Dane techniczne wciągnika łańcuchowego Demag DC

Niezależnie od tego, czy jesteś inżynierem określającym sprzęt, kierownik ds. zakupów podejmujący decyzję o zakupie, lub specjalista ds. konserwacji, który chce lepiej zrozumieć Twoje maszyny, knowing the technical specs is key. This article provides a comprehensive overview of the core technical specifications that make the Demag DC-chain hoist a powerhouse in its class.

Overview: The Hallmarks of the Demag DC Series

The Demag DC hoist is an electric chain hoist characterized by its modular design, which allows for incredible versatility. It can be configured for simple hook-mounted operation, integrated into a single-girder crane (DK), or used in a double-girder crane (DZ) setup. Its defining features include a compact design, high-duty cycles, and the legendary Demag commitment to safety and durability.

Core Technical Specifications (General Range)

While specific models vary (NP., DC 100, DC 200, DC 300, DC 500, DC 1000, itp., where the number indicates the capacity in kg), the following specifications cover the general range of the standard DC series.

1. Pojemność podnoszenia

• Range: The series typically covers capacities from 100 kg up to 5000 kg (0.1 Do 5 tonnes), with some specialized models extending beyond.

2. Prędkość podnoszenia

• Standard Models: Lifting speed is dependent on the capacity and motor type (voltage/frequency).
  • For 400V/50Hz models: Speeds range from 2.0 Do 10.0 metrów na minutę (m/mój). A common speed for a 500 kg model is around 8 m/mój.
  • For 460V/60Hz models: Speeds are approximately 20% higher due to the increased motor frequency.
• Dual-Speed (Dual Frequency) Option: Many models offer a dual-speed feature, providing a precise, slow-speed setting (often 1/10th of the main speed) for accurate load positioning.

3. Prędkość podróży (Zmotoryzowany wózek)

• When equipped with a Demag motorized trolley, travel speeds typically range from 10 Do 20 m/mój, depending on the hoist capacity and trolley model.

4. Wysokość podnoszenia / Chain Fall

• This is highly customizable. The modular design allows for virtually any lift height to be specified. The standard chain container can accommodate significant lengths of chain.

5. Hoist Motor

• Typ: Three-phase squirrel-cage motor.
• Cykl pracy: Designed for high duty cycles (often up to 60% ED – Duty Cycle Class FEM 2m / H3), making it suitable for intensive workshop and industrial use.
• Zasilanie: Standard models are designed for 400 V, 3-faza, 50 Hz. 60 Hz and other voltage options are available.
• Thermal Motor Protection: Integrated to prevent motor burnout from overload or excessive use.

6. Łańcuch obciążeniowy

• Typ: Wysoka jakość, calibrated, alloy steel chain.
• Design: The famous Demag “Z” type or roller-link chain. This design ensures smooth operation and long life.
• Safety Factor: The chain exceeds all international safety standards with a high minimum breaking force.

7. Control and Safety Features

• Kontrola: Pendant control with 24V/42V safety extra-low voltage (SELV) for operator protection. Radio remote control is a common option.
• Górne/dolne wyłączniki krańcowe: Automatic switches with automatic reset to prevent over-hoisting.
• Mechanical Load Limiter: Protects the hoist and structure by slipping at a predetermined overload (NP., 125% of SWL).
• Phase Failure Protection: Prevents motor damage from incorrect phase sequence or phase loss.
• Zatrzymanie awaryjne: Standard on the pendant control.
• Motor Brake: A fail-safe, disc-type brake that engages automatically when power is cut.
• IP Rating: Typically IP55 (Dust protected and protected against water jets), making it suitable for harsh industrial environments.

8. Weight and Dimensions

• The DC series is renowned for its compact and lightweight design. Na przykład, a 500 kg capacity hoist can weigh as little as 28 kg, making it easier to integrate into existing structures without requiring massive support steelwork.

Why These Specifications Matter: The Competitive Edge

The technical specs of the Demag DC-hoist translate into direct benefits for the end-user:

• 1. Modularity: The specs aren’t fixed; they are a starting point for a customized solution.
• 2. Space-Saving: The compact dimensions maximize hook approach and lifting height in confined spaces.
• 3. Trwałość: High duty cycle ratings mean less downtime and a longer service life, even in tough conditions.
• 4. Safety by Design: Every specification, from the SELV control to the load limiter, is engineered for safe operation.
• 5. Energy Efficiency: Modern motors and efficient gearboxes ensure powerful performance with lower energy consumption.

The Demag DC-chain hoist isn’t just a collection of impressive technical specifications on a datasheet. It is a meticulously engineered system where every component—from the motor and chain to the smallest safety switch—is designed to work in perfect harmony. Its proven performance, flexibility, and unwavering reliability have made it a benchmark in the industry for a reason.

When specifying a lifting solution, understanding these details ensures you select equipment that delivers not just the required capacity, but also the safety, durability, and performance your operation demands.
