1. Fitur & Manfaat Utama

• Genuine OEM-spec swing motor assembly – OEM part number 452-6209 (juga dirujuk sebagai PCR-4B-20A). Direkayasa sesuai spesifikasi peralatan asli Caterpillar untuk CAT 305.5E2, 306E2, dan ekskavator mini kelas 5–6 ton yang kompatibel. Ini adalah unit baru dengan spesifikasi pabrik – bukan hasil remanufaktur, bukan pengganti generik.

• Kualitas Produk – Hongtengda Parts – The swing motor is the heart of the upper structure rotation system, responsible for driving the rotational movement of the cab, boom, arm, and bucket. It converts hydraulic power into controlled rotational motion, enabling the excavator to swing horizontally for efficient digging and material placement. When this motor fails, the machine cannot position itself for productive work.

• Direct replacement for CAT 305.5E2 and 306E2 – Specifically designed for Caterpillar 305.5E2, 306E2, and compatible models including 305E, 305E2 CR, 305.5D, and 306. Mounting flange, shaft interface, and hydraulic port configurations match the original Caterpillar specifications exactly – no modifications, no adapters.

• PCR-4B-20A platform – NACHI’s proven mini excavator swing technology – The PCR-4B-20A is part of NACHI’s renowned PCR series of axial piston swing motors. PCR series motors integrate an axial piston hydraulic motor with a planetary gearbox and braking mechanism in a compact assembly, providing smooth, reliable rotation for 5–6 ton class machines.

• High torque output for 5–6 ton class work – Delivers the torque and rotational power needed for precise slewing operations even under full bucket loads. The swing motor works in tandem with the swing drive gearbox to rotate the upper structure smoothly. The assembly weighs approximately 60 kg (132 lb) with dimensions of 45 × 35 × 35 cm.

• Integrated parking brake for slope safety – The swing motor features a built‑in spring-applied, hydraulically-released disc parking brake. When the hydraulic control console is raised or the engine is stopped, the brake engages automatically, holding the upper structure securely on slopes. When a swing operation is started, the brake releases instantly for immediate response.

• Relief and makeup valves for circuit protection – Integrated relief valves protect the swing motor against pressure spikes during sudden stops or overloads. Makeup (anti‑cavitation) valves prevent vacuum damage during rapid deceleration. Together, these valves ensure smooth, jerk‑free slewing and extend motor life.

• Konstruksi kokoh untuk kondisi yang menuntut. – Key components are crafted from high-quality materials with specialized treatments for excellent wear and corrosion resistance. The rational structural design simplifies maintenance and extends service life. Operates reliably in harsh conditions including dust, moisture, and temperature extremes.

• Verifikasi visual pra-pengiriman – Sebelum pengemasan, kami akan mengirimkan kepada Anda foto-foto terperinci beresolusi tinggi dari unit aslinya (flensa pemasangan, alur gigi, ulir port, bagian cor, serta kondisi keseluruhan). Anda harus menyetujui pengiriman tersebut – kami tidak pernah mengirimkan barang tanpa persetujuan Anda terlebih dahulu.

• Pengiriman cepat – Waktu tunggu 5–8 hari kerja dari gudang Guangzhou kami. Kapasitas pasokan bulanan 300 unit, tersedia untuk pesanan satuan atau grosir.

2. Aplikasi

The genuine CAT 452-6209 swing motor assembly is the power source for the slewing system on CAT 305.5E2 and 306E2 mini excavators used across a wide range of job sites:

• Konstruksi perkotaan & utilitas – Road building, sidewalk repairs, house demolition, water and gas line trenching, and fibre‑optic cable installation. The swing motor’s precise rotational control and smooth start‑stop characteristics are essential for working near existing structures without overswinging or causing damage.

• Pengembangan perumahan & komersial – Foundation digging, basement excavation, retaining walls, grading, and site preparation. The smooth rotation and instant response enable operators to place materials accurately and work efficiently in confined residential spaces.

• Rural development & agriculture – Agricultural irrigation, land leveling, rural road construction, drainage ditch cleaning, and pond maintenance. The swing motor’s robust construction and sealed design withstand dirt, moisture, and debris common in agricultural environments.

• Landscaping & pool excavation – Pool digs, retaining walls, grading, and drainage work. The smooth, jerk‑free slewing provided by the relief and makeup valves minimises disturbance to nearby homes, while the integrated parking brake holds the upper structure securely on slopes.

• Armada sewa peralatan – Mini excavators are the most frequently rented machines. A genuine new swing motor provides predictable service life and eliminates the gamble of remanufactured or used units – avoiding costly mid‑rental failures, towing bills, and customer complaints. The swing motor is a high‑wear component on rental machines due to constant rotation and varying operator habits.

• Pembersihan hutan & vegetasi – Steep slopes, fallen timber, and uneven terrain demand reliable swing performance. The swing motor’s robust construction and sealed bearings withstand the dirt, moisture, and debris common in forestry applications.

We do not sell “compatible” substitutes or generic replacements – you receive a motor that matches the original in every measurable dimension.

Rigorous pre‑shipment inspection – Each swing motor undergoes a thorough visual inspection and functional verification before it is released for shipment. We check:

• Mounting flange flatness and bolt hole alignment

• Hydraulic port thread integrity and seal surfaces

• Shaft spline condition and dimensional accuracy

• Overall casting integrity and paint finish

High-quality materials and manufacturing – Key components are crafted from high-quality materials with specialized treatments for excellent wear and corrosion resistance. The rational structural design simplifies maintenance and extends service life. Advanced manufacturing processes ensure stable, high-performance operation even under harsh conditions.
