Snow blowers before winter: overhaul, overload guard, parts

Below, we go through the items in Zaugg's overhaul, where the overload protection and wear parts are located on the Monoblock blowers and the railway equipment, and what Zaugg says about ordering parts in good time.

What the summer overhaul covers

Zaugg's service sheet for the summer overhaul of snow blowers lists the following:

• Thorough cleaning
• Corrosion protection and lubrication
• Lubrication of all moving parts and gear oil change, to extend service life
• Maintenance of the overload protection
• Inspection and adjustment of the working hydraulics
• Function check of the moving mechanical parts: bearings, chute alignment and the mounting device
• Condition check of the blower unit: drive bearings, milling drum, impeller and housing
• Inspection of wear parts
• Inspection of the paintwork, with touch-ups or repainting

The point is to find the wear before winter

Zaugg describes the overhaul as maintenance and inspection in which all components are checked for wear and damage. Zaugg's German flyer on the summer overhaul states that the aim is to avoid costly repairs.

The overload protection

Maintenance of the overload protection is a separate item in the overhaul. This is how the protection is built on the Zaugg machines:

• Monoblock 230 and 380 — shear bolt coupling on the impeller and automatic safety clutches on the milling drum
• The SF 72-70 and SF 115-125 railway snow blowers — automatic safety clutch on the impeller in case of overload
• The track plough behind the K10-Vario wedge plough — adjustable overload protection

The wear parts in contact with the ground

Zaugg describes the parts in contact with the ground on the railway snow clearing equipment and the Monoblock 380 as follows:

• SF 72-70 — the blower has a steel wear blade. The distance from the wear blade to the top of the rail is set with the vehicle's lifting device
• K10-Vario — the wedge plough has PUR wear blades, and the distance from the front plough blades to the top of the rail is adjusted with adjustable wheels
• The track plough behind the wedge plough — the wear blade is made of high-strength plastic, with a shape agreed individually
• Monoblock 380 — the cutting edge is in two parts, with a safety blade that can fold back

Order wear parts early

Zaugg asks customers to plan their need for spare and wear parts for the next winter season early. Zaugg's reasoning is that the time it takes to obtain raw materials and traded goods varies greatly, and that ordering early allows the overhauls to be planned with confidence and secures the wear parts for the season.

For the Monoblock 230 and 380, Zaugg has a dedicated spare parts kit for rectifying faults quickly. The kit contains relays, solenoid coils, fuses, sensors, microswitches, directional valves and potentiometers, among other things, and the point is that a defective component can be replaced straight away, without waiting for the part.

Training and remote diagnostics

Zaugg runs courses for drivers and maintenance technicians through ZAUGG Academy, and offers remote diagnostics with ZAUGG Connect, where early warnings are designed to make it possible to plan maintenance in advance.

Width, power and tipping load for the Monoblock are covered in the guide Snow blower on a wheel loader, and the railway equipment is described in Snow clearing on railways.
