AFT 65 Scavatrice per trattori

AFT 100 è una scavatrice potente e robusta progettata per adattarsi all'attacco a 3 punti dei trattori da 60 - 120 hp (45 a 90 Kw)

The AFT65 has been constructed in modular form with a wide range of options to suit a great variety of jobs and different tractors

The ideal trencher for pipe and cable laying contractors, municipal authorities, agricultural contractors, farmers and anyone with trenches to cut and a standard tractor available.

IT OFFERS:

• High speed trenching - up to ten times faster than conventional backhoes.
  
  
• Cuts the narrowest trench size necessary for the job. Reduces reinstatement and backfill material costs.
  
  
• Mounted on a standard multipurpose agricultural tractor, it costs only a fraction of equivalent self-propelled trenching machines. Considerable savings not only in the purchase price, but also in long term running costs and maintenance.
  
  
• Twin soil augers neatly place the finely cut soil close to both sides of the trench for easy backfilling.
  
  
• 75 mm pitch fully detachable heavy duty digging chain.
  
  
• Easily exchangeable digging blades to cut trenches of 125, 150, 200, 300 mm wide or up to 450 mm with twin boom and chains.
  
  
• Choice of digging booms for maximum trench depths of 1.0, 1.15, 1.30 or 1.45 metres.
  
  
• Optional built-in hydraulic creep speed drive for tractors without creep speed gear boxes, giving a speed range of 0-300 metres per hour.
  
  
• Incorporated hydraulic oil cooling system
  
  
• Continuously variable hydraulic depth control, either manual or linked to a laser for accurate grading.
  
  
• Range of pipe chutes and pipe reel carriers available.
  
  
• Crumber with parallel self correcting linkage to maintain accurate trench bottom cleaning.
  
  
  

SPECIFICATIONS 

DIGGING CHAIN. AND TEETH
75 mm pitch heavy duty fully detachable roller digging chain fitted with hard faced austempered silicon manganese spring steel cuffing teeth, with optional tungsten carbide pick teeth for hard, abrasive soils.

TRENCH SIZES
A choice of 4 digging booms is available which will dig down to maximum depths of 1.00, 1.15, 1.30 or 1.45 metres. Digging teeth can be fitted to dig trenches 125, 150, 200, 250, or 300mm wide.

Twin booms and chains to dig trenches of 350, 400 or 450 mm wide down to 1 metre deep can be fitted as an alternative.

DEPTH CONTROL
Depth adjustment is by means of an hydraulic cylinder which can be manually operated from the tractor valve lever or linked to automatic laser grading systems with a solenoid valve.

TRANSMISSION
The digging chain is driven by the tractor PTO shaft through a torque limiting safety clutch and right angle gear box. Different splines are available to suit your tractor.

PIPE LAYING CHUTE
Three sizes which will feed, and lay perforated land drainage pipes up to 80, 110 or 150mm diameter

WEIGHT
from 900-1100 Kg depending on optional systems fitted.

 
TRACTOR REQUIREMENTS
Power: 50 to 80 hp (35-60 kW)
Three-point linkage: category: 2 or 3.
PTO shaft: 540 rpm.
A front mounted backfill blade or counterbalance weights are normally required.
A reduction gear box of 10:1 or more is recommended . If not available, the optional Creep Speed Drive can be built into the trencher. (Not for use with turf tyres) With the built-in creep speed drive, the maximum trenching speed will be controlled by the hydraulic supply provided by the tractor: 25 Lt/min gives a maximum speed of approx. 165 mtr/hr and 45 Lt/min around 300 mtr/hr.
