P&H Cranes, once a prominent name in the crane industry, have left a lasting impact on construction and heavy machinery sectors. The brand has been associated with robust and reliable machinery, often seen at major construction and mining sites. However, as time progresses, many of these machines, especially older models, face maintenance challenges due to the scarcity of parts. This article explores the legacy of P&H Cranes, common maintenance challenges, the procurement of used parts, and provides insights into keeping these machines operational.
P&H Cranes: A Brief History
P&H (Pittsburgh-Des Moines Steel) was a key player in the crane manufacturing industry, producing cranes, draglines, and other heavy-duty equipment for mining, construction, and industrial purposes. They were recognized for their exceptional engineering and durability, often being the go-to choice for large-scale construction projects.
The company produced both wheeled and crawler cranes, designed to handle enormous loads and navigate challenging terrains. Over the decades, P&H became synonymous with industrial strength, with its products being widely used in the mining industry, particularly for strip mining and other heavy-duty tasks. However, after a series of mergers and acquisitions, the brand was eventually absorbed by Terex Corporation, marking the end of an era.
Challenges with Older P&H Machines
With years of service, older P&H cranes are encountering more frequent maintenance issues. These machines, while still powerful, often face problems like:
Maintaining a P&H crane, especially an older model, requires expertise and a keen understanding of its inner workings. Here are some tips for keeping these machines in optimal condition:
Finding replacement parts for P&H cranes, particularly older models, is a challenging but necessary task. Here are some options for sourcing used parts:
Case 1: The New Jersey Bridge Project
A construction company in New Jersey found themselves relying heavily on an old P&H 4100 XPC crawler crane for a bridge replacement project. The crane, though decades old, had been well-maintained and still showed great promise. However, the team ran into problems when the hydraulic pump failed, and they couldn’t find an exact replacement part. They turned to a local salvage yard that specialized in mining machinery and located a similar pump from an older crane model. With some adjustments, the pump fit, and the crane was back in action, allowing the project to continue without significant delays.
Case 2: The Arizona Mine
An Arizona mining company continued to operate a fleet of P&H 2570 shovels, all purchased during the mid-1980s. Over the years, parts began to wear out, particularly the boom cylinders. Faced with high replacement costs, the company decided to explore used parts options. They sourced several key components through an online auction site specializing in heavy machinery. With proper installation and testing, the crane ran smoothly for several more years, saving the company hundreds of thousands of dollars in replacement costs.
The Future of P&H Cranes
While newer models are continuously entering the market, older P&H cranes are still being used in several industries. Their ability to withstand harsh conditions and perform under heavy loads has ensured their longevity in many fields. As more and more operators focus on maintaining and reviving these older machines, the demand for used parts will likely continue to rise. However, it will require dedication, expertise, and a resourceful approach to keep these legacy machines running efficiently for years to come.
Conclusion
P&H cranes have cemented their legacy as one of the most reliable and durable brands in the heavy machinery industry. Despite the challenges posed by aging equipment and the difficulty in sourcing parts, these cranes remain in service due to their solid build and continued value to industries worldwide. For operators of older P&H models, the key to longevity lies in diligent maintenance, smart procurement of used parts, and a network of resources that can help sustain these cranes for the long haul. With a combination of hands-on care, patience, and perseverance, old P&H cranes can continue to perform and deliver results, proving their enduring worth in today’s ever-changing machinery landscape.

Challenges with Older P&H Machines
With years of service, older P&H cranes are encountering more frequent maintenance issues. These machines, while still powerful, often face problems like:
- Wear and Tear: As with any long-standing machinery, mechanical parts wear down over time. Components such as hoists, cables, and hydraulics often need more frequent attention.
- Obsolete Technology: Older P&H cranes may still be running on outdated technology, making it difficult to integrate with modern equipment or repair with newer diagnostic tools.
- Parts Availability: One of the biggest challenges for owners of older P&H machines is finding replacement parts. Due to the brand’s absorption by Terex, some original components are no longer manufactured, and aftermarket parts may not always match the specifications or quality of the original parts.
Maintaining a P&H crane, especially an older model, requires expertise and a keen understanding of its inner workings. Here are some tips for keeping these machines in optimal condition:
- Regular Inspections: Schedule frequent checks for vital components, especially hydraulics, electrical systems, and mechanical parts like bearings and gears.
- Lubrication: Consistent lubrication can prevent the premature wear of critical parts. Ensure that all moving components are adequately lubricated to reduce friction and extend their lifespan.
- Hydraulic System Care: The hydraulic system is a crucial part of any crane. Check the oil levels, inspect hoses for wear, and regularly clean the filters to prevent clogging.
- Electrical Checks: Given that many older cranes were built before the widespread use of advanced diagnostic tools, make sure to check the wiring and control panels frequently. Malfunctioning electrical systems can cause severe damage if ignored.
Finding replacement parts for P&H cranes, particularly older models, is a challenging but necessary task. Here are some options for sourcing used parts:
- Online Marketplaces: Websites dedicated to heavy machinery, such as eBay, often feature used P&H parts for sale. It's vital to vet the sellers for quality assurance and authenticity of the parts.
- Salvage Yards: Some specialized yards that deal with industrial machinery salvage offer parts from decommissioned P&H cranes. Visiting these yards might uncover hidden treasures for owners of these older machines.
- Parts Re-manufacturers: Some companies specialize in remanufacturing crane parts. They can recreate obsolete components to the original specifications, giving owners a reliable and cost-effective option for replacement.
- Networking with Other P&H Owners: Forums, online groups, and local associations of crane operators often share valuable advice and may offer leads on used parts.
