Bosch Rexroth A10VG variable hydraulic pump for the Tadano Faun crane FA036 99707033422 5161234 5243015

The A10VG is a swashplate-type axial piston pump with variable displacement, designed primarily for closed-circuit hydrostatic drive applications. In plain terms: it converts mechanical energy from the crane's diesel engine into hydraulic flow, and it can vary how much flow it produces on demand — rather than pumping a fixed amount all the time like a gear pump would.

That variability is the whole point. A crane doesn't need the same hydraulic flow crawling through a job site at 2 km/h that it needs cruising down a highway at 80 km/h. The A10VG's variable displacement lets the system adjust output to match real-world driving and operating conditions, which improves both fuel efficiency and drivetrain responsiveness.

Why Tadano Faun Chooses the A10VG for Its Crane Fleet

Tadano Faun, the German engineering arm of the Tadano Group and a long-established name in all-terrain and mobile crane manufacturing, uses hydrostatic drive systems extensively across its crane lineup — particularly in the travel drive and, on many models, in auxiliary functions like fan drives. The A10VG fits this application profile for several practical reasons.

1. Precision Speed and Torque Control

Cranes operate in two very different worlds: highway travel and creeping, centimeter-precise positioning on a job site. The A10VG's variable displacement allows the crane's hydrostatic drive to deliver high torque at low speed for maneuvering around obstacles, then shift toward higher speed/lower torque output for road travel — all without a mechanical gearbox doing the heavy lifting.

2. Durability Under Cyclical Loads

Crane duty cycles are brutal on hydraulic components: constant starts, stops, direction changes, and load swings. The A10VG's piston-and-cylinder-block architecture is engineered to handle high-pressure cycling far better than vane or gear pumps, which matters when the pump might see thousands of load-reversal cycles over its service life.

3. Compatibility with Electronic Crane Management Systems

Modern Tadano Faun cranes rely on electronic control architecture to coordinate engine management, transmission behavior, and outrigger/stability systems. Electrohydraulically controlled A10VG variants integrate cleanly into this environment, allowing the crane's control unit to modulate pump displacement in real time based on sensor feedback — engine load, wheel speed, operator input — rather than relying purely on mechanical feedback loops.

4. Reduced Fuel Consumption

Because the pump only produces the flow the system actually needs at a given moment, engine load drops during partial-demand conditions. For crane operators running long shifts, that efficiency gain adds up in fuel costs over a season.

How the A10VG Fits Into the Crane's Hydrostatic Drivetrain

To understand where the A10VG sits in the system, it helps to walk through the basic flow of power:

1. Diesel engine delivers rotational mechanical power to the pump's drive shaft.

2. A10VG pump converts that rotational energy into hydraulic flow, with displacement (and therefore output) varied according to swashplate angle.

3. Hydraulic lines carry pressurized oil to a hydraulic motor (often a Rexroth A6VM or similar variable-displacement motor) mounted at the axle or wheel hub.

4. The hydraulic motor converts the flow back into rotational mechanical energy, driving the wheels.

5. Charge circuit and control valves manage internal pressure, cooling, and direction (forward/reverse) throughout the loop.

This pump-motor pairing — sometimes called a hydrostatic transmission — replaces or supplements traditional mechanical transmissions in certain travel and creep-speed applications, giving Tadano Faun cranes stepless speed control without clutch engagement shock.

Q1: Which Tadano Faun crane models use the A10VG pump?

A1: The A10VG family is used across multiple Tadano Faun all-terrain crane platforms in their hydrostatic travel drive systems. Exact model and displacement variant depend on chassis size and axle configuration, so technicians should confirm the specific part number against the crane's parts manual rather than assuming a universal fit.

Q2: How do I know if my A10VG pump is failing?

A2: Common warning signs include sluggish travel response, inability to reach top speed, unusual pump noise (often linked to charge pressure loss), visible fluid leaks at the shaft seal, or elevated particle counts in oil analysis. Any of these warrants inspection before the issue escalates.

Q3:What is the price and delivery time of the A10VG hydraulic pump for the Tadano Faun crane?

A3: The specific price and delivery time will depend on the equipment model or specific product model you provide.
