自由容器

Engineered Around
Your Powerhouse Lifting Plan

Hydropower station overhead cranes are configured according to the heaviest component, maintenance route, lifting height, hook coverage, positioning requirement and plant layout.

Generator Rotor Handling

Installation, removal and major maintenance lifts

Turbine Runner Handling

Controlled lifting of turbine

rotating components

Stator & Generator

Components

Assembly and maintenance

of heavy electrical equipment

Main Shaft & Bearing

Components

Handling shafts, bearings and related assemblies

Main Inlet Valve

Maintenance

Removal and positioning of

heavy valve components

Major Overhaul Lifts

Planned outage and long-

term maintenance operations

Rated capacity alone is not enough for crane

selection. The heaviest component, lifting

device, hook block and complete critical-lift

route must also be confirmed.

Frequently Asked
Questions
—

What is a hydropower station overhead crane?

It is a powerhouse bridge crane engineered for

installing，maintaining and removing turbine-

generator components and other heavy plant

equipment.

Is it the same as a turbine hall crane?

In most powerhouse applications, the terms are closely

related. Turbine hall crane emphasizes the installation

location.

Is it the same as an intake gate crane?

No. A powerhouse crane handles turbine-generator

equipment inside the plant, while gate cranes operate

around waterways and gates.

How is crane capacity selected?

Capacity must include the heaviest component, lifting

beam, hook block, rigging and every suspended item.

Can the crane lift a generator rotor in one piece?

Yes, when the rotor weight, dimensions, lifting device，

hook coverage and complete lifting route are included

in the design.

Can an existing hydropower crane be modernized?

Yes. Drives, brakes, controls and monitoring functions

can be evaluated, subject to structural and runway

condition.

Initial proposal inputs: heaviest component，component drawing, powerhouse span, lifting height and maintenance plan.
