TG154A Triple Grouser Track Shoe 154mm Pitch Forged from 23MnB Boron Alloy Steel for Mini Excavator Undercarriage

Product Overview

The TG154A Triple Grouser Track Shoe is a quality aftermarket component for 3-5 ton class mini excavators. With a 154mm pitch and 450mm width, this shoe serves the popular PC35, PC45, CAT 304, and 305 market segment. Forged from 23MnB boron alloy steel, each shoe delivers consistent quality through precision die forging and controlled heat treatment (HRC 38-44). The triple grouser profile ensures smooth, low-vibration operation — a key requirement for rental fleet machines and urban construction sites. Each shoe is CNC-machined for bolt hole accuracy and finished with anti-corrosion black paint for storage protection.

Key Features

• Compact Excavator Design: 154mm pitch specifically for 3-5 ton mini excavators including PC35, PC45, CAT 304, 305 models
• Triple Grouser Smooth Operation: Low-vibration operation ideal for rental fleet machines and surface-sensitive job sites
• Forged 23MnB Steel: Consistent quality through precision die forging with controlled heat treatment
• Universal Bolt Pattern: Standard 4-bolt M16 pattern compatible with most 3-5T class mini excavator track chains

Technical Specifications

Factory Strength

Our manufacturing facility spans over 20,000 square meters equipped with advanced forging production lines, CNC machining centers, and automated heat treatment furnaces. We operate 8 die forging hammers (1T-10T capacity), 12 CNC turning/milling machines, and 4 continuous mesh-belt quenching & tempering furnaces with precise temperature control. Annual production capacity exceeds 500,000 track shoes. Every batch undergoes rigorous quality inspection including dimensional gauging, hardness testing (HRC), ultrasonic flaw detection, and magnetic particle inspection. We hold ISO 9001:2015 and ISO 14001:2015 certifications, with SGS/Bureau Veritas third-party inspection available upon request. Our in-house metallurgical lab ensures consistent 23MnB/25MnB boron steel composition and optimal heat treatment parameters for maximum wear resistance and impact toughness.

Quality Control Process

1. Incoming raw material inspection with spectrometer analysis
2. Forging temperature monitoring and die wear inspection
3. Post-forging dimensional check on sampling basis (1 per 50 pcs)
4. Heat treatment hardness verification (HRC 40-48 on grouser surface)
5. Magnetic particle inspection for surface crack detection
6. Final dimensional inspection with go/no-go gauges
7. Anti-corrosion coating and packing inspection

Applications

Compatible with Komatsu PC35, PC45, CAT 304, 305, Hitachi EX35, EX40, and similar 3-5 ton mini excavators. Ideal for landscaping, residential construction, utility installation, and rental equipment.

Frequently Asked Questions

Q1: How many shoes for a PC35?

A standard Komatsu PC35 uses 38-42 track shoes per side (76-84 total). Count your existing shoes or provide track chain model for exact quantity.

Q2: Can these be mixed with existing OEM shoes?

Yes, our TG154A shoes are dimensionally compatible with OEM shoes. For best results, we recommend replacing all shoes on a chain together, but individual replacements are technically possible.
