Let’s discover its assets...
Assets
The perfect fit for steel mill slag handling
•
Hydrostatic drive provides excellent maneuverability in confined space.
•
Factory designed and built to withstand high temperatures, abrasive and dusty environments.
•
Excellent breakout force for faster digging and loadout.
•
3.02 m³ (3.95 yd3) bucket capacity optimizes the cycle times and minimizes the machine exposure to heat.
•
Excellent front and rear operator visibility.
•
Specific slag bucket with thicker steel and larger teeth.
•
Sealed track with four shoe options; Flat, Double Grousers, Alternate Flat and Double Grousers,
Triple Grousers.
•
Synthetic, fire-resistant hydraulic fluid provides excellent lubricity for long power train and hydraulic
component lives.

Guarding and thermal protection
Built to withstand high temperatures, dusty and abrasive environments
Extensive guarding provides more uptime and longer life.
•
Heavy duty front guard provides extra protection
against slag.
•
Heavy duty bottom guards protect the engine
and power train.
•
Side bars welded on the track roller frame strengthen
and protect it.
•
Anti-abrasion guards protect the final drive seals.
•
Heavy duty bumper protects the cooling package
against rear impacts, maintains good visibility
and adds additional counterweight.
•
Tilt cylinder guards protect the cylinder rods and seals.
•
Floating solid pins on lower bucket linkages ease
the bucket maintenance.
Thermal protection reduces heat transfer
and improves overall system reliability.
4
•
High temperature seals are used in the equalizer bar,
idlers, track rollers, pivot shaft, carrier rollers, lift
cylinders, tilt cylinders and final drives.
•
High temperature braiding protects wiring harnesses
from heat and abrasion.
•
Thermal insulation or heat deflectors are added to the
front guard, equalizer bar rubber pads, air cleaner hose,
bottom guards, enclosure doors, fuel tank, lift cylinders
head end, tilt lines, lift lines, hydrostatic lines and fuel lines.
•
Synthetic, fire-resistant hydraulic fluid provides excellent
lubricity for extended wear life.
•
The fuel tank cap features a combination of pressure
relief device and a flash spark arrester.
Cab protection
State-of-the-art Steel Mill cab
•
Heavy Duty windshield glass laminated for strength.
•
A metallic screen is attached to the windshield grill to
reduce the heat radiated to the glass. This maximizes the
glass protection while maintaining good front visibility,
•
A metallic shield is added to the bottom of cab doors
to protect the windows against slag projections.
•
The windshield grill is hinged to allow quick access
for cleaning.
•
Silicone material is used on windshield, side windows
and cab doors seals, front baffles, front and rear wiper
blades and door stoppers.
•
Metal is used instead of plastic for door handles
and push button release.
•
The cab floormat and the lights are heat and fire resistants.
•
Steel plate on top cab greatly reduces radiant heat
transfer into cab.
Operator station
Superior comfort and visibility
•
Automatic air conditioned and reduced sound level
cab keeps the operator focused and comfortable.
•
Rear visibility and lighting is much improved for a
better visibility. The total number of lights is four at
front, two at rear and two facing sideways. All lights
are guarded.
•
A manual brake release system is located in the cab
for reliability and convenience.
•
Steps and grab irons are added to the back of the
machine to provide a rear access.

Steel Mill Bucket and Tracks
Built to last
Slag bucket
Slag bucket is heavily reinforced and equipped with larger teeth
for longer life. Welds are made with high yield-strain material.
Tracks
Four track shoe types are available for the sealed and
non‑lubricated tracks:
6
•
Double grousers – lowest cost; good traction in loose slag
•
Triple grousers – less damaging to paved surfaces
•
Flat – Best for paved areas
•
Alternate flat and double grousers – good for paved
surfaces, but still provides good traction in loose material
Operating Recommendations
Machine exposure to hot slag
The 973D Steel Mill Arrangement has modifications that allow the machine to handle hot slag for
limited time periods.
Exceeding the following recommendations will prevent the machine from meeting expected
performance levels.
•
The time of exposure to hot slag for a machine should be less than 15 minutes per hour to allow
adequate cooling time between cycles.
•
Multiple machines are usually required to meet the time limits of exposure to hot slag.
•
Typically, two machines per furnace and a backup machine for the site provide the best uptime.
•
The timing, frequency and duration of the work and cooling cycles for the machines may
be different for each job site.
