Turbine snow blowers

Turbine snow blowers are used to remove large quantities of snow when moving forward to clear a path, to widen a path (to the left or to the right), to open roads through mountain passes and also to load snow into tipper trucks. They can be mounted on tool carriers or on the front of tractors fitted with an F1 (formerly Setra), or F2 or 3 point coupling plate (Categories 2 and 3).

Turbine snow blowers work in two stages:

  • The first stage cuts the snow using two coaxial steel drums that bring the snow to the center of the snow blower.
  • The second stage ejects the snow using the very high speed impeller which in turn directs it out of the discharge chute

This two stage system means that snow can be discharged over considerable distances.

The snow blower is mounted on two manually adjustable pads used to bear a part of the snow blower’s weight while reducing its ground friction surface. A Hardox 400 steel blade is positioned under the turbine snow blower to scrape the snow and leave a minimum amount of snow and ice left over after it passes.

Transmission

Depending on the type of vehicle used for mounting the turbine snow blower and how it is equipped, there are two ways of powering a snow blower:

 

By mechanical transmission: Using a drive shaft attached to the vehicle’s power take-off.

Power required from the power take-off (min/max): 35 to 320 kW

 

 

By hydraulic transmission: Compatible with vehicles equipped with hydraulic systems with enough power.

Characteristics

ARVEL proposes a full range of turbine snow blowers to meet every user’s needs in terms of size, weight, power and type of usage.

Here are the main characteristics of these models:

  • Snow clearing width: 1,300 to 2,800 mm
  • Drum height: 600 to 1,100 mm
  • Snow clearing capacity: Up to 10,500 m3/h

To make it easier to use the turbine snow blower and to ensure the best possible snow clearing effectiveness, a large number of functions are hydraulically controlled:

  • Discharge chute rotation,
  • Deflector adjustment to vary the discharge distance,
  • Raising/lowering the turbine snow blower
  • Lateral oscillation to pivot the turbine snow blower by +/- 10° in relation to the horizontal axis.

Safety

A unique and innovative safety system fitted with mechanical clutch type torque limiters protects the rollers in hydraulic mode, avoiding the need for the usual time consuming procedure for replacing the shear-off pins normally used.

A by-pass valve in the discharge chute rotation circuit protects the latter if any severe stress is applied to it.

Pressure wheels

Adjustable pressure wheels can be installed in place of the standard pads so that the turbine snow blower can follow the road, especially through bends.

Loading chute

Where the snow cannot be “ejected” to the side of the road (on mountain roads), the turbine snow blower can be fitted with an extended loading chute instead of the standard discharge chute so that snow can be sent to a tipper truck running alongside the snow clearing vehicle.

Hydraulic tilt adjustment

As standard, the turbine snow blower tilt adjustment is made manually. You can replace this system with a hydraulic cylinder controlled from the cab.

Forced lubrication

A pump on the hydraulic circuit is used to ensure a constant fluid flow through the drive system thereby optimizing its cooling.
