LDY type metallurgical electric single-girder crane

The LDY type metallurgical electric single-girder crane is a lifting device specially designed for metallurgy and foundry applications. Its core function is to safely and efficiently complete the lifting and transportation of molten metal. With a lifting capacity ≤ 10t, it features special heat insulation treatment on the bottom of the main girder, and is suitable for working environments with temperatures ranging from -20°C to 60°C.
Specifications
  • Lifting capacity: 1-32t
  • Span: 3-35m
  • Lifting height: 9, 15, 21, 27m
  • Working environment: -20~60℃
Introduction

The LDY metallurgical electric single-girder crane is a lifting equipment specially designed for metallurgical and foundry applications. Its core function is to safely and efficiently complete the lifting and transportation of molten metal. Lifting capacity ≤10t. The bottom of the main girder features special heat insulation treatment. The working environment temperature is -20~60℃.

It is typically used in conjunction with a metallurgical electric hoist, ensuring reliability and safety in harsh industrial environments such as high temperature and high humidity.

Structural Composition

The single-girder crane mainly consists of a main girder, end carriages, an electric hoist, a travel mechanism, and an electrical control system. The characteristics of each component are as follows:

  • Main Girder: Adopts a box-type or I-beam welded structure, lightweight design, strong load-bearing capacity.
  • End Carriages: Connect the main girder to the track, equipped with high-strength wheels and buffer devices for smooth crane movement.
  • Electric Hoist: Commonly uses a YH metallurgical electric hoist, featuring multiple protection functions such as dual brakes, dual limit switches, and heat shields.
  • Travel Mechanism: Composed of a motor, reducer, and wheels, it drives the crane along the track and supports variable frequency speed regulation.
  • Electrical Control System: Includes a control cabinet, remote controller, or operator’s cab, enabling safe operation and automation functions (such as limit protection).

Advantages & Features

Specialized Design & Safety Treatment
Specifically for metallurgical environments, the bottom of the crane’s main girder features special heat insulation treatment. This is a key design that distinguishes it from普通 cranes, effectively应对 high-temperature radiation.
Strong Environmental Adaptability
The equipment is designed for a working environment temperature of -20℃ to 60℃. At a temperature of 40℃, the ambient relative humidity does not exceed 50%, ensuring its stability in specific high-temperature, high-humidity environments.
Compliance & Standards
The design and manufacturing of the crane comply with national standard requirements, meeting the stringent standards of metallurgical working conditions.
Flexible Operation Modes
Provides two operation modes: floor operation and cabin operation. The operator’s cab can be open or enclosed, and can be customized and installed according to actual working condition requirements, offering great flexibility.

Specifications

Applications

  • Metal Smelting & Foundry: Used in metal smelting and foundry workshops for lifting molten metals such as molten steel and molten iron.
  • Hot Solid Metal Handling: Used for lifting hot solid metals, such as metal billets or workpieces just after rolling or forging.
  • Molten Non-Metallic Materials: Can also be used for lifting molten non-metallic materials.
