The Volvo BM A35 is a highly regarded model in the world of articulated dump trucks (ADT), known for its robustness, reliability, and versatility in various construction, mining, and heavy-duty applications. Manufactured by Volvo BM, a division that has evolved into Volvo Construction Equipment, the A35 was designed to handle tough terrains and large payloads, making it a staple in industries that demand high performance and durability from their machinery.
This article provides an in-depth look into the Volvo BM A35, its operational features, maintenance requirements, and a guide to understanding the key aspects of the truck, including its manual and troubleshooting tips for common issues.
Volvo BM: A Legacy of Innovation
Volvo BM, a branch of the Volvo Group, has a long history in manufacturing construction equipment. The company initially made its mark in the 1950s and grew steadily into one of the leading names in heavy machinery. Known for its innovation, Volvo BM became especially famous for its ADTs, which feature a unique articulated design that allows for better maneuverability and payload management compared to traditional rigid trucks.
The A35 model was part of Volvo BM’s evolution in producing highly capable, versatile vehicles for industries requiring the transportation of heavy materials over difficult terrains. The A35 was specifically designed for operations where access was limited, and high load capacities were essential, such as quarries, large construction sites, and mining fields.
Key Features of the Volvo BM A35
The Volvo BM A35 is an articulated hauler, which means it features a pivoting joint between the cab and the dump body, giving it improved flexibility and handling, especially in off-road conditions. Here are some of the key specifications and features of the A35:
1. Engine Power and Performance

• The A35 is equipped with a powerful diesel engine capable of delivering substantial horsepower to tackle heavy-duty tasks.
  
• The engine is designed for efficiency, providing a balance between power output and fuel consumption. This allows the truck to perform well under load without excessive fuel use.
  

2. Hydraulic System

• The A35 utilizes a robust hydraulic system that powers the dumping mechanism, steering, and other critical operations. The hydraulic system is essential for lifting the dump bed efficiently, even under full load, and allows operators to move materials quickly and effectively.
  

3. Articulated Steering

• One of the defining features of the A35 is its articulated steering, which provides excellent maneuverability. This allows the truck to navigate rough, uneven, and confined spaces more easily than rigid-frame trucks.
  

4. All-Wheel Drive

• The A35 is an all-wheel-drive vehicle, which provides additional traction and stability when driving over difficult or loose surfaces, making it ideal for working in mud, snow, or sand.
  

5. Load Capacity and Dumping Mechanism

• With a robust carrying capacity, the A35 is designed to haul substantial loads (around 35 tons) of material, ideal for large construction projects and mining operations.
  
• The dumping mechanism is designed for efficiency, allowing for quick and complete unloading of materials, minimizing downtime.
  

Volvo BM A35 Manual and Maintenance
For operators and maintenance personnel, understanding the operation and maintenance of the Volvo BM A35 is essential to ensure the truck performs at its best. The A35 manual provides detailed information on operating procedures, troubleshooting, and maintenance practices.
1. Daily Maintenance Checks

• Engine Oil and Fluids: Checking engine oil, hydraulic fluid, and coolant levels is essential for ensuring the truck runs smoothly. Low levels can cause overheating or poor performance.
  
• Tire Inspection: Inspecting tires for wear and proper inflation helps prevent operational downtime and improves the truck’s fuel efficiency.
  
• Brakes and Steering: Inspecting the braking system and ensuring the articulated steering mechanism is free of obstructions is important for safe operation.
  

2. Scheduled Servicing

• Regular servicing intervals are vital for keeping the Volvo BM A35 in peak condition. This includes periodic oil changes, hydraulic system checks, and ensuring that the drive train components are lubricated properly.
  
• Servicing the hydraulic system regularly ensures that the truck’s lifting and dumping capabilities remain reliable.
  

3. Hydraulic System Care

• One of the most critical aspects of the A35’s maintenance is the hydraulic system. Over time, seals and components can wear out, leading to reduced efficiency or failure of critical systems like the dump bed or steering.
  
• Regular inspection and replacement of hydraulic filters and seals are essential for avoiding leaks or system malfunctions.
  

4. Electrical Systems and Controls

• The electrical systems, including the lighting, control panel, and sensors, should be checked regularly to ensure everything is functioning properly. Faulty wiring can cause malfunctions in the vehicle’s operational systems, including the transmission, brakes, and engine diagnostics.
  

Common Issues with the Volvo BM A35
While the Volvo BM A35 is a highly durable machine, like any piece of heavy equipment, it can face issues over time. Here are some common problems that A35 owners may encounter:
1. Hydraulic Leaks

• Hydraulic leaks are a common issue in articulated dump trucks due to the high pressure within the system. Over time, seals and hoses can deteriorate, leading to leaks that affect the dumping system and steering.
  
• Solution: Regular inspection of hydraulic hoses and seals is crucial. If any leaks are detected, they should be repaired immediately to prevent damage to the system.
  

2. Steering Issues

• The articulated steering mechanism can develop issues, such as stiff steering or unresponsive handling. This is usually due to hydraulic failure or worn-out components in the steering system.
  
• Solution: Regular maintenance of the hydraulic steering system and checking the articulation joints for wear and lubrication can help avoid steering problems.
  

3. Engine Performance Problems

• Engine issues like rough idling, difficulty starting, or loss of power are not uncommon, particularly in older models. These issues can be caused by clogged fuel filters, low fuel pressure, or worn-out engine components.
  
• Solution: Keep fuel filters clean, ensure the fuel system is pressurized properly, and replace any worn-out engine components to maintain performance.
  

4. Brake Failures

• Brake issues, such as poor braking response or uneven wear, can result from hydraulic system malfunctions or air in the brake lines.
  
• Solution: Regularly check brake fluid levels, inspect the brake lines for leaks, and bleed the brake system to maintain proper brake function.
  

Conclusion
The Volvo BM A35 is a powerful and reliable articulated dump truck that has earned its place in heavy-duty industries like construction and mining. By adhering to regular maintenance schedules and addressing common issues promptly, operators can ensure the truck performs efficiently for many years.
Understanding how to properly maintain the A35, along with utilizing the truck’s manual for troubleshooting, will keep the machine running smoothly and extend its lifespan. Whether you're using the A35 for moving heavy materials across a construction site or navigating rough, muddy terrains, this vehicle’s performance and dependability make it a valuable asset for any fleet.
