New-generation SLX chain hoist from Konecranes speeds up the work cycle, eases maintenance work, improves security and doubles the service life of the hoist
Konecranes has introduced a new-generation, cutting-edge SLX chain hoist that aims to meet customer requirements. The new chain hoist is an advanced version of, CLX chain hoist, a proven performer in itself. Not only does the SLX chain hoist contain new technology, it also incorporates new inverter in hoisting to speed up and facilitate operations by the end-user.
The new, steel-framed and sturdy SLX chain hoist is particularly suitable for individual workstation applications, such as assembly cells, in the workshop industry. Other applications include jib cranes and EOT cranes. The particularly sturdy structure of the hoist enables a larger load capacity, while doubling the lifecycle of the machine compared to other hoists. The durability of the lift chain was also a key element in the design. The patented chain sprocket dramatically improves the durability of the chain.
The chain sprocket’s transmission has been completely redesigned. The new, oil lubrication-based transmission reduces the operating temperature, enabling increased power. Furthermore, the new transmission is maintenance-free and much quieter to operate. It increases the speed ratio between low and fast speeds. The new 6:1 speed ratio enables a safe, accurate installation speed and an extremely fast movement speed. The wider speed range makes the SLX chain hoist 25 per cent faster than normal hoists, which helps speed up the work cycle and improves work efficiency.
All components that require maintenance are easily accessible and do not require the removal of any parts. All electronics are located compactly on reliable circuit boards, minimising the amount of internal wiring compared to the previous model. The new design solutions make the maintenance work significantly easier and faster.
Safety functions have been integrated into the standard characteristics of the hoist. For example, the brake and the clutch have been installed on the same axle, which prevents load from dropping even if the clutch breaks down. This feature takes the safety of the SLX chain hoist to a completely new level.
• Shock load absorption: Reduces effect of a sudden shock load• Electronic overload device: With strain gauge sensor overload can be detected easily• Programmable limit switch: Two-step upper and lower, only stop function, plus emergency upper and lower limit switchProgramming: Hook is taken into desired position and parameters can be set• Polygon dampening: Reduces vibration of the load by 40 per cent• Clutch control/brake control:  Stops operation when speed in the secondary side of clutch is below set limit  Ensures that brake is open when motor is activated  Checks that brake is closed when motor is not running.
The new-generation SLX chain hoist has been designed to be energy efficient, and it meets all the requirements of the RoHS Directive. The hoist’s circuit boards do not contain any hazardous lead as soldering material, just one example of the hoist’s eco-friendly features.
