooth starting extends the life of the mechanical drive components.
  • Reduced starting currents extends electrical component life.
  • Electronic braking reduces the mechanical brake wear.
  • User friendly LCD display on microprocessor.
  • Diagnostics facilities, including fault history available on all frequency inverters.
  • No speed variation between "no load" and "full load".
  • "Ultralift" high-speed light hook option is also available with SC Smartlift. Typically used with very slow speed hoist motions.

Smartlift and Smartdrive have infinitely variable speed control and may be programmed to achieve customised solutions in special applications and part of an integrated system of controls. For total eradication of any load swing, see the XY-Zero Swing Prevention System.

XY-Zero Control

What is XY-Zero?

  • XY-Zero is an optional software package fitted to the crane, which is designed to totally eradicate load swing caused by travelling movements of the crane.
  • The software can be fitted to new or existing pendant, radio or cab controlled cranes.
  • Standard software is suitable for heights of lift up to 30 metres.

How does XY Zero works?

The XY-Zero software is installed on a frequency inverter or PLC controlled drives and can be used in conjunction with one or both of the crane axis (travel or traverse).
Proximity switches are mounted onto the hoist unit, which provide a constant feedback signal to indicate the hook height at any given point. As the crane motions are operated, the XY-Zero software calculates the predicted swing movement on the load. The crane's travel and traverse movements are then automatically modified to eliminate any load swing. This provides the operator with greater control over the crane, allowing faster crane cycle times, increasing efficiency.

Using Slings, Chains or Lifting Attachments

When lifting using different slings, chains or attachments, the operator adjusts the height correction switch on the crane controller to suit the particular attachment. The multi-position rotary switch uses the input figure for the length of the attachment to fine -tune the pendulum length. This keeps the load steady, eliminating any double pendulum effect that may normally occur.

XY-Zero reduces crane cycle times by a much as 50%

  • Safely allows much faster speeds
  • Increases operator efficiency
  • Soon pays for itself
