# Zoomlion ZR280 1031400162 / 1031400319 Track Sprocket Wheel Assembly: Direct from CQCTRACK Factory for Heavy-Duty Drilling Rigs

**Meta Description:** Source the OEM-grade track sprocket wheel assembly (P/N 1031400162 / 1031400319) for your Zoomlion ZR280 rotary drilling rig from CQCTRACK. A specialist manufacturer delivering forged toughness, tooth-profile precision, and global mine‑site logistics.

## The Drivetrain Anchor of the Zoomlion ZR280 Piling Rig
The Zoomlion ZR280 is an 80‑tonne class rotary drilling rig built for deep pile foundations on bridges, viaducts, wind turbines, and high‑rise structures. Unlike a standard excavator that tracks continuously, a piling rig crawls intermittently but every move is a full‑load event: the entire mast, rotary drive, and power pack traverse unprepared, often sloped, ground. The **track sprocket wheel assembly** is the mechanical conduit that translates travel motor torque into forward motion. For the ZR280, the correct sprocket is identified by part numbers **1031400162** and **1031400319**—assemblies that must deliver zero‑slip engagement, withstand abrasive spoil, and survive shock impacts without fracturing. Choosing a direct‑factory, metallurgically optimized replacement is the most impactful decision a foundation contractor can make for rig availability.

## CQCTRACK: The Manufacturing Source, Not an Intermediary
CQCTRACK, the international brand of Quanzhou Heli Machinery Manufacturing Co., Ltd., operates its own integrated steel foundry, forging workshops, heat-treatment furnaces, and multi‑axis CNC machining halls. There is no trading‑company layer. Each Zoomlion ZR280 sprocket is cast or forged, normalized, quenched, tempered, induction‑hardened, and final‑inspected inside a single, ISO 9001:2015‑certified campus. This direct‑factory identity means that the metallurgical record, hardness chart, and CMM dimensional report travel with the part, and the accountability for performance sits squarely with the manufacturer.

## Technical Definition of the 1031400162 / 1031400319 Sprocket Assembly
CQCTRACK engineers these sprockets expressly for the low‑speed, ultra‑high‑torque travel duty of a rotary drilling rig. The specification puts material toughness and tooth‑profile accuracy above all else, because a piling rig’s sprocket must endure ground engagement that would overwhelm an excavator component.

| Parameter | Specification & Engineering Intent |
| :— | :— |
| **Sprocket Body Material** | Forged or fine‑cast alloy steel (typically 40Mn2 or an equivalent Cr‑Mn‑Mo grade), chosen for high hardenability and exceptional Charpy impact values throughout the thick cross‑section. |
| **Tooth Surface Hardness** | Induction‑hardened to 52–58 HRC with a tightly controlled case depth. This provides a long‑wearing contact surface against the track bushings without creating a brittle tooth that could snap under shock. |
| **Core Toughness** | The un‑hardened core retains a refined, tough microstructure, guaranteeing that the entire tooth resists crack propagation even when the crawler’s grousers strike buried rock or concrete. |
| **Tooth Profile Accuracy** | CNC‑machined to the pitch‑circle diameter and involute form of the Zoomlion OEM drawing. Smooth roller‑sprocket load transfer eliminates the micro‑hammering that accelerates chain elongation. |
| **Heat Treatment Route** | Normalising → Quenching → Tempering, followed by tooth‑flank induction hardening. This sequence produces a continuous hardness gradient from the wear‑resistant case to the ductile hub. |
| **Mounting Hub** | Bolt‑hole diameters, PCD, pilot bore, and face run‑out machined to match the ZR280 final drive output precisely. Installation is bolt‑on with zero field modification. |
| **Casting/Forging Integrity** | Lost‑foam precision casting or closed‑die forging with ultrasonic and magnetic particle inspection to eliminate internal shrinkage, porosity, and surface‑breaking flaws. |

## CQCTRACK’s Manufacturing Capability: Total Process Ownership
**Manufacturing capability** at CQCTRACK is defined by vertical integration. The in‑house pattern shop produces the molds; the spectrometer‑controlled melting shop pours the alloy; the forging press shapes the grain flow; the CNC centers finish‑machine all critical surfaces; the digital induction‑hardening stations create the case; and the coordinate measuring machines verify every dimension against the master CAD model. Because no step is outsourced, lead times compress and quality becomes a continuous, recorded function rather than an inspection‑only gate. This is why a ZR280 sprocket from CQCTRACK arrives on‑spec every single time, regardless of batch size.

## Product Diversity: The Complete Undercarriage from One Source
While the 1031400162 / 1031400319 sprocket wheel is a high‑turnover drilling‑rig item, CQCTRACK’s **product diversity** extends across the entire crawler chassis. The same production ecosystem manufactures:
- Sealed and greased track chains with induction‑hardened pins and bushings
- Single‑flange and double‑flange bottom rollers with lifetime floating seals
- Front idler assemblies with tensioning yokes and recoil springs
- Track carrier rollers, track shoes (single‑grouser, triple‑grouser, swamp pads), and sprocket rims
- Components for Zoomlion, SANY, XCMG, Bauer, Soilmec, Komatsu, Caterpillar, Hitachi, Liebherr, and many more

For a foundation contractor running a mixed fleet of piling rigs and support excavators, CQCTRACK serves as a single, auditable supply base for all undercarriage wear parts.

## Quality Stability and Management Compliance Under ISO 9001:2015
**Quality stability** is achieved through an enforced **ISO 9001:2015** management framework that governs every operation. The system mandates:
- Spectrometer verification of every incoming steel heat
- In‑process ultrasonic and magnetic particle testing on sprocket blanks
- Dimensional audits against CAD‑derived acceptance windows using calibrated CMMs
- Batch‑level heat‑treatment records and hardness traverse reports
- Assembly run‑out checks and final preservation quality gates

This **management compliance** eliminates variability between production runs, ensures that the 1031400162 part delivered today matches the 1031400319 shipped last quarter, and forms the backbone of the company’s **sound corporate operation**—predictable output, on‑time container loadings, and the capacity to honor multi‑year blanket orders without disruption.

## Brand Recognition Built on Two Decades of Field Proof
The CQCTRACK brand carries **recognition** forged by performance in real ground conditions. It is known by aftermarket distributors, rig‑rebuilding centers, and foundation contractors across multiple continents as the manufacturer of sprockets that achieve dynamic interchangeability with OEM components and survive extended service intervals in abrasive, high‑load environments. This reputation is not the product of advertising; it is the accumulation of thousands of trouble‑free installations delivered year after year.

## The People Who Engineer and Deliver Every Sprocket

### Professional Technical Team
CQCTRACK’s **professional technical team** incorporates forging engineers, metallurgists, CNC programmers, and application specialists who analyze the actual duty cycle of a ZR280 rig. They understand that a piling rig sprocket sees long static periods punctuated by brutal torque spikes during repositioning. Their expertise translates into induction‑hardening patterns tuned for deep case endurance and material selections that resist the characteristic wear pattern of a drilling‑rig undercarriage. Technical inquiries receive answers backed by heat‑treat curves and material certifications, not assumptions.

### International Affairs Support Team
