model) is a classic industrial electric chain hoist, widely recognized for its robust construction and longevity. While older units are common on the used market, they remain a staple in many industrial environments due to their simple, serviceable design. Demag Cranes Core Specifications
is typically configured for heavy-duty industrial lifting with the following standard specs: Load Capacity : Generally rated for 500 kg (approx. 1,100 lbs) in a 2-fall configuration or in a 1-fall setup. Lifting Speeds : Often features two speeds—a main lifting speed of 5 m/min (approx. 19.2 FPM) and a fine/precision lifting speed of 1.25 m/min (approx. 4.8 FPM) Power Supply : Standard industrial 380-460V, 3-phase operation. : The unit itself typically weighs between 32 kg and 50 lbs depending on the specific model and accessories. www.werktuigen.com Key Features & Performance Durability
: Users and refurbishers highlight that these hoists were built to last, with many units from the 1980s still in "ready to use" condition today. Serviceability
: The design allows for the gearbox and slipping clutch to be relatively maintenance-free for long periods (up to 10 years in modern equivalents like the DC series), and internal components like contactors are easily accessible for inspection. Precision Control
: The two-speed motor allows for both fast movement and extremely precise positioning, which is critical for delicate assembly work. Interchangeability
: 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
Because many PK2N hoists are decades old, potential buyers should be aware of: Fatigue & Wear demag pk2n manual hot
: Units exceeding 35–45 years may show fatigue in load-bearing frames. Inspections should look for cracks or motor rotor loosening. Parts Availability
: While they are "absolute workhorses," the availability of original spare parts has decreased over time, which can lead to longer downtimes if a major component fails. Refurbishment Value
: There is a strong market for refurbished units. A complete revision typically includes stripping the frame, replacing all wear parts (bearings, gaskets), and installing new cabling. Demag Cranes Where to Buy You can find used or refurbished Demag PK2N
hoists through several specialized industrial marketplaces and retailers: Industrial Marketplaces : Sites like Machineseeker often list these units starting around $530 to $600 USD Refurbished Specialists : Companies like Lekkerkerker Dairy & Food Equipment offer fully refurbished units with warranties. Secondary Market : Sellers on

The Demag PK2N (often designated as PK2N-F for two-speed models) is a classic electric chain hoist known for its reliability in industrial lifting. The "manual" you are looking for typically covers maintenance, spare parts, and technical specifications for units with capacities ranging from 250 kg to 500 kg. Key Technical Specifications
Load Capacity: Standard models handle 250 kg (single fall) or 500 kg (double fall). Demag PK2N (often seen as the Go to
Power Supply: Usually operates on 220/380V or 460V, 3-phase at 50/60Hz.
Lifting Speeds: Often features two speeds (e.g., 5/19 FPM), allowing for both rapid movement and precise positioning.
Control: Uses a low-voltage contactor control (often 24V) for operator safety. Maintenance & Operation Highlights
Based on official Demag Operating Instructions, key maintenance points include:
Brake Air Gap: The critical rotor/stator air gap for the PK 2 is typically 0.30 mm.
Lubrication: Reducer components should be soaked in gear oil for one hour before installation to ensure longevity.
Safety Features: Includes emergency stop buttons, slipping clutches to prevent overloading, and limit switches for upper and lower hook positions. Method 1: The Official Konecranes/Demag Portal (Fastest)
Chain Care: Regular lubrication of the round steel chain is required to prevent "stiff links" and premature wear. Finding Manuals and Parts Demag DKUN Hoist Operating Manual | PDF - Scribd

Method 1: The Official Konecranes/Demag Portal (Fastest)
- Go to Konecranes.com (Demag is now part of Konecranes).
- Navigate to "Services" -> "Product Documentation."
- Search
PK2N. - Pro tip: Filter by "Electrical Schematics" and "Spare Parts List." These are the two "hottest" documents.
Step 1: Check the Nameplate vs. Supply Voltage
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.
From the manual (Section 3.1):
- Wire the motor according to the terminal diagram inside the terminal box.
- For prolonged high ambient temperatures, upgrade the thermal relay to Class 20.
Q3: Why is the "hot" manual search so popular right now?
Demand for spare parts (brushes, clutches, contactors) has surged because companies are refurbishing old PK2N units rather than buying new Chinese hoists due to supply chain delays. The "hot" manual is the refurbisher's bible.
Part 1: Why the "Hot" Search? Understanding Thermal Overload in the PK2N
Before we discuss the manual, let's address the "hot" aspect of your search. The PK2N is a compact hoist (typically 125kg to 500kg capacity). Its motor is designed for intermittent duty.
