The V43 tooth holder is an important accessory for construction machinery such as excavators and loaders. Below is a detailed introduction to its features, applications and material characteristics:
| Product Features | 1.Structural Design: It adopts the Super V vertical locking system paired with the V43PN dedicated elastic pin. The locking surface is automatically updated upon replacement, offering strong fatigue resistance. Some models feature a Twin Tiger (double-pointed) or streamlined tip design to enhance penetration power. | 2. Performance Advantages: Hardness reaches 48-52 HRC, impact toughness ≥15J (25℃), tensile strength ≥1450N/mm², combining wear resistance and strength; the slim-tipped tooth design reduces resistance and lowers fuel consumption by more than 30% | 3. Adaptability: Compatible with 35-40 ton excavators and loaders (such as Komatsu PC300, Hitachi ZX450), and can be used with adapters such as the 5856-V43 series. | 4. Convenience: The vertical drive pin design enables quick replacement, is less affected by mineral powder clogging, and reduces maintenance downtime by 40%. |
| Material Characteristics | 1. Basic Material: Made of high-strength alloy cast steel, with some models containing low-carbon alloy components. It is formed through precision casting (lost-wax casting) plus forging process, resulting in a dense internal structure | 2. Mechanical Properties: Yield strength ≥ 1100 N/mm², Brinell hardness 470-520 HB, combining wear resistance and fracture resistance, suitable for rock impact environments. | 3. Quality Certification: Complies with the ISO 9001:2008 standard, and material composition can be customized and adjusted according to engineering requirements. | |
| Product Usage | 1.Core Scenario: Suitable for medium to high-intensity engineering operations, including rock excavation in quarries, hard soil breaking during pipeline laying, and stripping operations in open-pit mines, among other harsh environments. | 2. Compatible Equipment: Compatible with Komatsu, Hitachi, Volvo and other brand 35-40 ton excavators, wheel loaders, and front-end loaders. | 3. Industry Applications: It is widely used in construction, mining, road infrastructure, and other fields, especially suitable for working conditions that require the dual needs of 'penetration power + wear resistance'. | |
