Demag PK2N (often seen in its dual-speed version ) is a classic industrial electric chain hoist known for its reliability and "plug-and-play" simplicity Used machines
. Below is a summarized "cheat sheet" for operation, technical specs, and essential maintenance gathered from available manuals and technical data. 1. Key Technical Specifications
The PK2N-F is typically configured for light-to-medium industrial lifting Machineseeker Lifting Capacity : 250 kg for a single chain fall (1-leg) or for a double chain fall (2-leg) Machineseeker
: Dual-speed operation (F4) is standard, typically featuring a main speed of and a precision creep speed of 1.25 m/min Machineseeker Motor Power : 0.5 kW for main lifting and 0.13 kW for creep speed Used machines Power Supply : 400V (or 380V), 50 Hz Used machines Brake System
: Conical brake motor where the brake is released by the axial displacement of the rotor when energized 2. Essential Maintenance Procedures
For long-term reliability, follow these manual-recommended checks: Brake Adjustment
: The most critical maintenance task. As the brake lining wears, the axial displacement of the rotor increases. How to check
: Observe the axial movement through the motor's inspection window Adjustment demag pk2n manual hot
: Remove the back cover, loosen the socket cap screws, and turn the adjustment disc counterclockwise
(standard right-hand thread) to move the brake lining outward and compensate for wear Chain & Lubrication
The load chain must be lubricated regularly to prevent premature wear.
Before installing a new set of parts or gears, it is recommended to soak them in reducer oil for one hour
: The specified rotor/stator air gap value for the PK 2 series is 3. Safety & Troubleshooting Emergency Stops
: The unit will not operate if the emergency stop is locked or if there are active lifting/lowering commands Loose Connections : Always use self-locking nuts
for structural connections; never replace them with standard nuts as vibrations can cause them to loosen Slipping Clutch
: The clutch and brake are integrated for safety. In newer models, these are maintenance-free for up to 10 years, but for older PK units, they should be checked during annual inspections Handling Control Solutions 4. Sourcing Manuals and Parts

Demag, a well-known brand in the crane and hoist industry, offers a variety of products, including electric hoists like the PK series. The "PK2N" likely refers to a specific model within their product lineup.
The PK2N uses an AC brake rectifier (often Type BGE 1.5). If this rectifier shorts, it holds the brake open magnetically, but the coil draws constant current. The coil burns "hot" within 60 seconds.
Manual Fix (Page 12 - Brake Section):
The PK2N is typically equipped with a thermal overload protection switch inside the terminal box or motor winding.
The PK2N is often wired for 400V but supplied with 415V. The manual states a tolerance of ±5%. If voltage is too high, current drops, but insulation stress rises (heat). If voltage is too low (e.g., 380V on a 400V setting), current spikes—causing extreme heat.
