Overview of ZOKECRANE LDY Metallurgical Single Girder Overhead Crane
Manufactured by Henan Zoke Crane Co., Ltd., the LDY series metallurgical single girder overhead crane (often paired with YH/YDH metallurgical electric wire rope hoists) adheres to strict industrial safety standards (such as JB/T 1306 and metallurgical crane specifications). Built with thermal insulation barriers, H-class high-temperature insulated motors, double brakes on hoisting mechanisms, and heat-resistant steel wire ropes, ZOKECRANE provides reliable, durable, and highly secure lifting equipment for global metal processing industries.

Core Product Advantages & Safety Features
- Dual Braking Safety System: The main hoisting mechanism is equipped with double brakes (operational brake + safety brake/load brake) to prevent accidental load drop in high-temperature liquid metal handling.
- Thermal Radiation Shielding: Thermal protection barriers and heat-insulating plates are fitted under the main beam and electric hoist frame to block direct heat radiation from molten metal pools.
- High-Temperature Resistant Components: Utilizes steel-core wire ropes designed for high temperatures, flame-resistant cables, and H-class insulated motors specifically rated for foundry duty cycles.
- Over-Speed & Double Limiter Protection: Features double lifting limit switches (position limit + upper switch limit) and over-speed safety protection on hoisting machinery.
Industrial Applications of LDY Metallurgical Cranes
ZOKECRANE LDY metallurgical single girder overhead cranes are vital assets in metal processing and heavy thermal industries across international markets:
1. Foundries & Steel Casting Plants
Used for lifting and transferring molten iron or steel ladles, pouring liquid metal into molds, and handling hot casting boxes under severe heat.
2. Heat Treatment & Forging Workshops
Ideal for moving red-hot metal billets, forgings, and dies in and out of heat treatment furnaces, quenching tanks, and forging presses.
3. Non-Ferrous Metal Smelting (Aluminum, Copper, Zinc)
Ensures stable overhead handling of liquid aluminum crucibles, copper anode plates, and molten alloy ladles in non-ferrous smelters.
4. Metallurgy Auxiliary & Scrap Handling
Deployed for lifting foundry additives, scrap metal charging buckets, and hot slag pots in auxiliary melt-shop bays.
Frequently Asked Questions (Product FAQs)
What makes an LDY crane different from a standard LD single girder crane?
Unlike standard LD cranes, the LDY metallurgical crane is specifically built for hot metal environments. It features H-class heat insulation motors, double hoisting brakes, heat-resistant steel-core wire ropes, bottom thermal shielding plates, special fire-resistant wiring, and a dedicated YH-series metallurgical hoist.
Why is a double brake required on the hoisting mechanism of an LDY metallurgical crane?
Safety is critical when handling liquid or molten metal. In the event of a primary brake mechanism failure, the secondary mechanical/safety brake immediately engages to hold the load, preventing catastrophic spills and protecting foundry personnel.
What ambient temperature range can the LDY metallurgical crane withstand?
ZOKECRANE LDY cranes operate reliably in ambient room temperatures up to +60°C. With bottom thermal radiation shielding, the structure and electrical systems can safely tolerate radiant heat from molten steel at temperatures exceeding 1,000°C.
Can LDY metallurgical single girder cranes be customized for low-headroom workshops?
Yes. We offer low-headroom metallurgical trolley designs that optimize effective hook lift height in facilities with restricted vertical clearance above furnace platforms.
Export & Logistics FAQs for International Buyers
Which international markets has ZOKECRANE supplied metallurgical cranes to?
ZOKECRANE has delivered metallurgical and industrial overhead cranes to customers in Russia, Uzbekistan, the Philippines, Bangladesh, Australia, Qatar, Tanzania, Singapore, Saudi Arabia, Brazil, Nigeria, and numerous other steelmaking regions globally.
How are LDY metallurgical cranes packaged for international sea transport?
Main girder beams receive protective anti-corrosion coatings and structural wrapping. Electric hoists, control panels, double brakes, and motor assemblies are wrapped in moisture-proof plastic sealings and packed in export-standard fumigated wooden cases to prevent salt-air corrosion and mechanical damage during shipping.
What certifications accompany ZOKECRANE metallurgical lifting equipment?
Every ZOKECRANE LDY metallurgical crane is supplied with full quality assurance documentation, including ISO 9001 compliance, European CE certificates, SGS third-party inspection reports, motor/hoist test certificates, and non-destructive weld testing (NDT) documentation.
What delivery terms and manufacturing lead times do you provide?
We support standard commercial delivery terms including FOB, CIF, CFR, DDU, and DDP. Depending on single-girder span length, duty rating, and custom electrical specifications, standard manufacturing lead times range from 20 to 30 business days.
How does ZOKECRANE assist overseas clients with installation and commissioning?
We provide comprehensive technical documentation, detailed electrical wiring schematics, structural foundation layouts, and 3D installation guides. Our engineering team provides 24/7 remote video technical assistance or can dispatch experienced engineers for on-site installation oversight, load testing, and operator training upon customer request.
