Integrated directly into the drive train, this safety mechanism slips to protect the structural integrity of the hoist if it encounters an overload condition or hits the ultimate upper/lower hook positions.
The most common cause is lifting loads that exceed the rated capacity (e.g., using a 1000kg hoist for a 1200kg load). Even if the slip clutch doesn't immediately activate, the motor draws excess current to compensate, leading to rapid heat buildup. B. High Duty Cycle (Overworking) demag pk2n manual hot

Official manuals for legacy models like the PK2N can be difficult to source as single downloads. However, comprehensive operating instructions for Demag Chain Hoists often cover the general maintenance and spare parts lists applicable to the PK series. dual-speed (main/creep) configurations.
: The PK series was a pioneer for Demag, and many parts are interchangeable with other Mannesmann Demag components of the same era. Machineseeker Critical Considerations for Used Units
Locate the data plate on the side of the PK2 hoist body before searching for manuals, as the specific wiring diagrams change based on single-speed vs. dual-speed (main/creep) configurations.
