8750 Draglines

Cat® draglines offer the lowest material removal cost per ton, consume less power and emit fewer greenhouse gases than other methods of overburden removal, making them the most productive and environmentally friendly excavators in the industry. The Cat® 8750 is our flagship model. It’s the first dragline of any kind to be successfully equipped with AC IGBT drive systems — a superior technology developed for the sole purpose of making your loading operations more productive, predictable and safe. And like all Cat draglines, the 8750 is supported by a team with a century of experience, institutional knowledge and unmatched expertise.

Features

SAFETY

  • Ingress/egress doors, with rear door featuring level floor to prevent trip hazards, particularly in cases of emergency where rapid exit from the cab is necessary.
  • Superior visibility with full operator-to-boom point line of sight, plus maximum operator situational awareness provided by five optimally mounted cameras and operator cab mounted overhead displays.
  • Safe and convenient access with non-skid material on roof and shoe walkway surfaces to prevent falls, and serrated bar grating stairs, platforms and walkways that facilitate safe movement around the machine.
  • Unique three seat design that accommodates operator, trainer and maintenance person; observer's seat positioned behind operator to provide maintenance personnel with the operator's view while them to monitor operator actions; and separate operator and trainer emergency stop buttons.
  • Safety-enhanced electrical system, with emergency stop system that is hardwired dual string with safety relay; all operator interface controls that are 24 volt; available Arc Flash evaluation; single point of motion disable for mechanical maintenance of machine; key interlocking to prevent access to incoming High Voltage connection areas; and stored energy warning signs installed.

CONFIGURED FOR EACH SITE

  • Application engineers who work collaboratively with mines, considering factors such as digging environment, mine life, mine plan and annual production targets to determine the proper dragline configuration for each customer's mine site.
  • Engineers who analyze mine environments and apply the findings to recommendations for new draglines as well as upgrade recommendations for existing dragline fleets.

OPERATOR CAB

  • State-of-the-art operator cab that is the product of a multi-year collaboration between Caterpillar, mining companies and operators.
  • Provides industry-leading visibility with excellent line of sight supplemented by optimally mounted cameras and display screens.
  • Reduced cognitive fatigue and enhanced productivity via the intuitive and visually aesthetic display screens.
  • Effortless operation and improved control response resulting from new Hall Effect joysticks (patent pending), with custom-designed ergonomic handles and “finger touch control” spring tension.

SERVICEABILITY

  • Improved service access with walkways across the machine, plus easy accessibility to the base via manholes inside and outside of roller circle path; revolving frame access, which improves the ability to move from section to section throughout all compartment spaces; raised platforms for swing, brake, blower and electrical termination maintenance; substantial walkways/work areas around deck-mounted machinery and electrical equipment; and ready accessibility to hoist and drag drums via stairs, walkways and platforms.
  • Overhead cranes that provide coverage to most major components.
  • Easily accessible maintenance point for lube servicing.
  • Robust exterior flood lighting brackets that allow changing of flood lights from walkways and platforms; and machinery house internal highbay lighting that is accessible from boxes with quick opening hatches on top of roof.

DURABILITY

  • Boom and Tri-Structures manufactured using impact-resistant, high-strength steel with select welds of full penetration, profiled and ground type.
  • Structural welds that undergo visual inspection, with critical welds also receiving MT, UT or X-ray inspection; and large furnaces used to stress-relieve critical weldments.
  • Base frame assembly that features radial design to optimize load and access, forged integral center pintle, stress-relieved “T-section” roller path sub-weldment and thick bottom plate with abrasion resistant steel wear plates and anti-skid cleats.
  • Large diameter machined crowned rollers, with a third rail that eliminates flanged rollers, which allows the addition of more rollers to significantly extend service life.
  • AC components located in sturdy, mine-grade cabinet, with reliability features including major control and power electrics that are derived from the transportation sector, allowing for high temperature ratings, shock and vibration ruggedness, and longevity of component availability; IP 54 enclosure that is liquid cooled, transferring heat out of machinery house; cabinets that allow optimized cable routing; and cable internals that are organized to allow efficient access to internal components.
