About the LR65

The LR50 is CZM’s smallest model of the Long Reach series, which is mounted on a CAT 323 Next Gen. It has a special designed boom with 2 lift cylinders which allows for a higher torque and crowd force to be applied to the tool, which aligned with interlocking Kelly bars makes it efficient on rock and hard soil drilling. Round Friction bars are also available for high production on softer soils. The long reach configuration makes it ideal to applications such as sound bearing walls, transmission lines and utilities, drilling on a steep slopes, and difficult to reach holes.
Base:
  • The new Cat 323 Next Gen is a purpose-built machine powered by a fuel-efficient U.S. EPA Tier 4 Final C7.1 ACERT engine.
  • Equipped with CAT Vision Link that allows management to monitor machine operations and maintenance data online and wireless, providing information such as location, hours, fuel usage, idle time, event codes and maintenance schedule.
Mast:
  • Reinforced mast, with high resistance steel Weldox 700.
Main Winch:
  • Special groove for better cable winding and longer cable life.
  • Press-roller included.
  • 2 gears allows for both high speed and high pulling force.
  • Automatic gear shifting, for seamless operation, high production.
  • Automatic down the hole winch stop. When Kelly bar reaches the bottom of the hole, winch automatic stops.
  • Free willing winch during crowd operation.
  • Hydraulic and mechanic brake.
  • Hydraulic measurement of pulling force displayed in the cabin for operator.
Rotary:
  • Robust design, with 2 slewing bearings on top and bottom, robust pinion and main gear.
  • Anti-cavitation and anti-shock system for longer hydraulic motor life.
  • 1 group of Hydraulic Motor / Planetary Gear for high torque, high speeds and long life.
  • Cooling system for hydraulic motors and gearboxes.
  • Power-shift for High spin-off speed (120rpm) for quick discharge of soil.
  • 3 operation speeds and 3 spinoff speeds. For high torque and high speeds.
  • Automatic gear shifting, for seamless operation, high production.
  • Exchangeable keys, bolted. No need to rebuild keys by welding inside the rotary.
  • Hydraulic measurement of torque displayed in the cabin for the operator.
Cab:
  • AM/FM Radio, Air conditioning/Heating.
  • ROPS cab & Top protection.
  • LCD monitor for Engine and Hydraulics computer, with diagnostic system.
