Safe, Environmentally-Conscious Design - Pick up SL6000 __

With primary and secondary overhoist prevention devices, this new safety system can prevent boom over-hoist at two stages. The primary stop function is activated when the boom or luffing boom approaches the critical angle-to-ground during hoisting. This new system monitors the angle-to-ground the boom, luffing boom or jib with a sensor, and swiftly alerts the operator of danger. For the luffing boom, the angle-to-machine is also monitored at this stage. The secondary stop function uses a device that monitors the angle-to-machine of the boom, luffing boom, or jib through a limit switch fitted to the boom and jib backstops. It stops the machine automatically to prevent it from working outside of the safety range, and once activated it cannot be cancelled.

This function is activated automatically when boom or luffing jib lowering, or boom hoisting is stopped by the over-hoist prevention system. It makes for a smooth stop and prevents the load from swinging sideways.

The automatic stop system prevents over-load, hook over-hoist and boom over-hoist. To deactivate the system, a two-stage release procedure is employed that uses a master key and separate switches. This makes it easy to supervise the use of the single key and prevent unauthorized release of the automatic stop system.


	• Function lock lever helps prevent accidental operation when the operator enters or leaves the cab.
	• One-way call supports the safety of onsite personnel (Optional)
	• External lamp for over-load alarm notifies surrounding workers of the load condition.
• Swing flashers and warning buzzer warn surrounding workers when the machine is swinging.


	The new layout eliminates winches on the base machine, providing more space for easier maintenance.

The standard KOBELCO internally gear swing bearing resists dust penetration and holds grease better than outer-cut bearings.


	Auto-greasers are fitted to the side frame of the crawlers to grease the lower rollers.

The large-capacity, super-fine filter is made of a high-performance filter medium consisting of glass fiber reinforced with steel wires. The replacement cycle is extended to four times longer than that of conventional filters to reduce lifelong operating costs.
