Seattle, known as a global hub for aerospace, maritime logistics, and high-tech manufacturing, demands the highest standards in lifting and material handling equipment. As leading Chain Block Accessories Manufacturers & Suppliers in Seattle, we understand that the local industry—from the bustling Port of Seattle to the massive assembly lines of Everett—relies on precision-engineered components. Chain blocks and their accessories are the backbone of construction, shipyard maintenance, and warehouse automation throughout the Pacific Northwest.
Our accessories are designed to withstand the unique environmental challenges of the Seattle area, including high humidity and coastal salt-air exposure, which can lead to rapid corrosion in inferior products. By utilizing advanced metallurgy and AI-driven quality control, we provide local businesses with chains, hooks, and slide blocks that ensure safety and longevity in demanding applications.

The industry for chain block accessories is undergoing a digital transformation. In Seattle’s tech-forward environment, "Smart Lifting" is becoming the norm. We are integrating predictive maintenance data into our manufacturing process, ensuring that every escalator drive chain or compression chain we supply meets the specific stress-load requirements of modern infrastructure.
Modern trends include the use of lightweight yet ultra-high-tensile alloys and the application of IoT sensors in lifting blocks to monitor wear and tear in real-time. Our commitment to innovation aligns with Seattle’s vision of a sustainable and technologically advanced industrial future.
For over a decade, Foshan Dalong Chain Equipments Sales Co., Ltd. has upheld a development policy characterized by pragmatism, self-reliance, and innovation. Specializing in the sales of major brand elevator components, we offer an integrated approach that encompasses sales, manufacturing (Custom manufacturing of parts for elevators and escalators that are non-standard, discontinued, or of older models) and engineering technical consulting.




Seattle’s terminals require heavy-duty chain blocks for cargo securing and ship maintenance. Our corrosion-resistant accessories are ideal for the salty Puget Sound environment.
With the rise of vertical urbanism in Downtown Seattle, high-speed elevators and escalators in skyscrapers like the Columbia Center require our precision-engineered drive chains and slide blocks for 24/7 operation.
Precise lifting is critical in aircraft assembly. Our accessories provide the micro-adjustment capabilities needed for delicate aerospace components.
