Features

PERFORMANCE AND PRODUCTIVITY

  • Cat C7.1 delivers exceptional power and fuel efficiency unmatched in the industry.
  • Automatic engine speed control activates during no- or light-load conditions which reducing engine speed and minimizing fuel consumption.
  • Electronic controls govern the fuel injection system, and feature improved filtration, ensuring reliability of fuel injection components. The number of fuel filters is reduced and change Intervals extended to maximize profit.
  • Cat C7.1 offers a completely new and improved cooling system. Standard cooling fan is directly driven from the engine. Optional programmable reversible fan allows for radiator blowout, increases service intervals and optimizes engine operating temperatures. Optimum fan blade pitch is calculated based on the target engine speed, coolant temperature, and hydraulic oil temperature.
  • Forestry designed hydraulics give power, efficiency and controllability unequaled for high performance in all forestry applications.
  • Boom and stick regeneration circuits save energy during boom-down and stick-in operation increasing efficiency, reducing cycle times and pressure loss for higher productivity and increased fuel efficiency.
  • New improved swing drive system provides 20% higher swing torque.
  • Hydraulic system offers precise control reducing operator fatigue.

LONG TERM VALUE AND DURABILITY

  • Outer frame utilizes curved side rails, which are di-formed for excellent uniformity and strength.
  • ROPS certified box-section channels improve upper frame rigidity under the cab.
  • Inverted U-channels span the width of the main frame and are formed, rather than fabricated, for superior strength and reduced weight.
  • Boom tower and main rails are constructed of solid, high-tensile strength, steel, and reinforced at boom foot.
  • Swing drive area is reinforced into the main frame rails supporting high stress loads such as those encountered in grapple saw or harvester applications.
  • Advanced, reinforced, purpose-built car body stands up in the toughest forest applications.
  • Upper structure weight and stresses are distributed evenly across the full length of the track roller frame.

OPERATOR COMFORT AND CONTROL

  • Workstation is spacious, quiet and comfortable, assuring high productivity.
  • Controls, joysticks and an ergonomically designed seat are strategically placed to reduce operator fatigue.
  • Equipped with warning lamp and buzzer for critical engine oil pressure, coolant temperature and oil temperature. Filters and fluid change intervals are available in the main menu.
  • Multi-Information Display contains information important to the operator and is 40% larger with four times the resolution of the previous model.
  • Comfortable air suspension seat provides a variety of adjustments to suit the operator's size and weight including fore/aft, height settings. Wide adjustable armrests and a retractable seat belt are also included.
  • Joystick controls have low lever effort and are designed to match the operator's natural wrist and arm position. The operator can operate joystick controls with an arm on the armrest and the horizontal and motions reduce operator fatigue. Exclusive proportional control and push buttons are programmable to operator personal preferences, allowing maximum productivity.
  • Consoles feature a simple, functional design reducing operator fatigue, easing switch operation and providing excellent visibility.
  • Forestry cab is designed with heavy-duty guarding, meeting all ROPS/FOPS/OPS requirements.

OPTIONS TO MEET YOUR NEEDS

  • Cat Log Loader is purpose built for forest applications. Straight boom design and matched stick provide optimum reach and lift performance.
  • Grapple Saw and Slasher configurations provide flexibility for processing trees to meet a variety of requirements.
  • Cat GF machines can be equipped with bucket, thumb, stump pullers and clearing grapples to fit a wide range of forest road and site preparation jobs.
  • Can be configured as a Feller Buncher with auxiliary pump, and line groups for hot saw hydraulic requirements.
  • Harvester hydraulic and linkage attachments allow configuring as a harvester or road side processor.

HEAVY DUTY CONSTRUCTION

  • Log Loader model comes standard with Heavy-Duty/Long undercarriage using standard 320D2 L Excavator 191 mm (7.5 inch) pitch link assemblies and rolling components. New double saddle mounted Carrier Rollers have been added to increase undercarriage life.
  • Heavy-duty carrier rollers with dual supports assure superior endurance.
  • Heavy-duty track rollers stand up to the toughest forest applications with greater sealability, higher resistance to deformation and greater load carrying capacity.
  • 10% larger bushing diameter extends external bushing wear life.
  • 15% increase in link height increases link wear life.
  • 36% wider bushing strap improves bushing-to-link retention.
  • Engine radiator fan is completely enclosed by fine wire mesh guard, reducing the risk of an accident.
