If you have a more detailed description of the model, its application, or specific questions about its operation or maintenance, I could provide more tailored advice or guidance on where to find the information you're seeking.
Note: The keyword includes "hot," which often signals that the user wants the latest, most popular, or actively searched information regarding downloading the manual, troubleshooting overheating issues, or finding high-demand spare parts for the Demag PK2N.
A hot gearbox is a silent killer. The Demag PK2N manual specifies synthetic oil (e.g., Demag Centralub or ISO VG 220). If you use standard grease, the gearbox will run 20°C hotter.
In 90% of urgent searches for the "demag pk2n manual hot," the user just wants the connection diagram. Here is a text-based representation of what the manual shows for a standard PK2N 230V pendant control:
| Terminal | Wire Color | Function | | :--- | :--- | :--- | | 1 | Black | Common (Phase) | | 2 | Brown | Up (Auf) | | 3 | Blue | Down (Ab) | | 4 | Green/Yellow | Earth | | 11/14 | N/A | Thermal contactor loop |
Note: Actual manual includes a full ladder logic diagram for the K1/K2 contactors.
To get the high-resolution, scalable vector PDF of this diagram, search Google for PK2N Schaltplan 636 771 42 (this is the actual Demag drawing number for the "hot" revision).
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.
If your search for "hot" implies that your unit is overheating or thermal protection is tripping, here is an analytical report on the likely causes:
Solution: The manual contains the duty cycle rating (e.g., FEM classification). If you are running the hoist at a "Hot" temperature (above 40°C ambient), you must derate the load. The manual explicitly states: "For ambient temperatures exceeding 40°C, consult Demag engineering."
The Demag PK2N is a workhorse, but it demands respect for its duty cycle. If your search for the "demag pk2n manual hot" was triggered by a shutdown due to heat, you now know to check voltage, brake rectifiers, and gearbox lubrication first. demag pk2n manual hot
Your immediate action plan:
Do not ignore the "hot" warning lights. A single thermal excursion can reduce the motor's insulation life by 50%. Use the manual, run it cool, and your Demag PK2N will outlast the next decade.

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 If you have a more detailed description of
Because many PK2N hoists are decades old, potential buyers should be aware of: Fatigue & Wear
: 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
frequently have these available, often pulled from working environments and load-tested. lekkerkerkerequipment.com ▷ Used Chain Demag PK2N-F for sale - Machineseeker.com
The Demag PK2N (often designated as PK2N-F) is an electric chain hoist typically used for lifting capacities of 250 kg to 500 kg. Below are the key technical specifications and manual resources for this model: Technical Specifications Lifting Capacity: 250 kg or 500 kg (model dependent).
Lifting Speed: Standard main speed of 5 m/min and precision (fine) speed of 1.25 m/min. Motor Power: Generally 0.5 / 0.13 kW. Power Supply: 380–400 Volt, 50 Hz.
Hook Path: Standard ranges include 3.5 to 5 meters, though it can be configured for more.
Weight: Unit weight is approximately 32.5 kg (net) for the hoist alone, up to 63 kg when paired with an electric trolley. Manuals & Spare Parts A hot gearbox is a silent killer
