Working Principle

Hydropower shaft gantry cranes use a vertical lifting system for deep shaft construction, connecting ground handling with controlled lifting inside the shaft.

1. Rail or foundation installation: Rails or a fixed base are installed around the shaft opening to support crane operation.

2. Gantry structure setup: The gantry frame is assembled across the shaft and connected to the hoisting system.

3. Hoisting system activation: Winches and wire ropes are engaged to provide controlled vertical lifting power.

4. Load preparation and lifting: Materials or equipment are secured to lifting hooks and raised or lowered into the shaft.

5. Vertical movement in the shaft: The load is guided along a controlled vertical path inside the shaft opening.

6. Placement and unloading:The load is positioned at the required level and released for construction use.

7. Return for next cycle: The system returns to the starting position to prepare for the next lifting operation.

The process follows a repeated cycle from setup to lifting and unloading, supporting continuous vertical transport in hydropower shaft construction. Learn more about how the equipment works: How Does a Vertical Shaft Gantry Crane Work?

Overhead Slab Crane with Clamp Parts

Bridge Girder
High-strength steel structure main body, bearing the entire machine load, ensuring stable operation under heavy load and high-temperature conditions.
Hoisting & Travelling Mechanism
Includes hoisting mechanism, main trolley and auxiliary trolley mechanisms, enabling smooth lifting and precise handling of slabs.
Slab Clamp Device
Mechanical or hydraulic clamps, providing reliable gripping and preventing slippage, suitable for slabs of different sizes and temperatures.
Electrical & Control System
Variable frequency speed control and PLC control, supporting automatic/semi-automatic operation, improving operational efficiency and safety.
Safety Devices
Multiple protections including overload protection, limit switches, anti-slip devices, and emergency braking, ensuring safe continuous production.

Working Principle

The coordinated operation of the bridge structure and the clamp lifting device enables the safe clamping, lifting, and transportation of steel slabs. During operation, the trolley moves above the steel slab, and the clamps open and align with the slab under the drive of the lifting mechanism or hydraulic system. After the lifting mechanism is activated, the clamps automatically grip the steel slab, forming a reliable self-locking or hydraulic clamping force. Then, the crane, through the bridge and trolley running mechanisms, smoothly transports the steel slab longitudinally and laterally to the designated position. Throughout the entire process, frequency conversion control and the PLC system precisely regulate the lifting and traveling speeds, and continuously monitor the clamping status and load conditions, ensuring that the steel slab does not slip under high-temperature or heavy-load conditions, thus guaranteeing safe and efficient continuous handling operations.

Working Principle

The YZ-type casting ladle crane primarily operates through the coordinated action of two independent hoisting mechanisms: the main hoist drives the gantry hook beam, responsible for safely lifting ladles filled with molten metal; the auxiliary hoist is used for pouring molten steel, assisting in ladle rotation, or handling other auxiliary equipment. Its working principle can be summarized as follows:

The YZ Ladle Handling Crane employs electric drives for its main and auxiliary travel mechanisms and hoisting systems. Utilizing the gantry hook of the main hoist, it lifts ladles containing molten steel. Coordinated with the auxiliary hoist, it facilitates ladle transfer or casting operations. The entire unit incorporates high-temperature resistant design, dual braking systems, and redundant wire rope configurations to ensure safe and stable liquid metal transfer within extreme environments characterized by high temperatures and heavy dust.

 

Common Lifting Attachments

The lifting device is the component that directly contacts or approaches the molten metal ladle, requiring exceptional structural strength and thermal insulation capabilities. As it operates continuously within the thermal radiation range of liquid metal exceeding 1500°C while enduring static and dynamic loads of hundreds of tons, the YZ crane primarily employs the following lifting devices tailored to diverse process requirements:

Standard Gantry Hook

Featuring a laminated high-toughness structure and thermally insulated reinforced beam design, it maintains load-bearing capacity even with localized damage. This makes it the safest and most widely used lifting device for standard ladle handling.

Features

YZ Steel Mill Ladle Cranes are specifically engineered for molten steel handling in steelmaking and casting processes. They deliver safe, stable, and high-precision operation under high-temperature, heavy-load, and continuous-duty conditions. Featuring metallurgical-grade structural reinforcement, specialized hoisting systems, and multiple safety protection configurations, these cranes meet critical production demands including ladle transfer, positioning, pouring, and auxiliary operations.

Application

YZ Steel Mill Ladle Cranes are primarily used for molten steel handling and process integration in steel mills and large foundries, covering the entire process from tapping, refining to pouring. They ensure safe transfer and precise positioning of ladles under high-temperature, heavy-load, and continuous operation conditions, serving as critical equipment for maintaining continuous molten steel production and operational safety.

Converter/Electric Arc Furnace Tapping Area: Designed to carry and transfer high-temperature ladles, featuring high load capacity and impact-resistant structures.

Steel Refining Stations (LF, RH, etc.): Enables frequent short-distance movement and precise positioning of ladles with smooth operation, effectively minimizing molten steel agitation.

Continuous Casting Machine Pouring Area: Used for ladle positioning and pouring operations, with optional rotation or weighing functions to enhance pouring precision and production efficiency.

Internal Transport Corridors in Foundry Workshops: Handle continuous molten steel transfer between multiple workstations, adapted for high-temperature environments and prolonged operation to ensure stable production rhythms.
