The Kingdom of Norway presents one of the most geologically challenging excavation and demolition landscapes in the world. Driven by intensive infrastructure expansions—such as the massive E39 Coastal Highway Route, extensive subsea tunneling works, and municipal renewals across mountainous terrains—the demands on hydraulic attachments and quick couplers are exceptionally unforgiving. Operating in deep fjords, hard granite terrains, and sub-zero Arctic conditions requires equipment designed for extreme performance.
Additionally, Norway is the global pioneer in fossil-free and zero-emission construction sites. The rapid adoption of large-scale electric excavators means that hydraulic quick couplers must minimize pressure drop to conserve battery power. The optimization of internal hydraulic manifold designs inside high-pressure tilt couplers plays a decisive role in increasing the runtime of electric excavators by up to 15%.
In Norway, worker safety is regulated strictly under Helse, miljø og sikkerhet (HMS) frameworks. Safety requirements for quick couplers are governed by the harmonized European Standard EN 474-1, which enforces stringent mechanical lock systems to prevent the accidental release of heavy buckets or demolition shears.
Yantai Huida uses high-precision horizontal and vertical CNC machining centers coupled with fully automated robotic welding tracks to ensure consistent mechanical tolerance, perfect pin-to-pin alignment, and zero structural defect rates.
Our raw material procurement runs on a strict trackability program. Every batch of low-temperature casting alloy or heavy steel plate undergoes strict ultrasonic testing, tensile force verification, and chemical composition analysis.
With our massive material inventory and streamlined modern production planning, we guarantee quick coupler production times that are up to 40% shorter than average EU domestic manufacturers, ensuring agile project delivery.
Global procurement specialists are shifting strategies away from fragmented local supply chains towards highly reliable, smart manufacturing plants in China. By combining cutting-edge industrial capacity with rigorous engineering standards, Yantai Huida provides structural attachments that achieve identical mechanical performance to premium local Nordic brands but at a significantly optimized cost structure. This enables rental companies and large infrastructure contractors across Oslo, Bergen, and Trondheim to maximize their return on investment (ROI) without sacrificing mechanical durability or site safety.
Initially established in December 2016 and renamed on March 25, 2019, with a registered capital of 20 million yuan, Yantai Huida Intelligent Equipment Co., Ltd. is a leading professional manufacturer dedicated to the research, development, production, and sales of high-performance excavator accessories, scrap steel processing equipment, and environmental engineering tools.
Over the years, the company has accumulated nearly 40 product invention patents. Our comprehensive production lineup includes heavy-duty hydraulic quick couplers, Eagle hydraulic shears, Double Cylinder Steel Shears, Hydraulic Car Scrap Shears, heavy crushers, grabs, lifting electromagnets, rippers, and hydraulic breakers.
Our core business philosophy is: "Putting customers at the center and providing attentive service". Guided by our values of "innovation and efficiency, striving for excellence, and service first", we strive to build long-term relationships with global distributors, equipment hire corporations, and engineering contractors in the Norway market and beyond.
"Putting customers at the center and providing attentive service is our eternal and unchanging purpose on the road of development."
When dealing with problems in work, we are indomitable and steadfast like a rock. We continuously break through and innovate in professional technology, introducing 6 highly skilled R&D personnel with advanced technical engineering capabilities, and employing nearly 50 professional processing technicians.
Our technical team focuses intensely on materials engineering and hydraulic optimization. Quick couplers used in the Norway market must face geological conditions dominated by high-density igneous rock like granite and basalt. When excavating or hammering in these terrains, the level of vibration back-shocks delivered to the quick coupler and the excavator's boom is extremely high.
To withstand this continuous mechanical fatigue, our R&D department has designed advanced internal dampening systems and high-strength locking mechanisms. We pay close attention to supplier management and establish rigorous plans to ensure quality at the source. Long-term partners provide certified high-grade structural alloys, ensuring that our products have the rugged reliability needed to tackle Norway's most demanding projects.

OEM Partners, heavy machinery agents, rental companies, demolition contractors, and specialized end-use construction providers.
We provide expert pre-sales product consultations, comprehensive training on usage, control software system upgrades, replacement components at cost price, and custom packaging/logistics planning.
We guarantee a direct technical response within 24 hours, enforce strict business information confidentiality, and provide a 6-month free replacement program for any manufacturing issues on accessories.
In Norway, quick couplers must comply with the harmonized European standard EN 474-1 and local HMS (Helse, miljø og sikkerhet) guidelines. This requires active mechanical double-locking systems, such as positive pin locks, that prevent accidental detachment even during absolute hydraulic pressure drops. Visual locks or electronic pressure sensors are also highly recommended for site operators.
Symmetrical quick couplers (S-type) are extremely popular in Norway and the wider Nordic region due to their low weight, low build height, and standardized connection dimension. This compact footprint is essential when pairing attachments with high-performance tiltrotators, preserving excavating breakout forces and minimizing fuel consumption.
Sub-zero temperatures decrease the impact toughness of structural carbon steels, making them vulnerable to sudden brittle fractures under heavy impact. Yantai Huida resolves this by utilizing certified low-temperature structural alloy steels and specialized heat-treatment casting methodologies, retaining excellent yield strength and elasticity down to -30°C.
Yes. Backed by advanced Factory 4.0 production plants and 6 senior R&D engineering experts, Yantai Huida specializes in customized OEM/ODM fabrication. We can modify pin dimensions, adjust locking offsets, optimize hydraulic configurations, and integrate third-party hydraulic systems to fit local requirements perfectly.
