For heavy machinery, distribution logistics, and mining industries, steering system integrity is paramount. The Pitman arm links the truck's steering gear shaft to the drag link, converting angular rotation into lateral steering control. Given the extreme vibrational stress, heavy payloads, and corrosive environmental exposure, servicing steering systems on major trucks like Sinotruk HOWO and Shacman F3000 presents substantial challenges.
Over time, road salt, chemical exposure, and rust cause the splined shaft of the steering box to seize onto the Pitman arm. Attempting removal without a specialized tool leads to impact damage on steering gear components.
High-torque Pitman arm pullers provide axial pulling force while preventing torsion transfer to the steering box seals. This keeps heavy commercial trucks in service with minimal maintenance downtime.
Proper service tools prevent micro-fractures in high-strength carbon steels, ensuring steering systems comply with global road transport safety regulations.
A heavy-duty Pitman arm puller must handle significant mechanical stress. Standard tools often fail under tension, showing jaw deflection or thread stripping. Our professional-grade pullers are built to counter these issues through robust engineering.
Our heavy-duty pullers are forged from ASTM 4140 Chrome-Molybdenum Steel or 8620 Nickel-Chromium-Molybdenum Alloy. This raw material undergoes a double heat-treatment process:
Designed for medium to heavy commercial vehicle classes:
| Jaw Spread Capacity | 75mm - 120mm (3" to 4.75") |
| Jaw Throat Depth | 85mm - 110mm (3.35" to 4.3") |
| Rated Pulling Force | Up to 15 Metric Tons |
| Drive Hex Size | 1-1/8" or 1-1/4" Impact Rated |
Founded in 2014 in Deyang City, Sichuan Province, and expanded with a 196,000 square meter factory in Chengdu, Hongkai has built an integrated production system for heavy-duty truck distribution and maintenance tool supply chains. This setup allows us to leverage precision tooling resources directly linked to heavy truck assembly lines.
Our tools are manufactured using automated forging presses, precision CNC machining centers, and automated heat-treatment furnaces. This advanced setup guarantees structural consistency across production batches.
We offer tiered pricing structures and custom OEM branding to support distributors, importers, and global fleet operators.
