ZX HOIST: the next generation.
 
Performance through evolution and innovation

The new ZX hoist sets the benchmarks in the crane industry. It provides a series of unique benefits for the user. ZX epitomises intelligent design - for easy load handling - impressive performance - exceptional safety levels.

We invite you to compare the following hoist specification with any in the world and we think you will agree ZX represents unbeatable value for money and great investment.

“A hoist for tomorrow’s world in which only the most productive will prosper. ”
 

Operating and safety features

  • Precision engineered hoist gearbox with all gears oil immersed in a cast Aluminium gearbox case.
  • Trolley reaction roller - avoids the need for a counterweight – increases the life of the rolling surface – reduces shipping and transport costs.
  • Capacity restrictor measures the load in the hoist mechanism – protects the operator and the machine - Easily adjusted - does not reduce height of lift.
  • Heavy duty rope guide ensures positive rope scrolling – designed to prevent “slack rope” conditions - specially selected self-lubricating material.
    Heavy duty two-speed hoist motor with built in protection against over-heating – fitted externally for improved ventilation and easy access.
  • Direct drive trolley with flangeless traverse wheels and side rollers for high durability and reduced wear – sealed for life maintenance free bearings in hoist the trolley frame.
  • Superior load safety - low maintenance long-life hoist brake – acts on the gearbox shaft not motor shaft - mounted externally for improved ventilation and cooling – asbestos free brake linings - automatic braking in the event of power failure.
  • New ergonomic bottom block design for improved safety and handling – sealed for life maintenance free bearing fitted in all sheaves - robust cast aluminium sheave covers – spring loaded safety catch.
  • High strength galvanised wire ropes for maximum corrosion protection – compact strand structure with improved tensile strength.
  • Heavy duty fan cooled trolley motor.
  • Easily adjustable overhoisting and overlowing limit switches to suit individual applications.
  • IP55 steel electrical control cubicle – quick release plug and socket connections – hours in service meter – phase failure relay protects the hoist against incorrect phase sequence, phases failure and connection to over or under voltage – mechanical over-speed switch for improved operator safety - fully ferruled and identified wiring.
 
Optional features / equipment
  • Fast and extra fast hoist speeds for shorter handling times.
  • Two speed travel using 8:2 pole motor(s) or Frequency
  • Special Voltages.
  • One step traverse limit switches (slowdown or stop).
  • Two step traverse limit switches (slowdown and stop).
  • Push-button pendant on hoist.
  • Visual or audible overload warning.
  • Second hoist brake mounted on hoist motor.
  • Standby heaters on hoist and trolley motor.
  • Standby heaters in control panel.
  • Frequency inverter on hoist motor.
  • Non-standard traverse speeds.
 
SC Smartdrive Technology.
The New ZX hoist incorporates SC SMARTDRIVE, the latest, most advanced traverse speed control technology to give the superior performance you might expect from a world leader. ZX beats the competition by employing a full frequency inverter and current vector control for minimum load swing and easy, more accurate load positioning for greater safety and productivity.
 
 
SC Smartlift and SC Smartdrive Speed Controllers
What is SC Smartlift & SC 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.
 
Standard features - SC Smartlift and SC Smartdrive
 
  • 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.
