Volvo BL70 Backhoe Loader Overview and Background
#1
The Volvo BL70 is a versatile backhoe loader designed to combine power, durability, and comfort in one compact machine. As part of Volvo Construction Equipment’s long legacy of producing high-quality machinery, the BL70 builds on decades of engineering expertise, customer feedback, and innovative design. Volvo Construction Equipment boasts over 80 years in the industry, with a solid reputation for reliability, productivity, and environmental care.
Volvo as a company dates back to 1927 and has since become synonymous with robust construction machinery that balances powerful performance with operational safety and durability. The BL70 model specifically was crafted in response to direct customer input during its development phases, ensuring the machine fits practical jobsite requirements across various industries including construction, agriculture, and municipal works.
Technical Specifications and Performance
The BL70 operates with a Volvo 4.0-liter, four-cylinder turbocharged diesel engine, delivering approximately 90 horsepower (67.1 kW). This powertrain ensures reliable and efficient operation under demanding conditions. The backhoe loader features four-wheel drive with hydrostatic power steering for maneuverability in tight spaces and challenging terrains.
Key performance parameters include:
  • Dig depth of about 173 inches (439 cm), allowing for deep trenching and excavation tasks.
  • Hydraulic system capacity of approximately 35.7 gallons (135.1 liters) with a pressure operating around 3625 psi (249.9 bar), providing strong hydraulic force essential to loader and backhoe operations.
  • Hydraulic flow rate reaching 42 gallons per minute (159 liters per minute), enabling fast, responsive loader and backhoe movements.
  • Loader breakout force exceeding 12,445 pounds, ensuring speed and ease for heavy lifting and material handling.
The loader arm and boom design incorporate strengthened pivot points and simplified construction for longevity and improved weld penetration. The dipper arm includes an extendible feature with increased clearance from the cylinder to prevent damage and ensure smooth operation.
Operator Comfort and Safety Features
Recognizing that operator comfort translates into higher productivity, Volvo engineered the BL70 with an ergonomic cab that offers excellent 360° visibility through flat glass windows with minimal distortion. The cab is spacious with adjustable tilt steering, cushioned flooring, and ample storage space, complemented by strategically placed ventilation, heating, and optional air conditioning systems.
Control ergonomics are addressed with a multi-function pilot-operated joystick that simplifies loader functions—raising, lowering, tilting, and operating the bucket with precision yet minimal effort. The joystick also integrates buttons for transmission forward/reverse and connection/disconnection to speed up cycle times.
Safety is paramount with integrated features such as:
  • Retractable seatbelt and rearview mirrors.
  • Interlocking brake pedals offering single or double pedal modes for tighter turns and better control.
  • A single key for all locks including doors, fuel cap, ignition, and toolbox, helping prevent vandalism.
  • Battery disconnect switch to avoid unauthorized machine use.
  • Heavy-duty loader safety strut that secures the loader arm when raised for safe maintenance.
Maintenance and Serviceability
Volvo designed the BL70 for easy maintenance, which directly impacts machine uptime and operational costs. The tilt-up hood provides ground-level access to the engine and major components, allowing quick checks and fluid refills. Grouped service points make routine daily checks fast, including coolant expansion tank, air filters, and oil fill points.
The hydraulic and transmission oil cooler tilts for cleaning accessibility. Greasing intervals are set at 50 hours, minimizing downtime. Components use corrosion-protected fittings and O-ring face seals to ensure lasting hydraulic integrity. Electrical connectors are waterproof and snap together easily.
Attachments and Versatility
A noteworthy feature of the BL70 is the quick-change attachment bracket on the loader. This allows operators to switch between various Volvo loader attachments quickly without leaving the cab, enhancing productivity with multi-purpose capabilities. Attachments from other Volvo compact and mid-range wheel loaders are also compatible, expanding the machine's versatility on diverse projects.
Stabilizer legs and flip-over pads are designed for maximum ground contact and extended wear on hard surfaces. Optional guards protect hydraulic cylinders for heavy-duty applications.
Legacy and Market Presence
The BL70 has continued Volvo’s tradition of delivering compact backhoe loaders that blend the power of full-sized machines with the agility of smaller equipment. Its sales volume has been significant worldwide, supported by Volvo's extensive global dealer network, ensuring parts availability and after-sales support.
The backhoe loader market is competitive, with the BL70's unique combination of Swedish engineering quality, operator-focused design, and robust performance making it a favored choice in many regions. It has been a reliable workhorse for contractors handling excavation, loading, landscaping, and infrastructure projects.
A Story of Practical Impact
In one notable construction project in Scandinavia, the Volvo BL70 played a crucial role in urban redevelopment. Operators praised the machine for its visibility and maneuverability in narrow streets while delivering the power necessary for trenching and material movement. The operator’s station comfort and precise control helped reduce fatigue during long shifts, ultimately contributing to the project's timely completion and safety standards.
Suggestions and Solutions for Buyers
When considering a BL70 purchase, potential owners should evaluate their workload to optimize attachment choices, as the machine’s quick-change system allows adaptation to multiple tasks, reducing the need for multiple pieces of equipment. Regular maintenance as per Volvo’s guidelines is essential to maximize uptime and machine life.
Potential improvements or solutions for aging BL70s include upgrading to telematics systems like Volvo's CareTrack, which provides real-time machine and operator data to improve fleet management and maintenance planning.
In summary, the Volvo BL70 is an enduring and adaptable backhoe loader that embodies Volvo's engineering prowess and commitment to safety, comfort, and sustained performance. Its development history, solid technical specifications, and design features cater well to the broad needs of today’s construction and excavation industries.
