nnnn

Dongfang (Guangzhou) Heavy Machinery Co. Ltd

nnnn

(DFHM) was founded in 2004 as a world-class

nnnn

manufacturer of large and complex components for

nnnn

nuclear power generation and petrochemical plants.

nnnn

The parent company, Dongfang Electric Corpora-

nnnn

tion (DEC), is listed by the State Council, Assets

nnnn

Supervision and Administration Committee as

nnnn

one of the 53 key state-owned enterprises critical

nnnn

to China's national security and economy. China

nnnn

is emphasizing nuclear power generation as one of

nnnn

the ways to reduce pollution from traditional coal-

nnnn

fired power plants and to meet the country's rapidly

nnnn

growing energy demands.

nnnn

The construction of the DFHM manufacturing

nnnn

facility was an important project for China, signal-

nnnn

ing to the world its new heavy industrial capabilities.

nnnn

China United Engineering Corporation designed

nnnn

the facility and was awarded the China Civil Engi-

nnnn

neering Society Zhan Tianyou Award, which is the

nnnn

country's highest engineering award. This was the

nnnn

first time the award was given for an industrial

nnnn

project and shares honors with other world-renowned

nnnn

Chinese projects such as the National Stadium

nnnn

(Bird's Nest), National Swimming Center (Water

nnnn

Cube) and Beijing International Airport Terminal 3.

nnnn

The first phase of the manufacturing plant required

nnnn

a massive door that would allow a 1 400 ton over-

nnnn

head crane to exit the building to unload large rough

nnnn

materials and load finished components onto trans-

nnnn

port ships. After reviewing all their options, the de-

nnnn

sign team chose Megadoor to supply the crane door.

nnnn

Critical Issues:

nnnn

• Reliability - The crane door is opened regularly

nnnn

and is a critical part of the production process.

nnnn

If the crane door is inoperable, the negative fi-

nnnn

nancial impact from production or shipping de-

nnnn

lays will be significant.

nnnn

• Cost of ownership - Minimize maintenance

nnnn

costs associated with regular usage in a corrosive

nnnn

marine environment.

nnnn

• Building loads - The loads imposed by the

nnnn

crane door on the building structure can add sig-

nnnn

nificant construction costs.

nnnn

• Support- Local support for service, parts and

nnnn

preventative maintenance.

nnnn

Megadoor Provided:

nnnn

• Overhead crane door design and facilitated the

nnnn

structural integration of the door system with

nnnn

the building.

nnnn

• (1) 3-part overhead crane door system. Center

nnnn

door dimensions are 28 m clear width x 32.8 m

nnnn

clear height (92'x 108'). When the crane rail

nnnn

doors and mullions are opened, they allow a

nnnn

35.5 m (116') wide crane to move in and out of

nnnn

the building.

nnnn

• Project coordination, installation, after-sales

nnnn

support and quarterly preventative maintenance

nnnn

provided by Crawford China's local Guangzhou

nnnn

office.

nnnn

Benefits:

nnnn

• Quality and reliability - Megadoor is the world

nnnn

leader in supplying large, complex door systems

nnnn

for heavy industry. Over the last 25 years,

nnnn

Megadoor has earned a reputation for quality

nnnn

products, performing reliably, in the world's

nnnn

harshest environments. Managers in steel mills,

nnnn

shipyards, military bases and manufacturing

nnnn

plants across the globe count on Megadoor over-

nnnn

head crane doors in their production process.

nnnn

• Cost of ownership - The Megadoor is engineered

nnnn

for high-cycle usage by minimizing the amount

nnnn

of moving parts and wear items in the door sys-

nnnn

tem. Additionally, the majority of door com-

nnnn

ponents are manufactured out aluminum and

nnnn

PVC-coated polyester fabric, which eliminates

nnnn

corrosion costs and painting, making Megadoor

nnnn

the clear choice for marine environments.

nnnn

• Building loads - The strong but lightweight

nnnn

aluminum and PVC-coated polyester fabric con-

nnnn

struction minimizes the weight of the Megadoor

nnnn

system and loads imposed on a building struc-

nnnn

ture. Other crane door systems manufactured

nnnn

out of steel cost substantially more to support.

nnnn

• Support - Megadoor is a part of Cardo Entrance

nnnn

Solutions, which also includes the globally recog-

nnnn

nized Crawford brand for door and docking so-

nnnn

lutions. We have built the most extensive service

nnnn

organization in the industry with over 50 skilled

nnnn

Crawford service engineers in China who are ready

nnnn

to provide scheduled preventive maintenance as

nnnn

well as urgent repairs. In China, we have sev-

nnnn

en strategically located offices, including our

nnnn

Guangzhou office that supports DFHM.

nnnn
