Yantai Huida Intelligent Equipment Co., Ltd. was initially established in December 2016 and was renamed on March 25, 2019 with a registered capital of 20 million yuan. We are a professional enterprise dedicated to the research, development, production, and sales of scrap steel processing machinery, automobile recycling equipment, renewable resource utilization units, environmental protection and energy-saving systems, and premium heavy-duty excavator accessories.
Through aggressive R&D, our enterprise has obtained nearly 40 product invention patents, certifying our technological excellence in hydraulic and mechanical design. At present, our core catalog spans high-end machinery and excavator attachments, including Eagle Hydraulic Shears, Double Cylinder Steel Shears, Hydraulic Car Scrap Shears, Heavy Crushers, Grabs, Quick Couplers, Lifting Electromagnets, Rippers, and Breakers.
Every piece of machinery that leaves our line undergoes a rigorous quality control framework, tracking processes from the early sourcing of high-strength structural steels and certified hydraulic components to multi-stage simulation testing under high loads. We are fully ISO9001 Quality Management System certified, reflecting our unwavering commitment to the strict standards expected by international civil engineering and scrap processing companies.
Understanding structural soil dynamics, centrifugal forces, and vibration metrics is critical for B2B procurement professionals. Below, we break down the mechanical parameters that define professional-grade compactor performance.
Vibrations per Minute (VPM) determine the rate at which the eccentric mass rotates inside the exciter housing. Small vibratory plates operating at higher frequencies (4,000 to 5,500 VPM) are optimized for cohesive soils and fine granular materials. High frequency reduces frictional resistance between aggregate particles, enabling rapid air expulsion and reaching maximum dry density with fewer passes.
Generated by the rotational eccentric weight system, centrifugal force is the kinetic output directed straight into the soil. For small compactors mounted on mini excavators (typically 1.5 to 8 tons), an output force of 15 kN to 35 kN is optimal. This dynamic pressure wave penetrates deeply without fracturing structured stone sub-bases, ensuring uniform, non-yielding layers.
Standard steel wear limits the lifespan of general compactors. OEM heavy-duty compactors require baseplates cast from high-tensile, wear-resistant steel (such as Hardox or high-carbon alloys). The design of a tapered or curved edge profile prevents the plate from gouging compacted soil, which is vital in asphalt sealing or tight utility trench work.
| Excavator Weight Class (Tons) | Optimal Compactor Model VPM | Centrifugal Force Output (kN) | Baseplate Dimensions (mm) | Hydraulic Working Pressure (Bar) | Typical Compaction Depth (mm) |
|---|---|---|---|---|---|
| 1.5 - 3.5 Tons (Mini) | 4,200 - 4,800 VPM | 15 - 20 kN | 600 x 400 mm | 90 - 120 Bar | 200 - 300 mm |
| 4.0 - 6.0 Tons (Midi) | 4,500 - 5,000 VPM | 22 - 28 kN | 750 x 500 mm | 110 - 140 Bar | 300 - 450 mm |
| 7.0 - 10.0 Tons (Utility) | 4,800 - 5,500 VPM | 30 - 38 kN | 900 x 600 mm | 130 - 160 Bar | 400 - 600 mm |
Take an inside look at our manufacturing infrastructure, CNC testing cells, raw material processing center, and quality-checking stations in Shandong, China.
The global civil engineering and machinery attachment market is experiencing major cost consolidation. International dealers, construction companies, and rental fleets are shifting their procurement strategies toward specialized Chinese manufacturing hubs like Yantai. Let’s evaluate the industrial factors behind this shift:
Chinese steel mills produce world-class high-tensile steels. By leveraging proximity to local supply chains, our factory utilizes high-efficiency induction tempering, giving baseplates and exciter housings unmatched crack resistance under high VPM conditions.
Modern excavators operate on complex high-flow systems. Our hydraulic motors (sourced from reputable local and global suppliers) are customized with dual-direction pressure relief valves, preventing pressure spikes from damaging the carrier machine's hydraulic circuit.
Whether you require specific pin dimensions to match your hydraulic quick coupler systems, custom corporate paint schemes, or private-label branding, our engineering team handles customization from CAD design to final assembly.
Every product undergoes dynamic loading simulations, pressure-retention testing, and visual welds inspection under strict ISO9001 protocols. This ensures your components perform reliably right out of the crate, minimizing warranty claims for distributors.
Optimized production flows, in-house tooling, and highly skilled machining lines significantly lower manufacturing costs without compromising quality, passing massive price advantages directly to international buyers.
We are not just a supplier; we are a long-term engineering partner. We secure raw material availability and design components ahead of industry demand, ensuring constant part availability for our dealers worldwide.
"Never give up, never give up" is our core team spirit. When dealing with complex mechanical problems, we are indomitable and steadfast like a rock. We continuously break through and innovate in professional technology, introducing 6 core R&D and design specialists with high-end skills and deep professional knowledge, and maintaining nearly 50 professional processing technicians.
We focus heavily on team management and business management, establishing a comprehensive system for personnel management, quality management, safety management, and environmental protection, effectively ensuring safe production and laying a solid foundation for timely, high-quality deliveries.
In addition, we prioritize supplier management and establish clear criteria to ensure product quality at the source. We have established long-term and stable cooperative relationships with major well-known raw material and supporting component companies to ensure absolute reliability and project schedule adherence.
Circuit Technology Center Capabilities:
In addition to high-strength mechanical castings and hydraulic assemblies, our engineering capabilities extend to advanced electronics and control integration. We have the capability to design and manufacture 1 to 24 layered printed circuit boards (PCBs) to power intelligent attachment monitoring systems.
Our maximum board size for multilayer PCBs is 16” x 26”, and the standard manufacturing turnaround time is fully tailored to the complexity and quantity of the boards needed. This enables us to integrate electronic sensors, vibration frequency trackers, and automated diagnostic controls directly into advanced hydraulic attachment series.

Excavator-mounted small vibratory plate compactors are versatile tools across several sectors. Because they convert an excavator’s hydraulic power into vertical compaction force, they provide unmatched flexibility in tight spaces. Let’s evaluate the primary localized applications:
Compacting soil around gas lines, water pipes, and electrical conduits requires precision. Conventional walk-behind rollers are unsafe for workers in deep trenches. An excavator-mounted compactor plate allows operators to compress backfill materials directly from the safety of the cab, preventing cave-ins and achieving perfect density.
Compacting steep highway embankments, bridge abutments, and canal slopes is difficult for standard rollers. Our compactors reach steep inclines easily when paired with long-reach booms. The dynamic vibration seals the slope, preventing future soil erosion.
Getting close to concrete footings, foundation walls, and curb columns is a challenge for large compaction equipment. Small compactor plates operate right up against structures. The rubber vibration-damping mounts isolate the excavator boom from damaging vibration feedback.
