74 t XCMG Heavy Mining Motor Grader — Perkins 2806D-E18TA / 447 kW
74,000 kg, 447 kW heavy mining motor grader — the top tier of the XCMG mining grader line. Perkins 2806D-E18TA 18-liter diesel at 447 kW / 2,100 rpm. 16,430 mm overall length, 7,300 mm × 1,025 mm blade — 50 percent longer and 49 percent taller than the 4,877 mm × 686 mm board on the 32-ton GR3505T Pro. 12.5 m minimum turning radius. Eight forward gears with 42.7 km/h top speed, four reverse gears. Traction force at least 390 kN (f=0.75) — 144 percent above the GR3505T Pro's 160 kN. 30 percent maximum gradeability, EU Stage III emission.
The XCMG GR5505T Pro is a 74,000 kg, 447 kW mining-class motor grader — the heavy tier of the XCMG mining grader line, sized for large open-pit haul road maintenance, mine bench leveling on heavy substrates, and large-area mining yard grading.
The GR5505T Pro runs the Perkins 2806D-E18TA at 447 kW / 2,100 rpm — a 18-liter Tier diesel, an order of magnitude larger than the 6.7 L Cummins in the 16-19 ton 5 Series tier. 74,000 kg operating weight (2.3 times the 32-ton GR3505T Pro), 16,430 mm overall length, 4.56 m wide × 4.81 m tall. 7,300 mm × 1,025 mm blade — 50 percent longer and 49 percent taller than the 4,877 mm × 686 mm board on the 32-ton GR3505T Pro. 12.5 m minimum turning radius. Eight forward gears (4.6 to 42.7 km/h), four reverse gears (4.5 to 32.6 km/h). Traction force at least 390 kN (f=0.75) — 144 percent above the GR3505T Pro's 160 kN. 30 percent maximum gradeability, EU Stage III emission. Suited for the largest open-pit mining operations where haul road segments and bench widths exceed what the 32-ton tier can finish in one productive pass.
Five aspects of the GR5505T Pro that fit it to heavy mining motor grader work: 18-liter Perkins powertrain, top-tier chassis weight, blade configuration, traction, and application fit.
447 kW / 2,100 rpm rated power from the Perkins 2806D-E18TA 18-liter six-cylinder diesel — a Caterpillar/Perkins industrial engine platform sized for heavy mining duty. Significantly more displacement than the Cummins QSM11 11 L in the 32-ton GR3505T Pro sibling. EU Stage III emission certified.
74,000 kg operating weight — 2.3 times the 32-ton GR3505T Pro and the heaviest tier in the XCMG mining grader line. 16,430 mm overall length, 4,560 mm wide, 4,810 mm tall. 12.5 m minimum turning radius — fits large open-pit benches and wide haul road segments where the smaller mining graders run out of single-pass coverage.
7,300 mm × 1,025 mm blade — 50 percent longer and 49 percent taller than the 4,877 mm × 686 mm moldboard on the 32-ton GR3505T Pro. The tall 1,025 mm height handles deep material loads on heavy mining substrates without overflow; the long blade matches haul road segment widths at large open-pit operations.
Traction force at least 390 kN at f=0.75 — 144 percent above the GR3505T Pro's 160 kN, reflecting the 2.3× chassis weight transferring to ground load. Eight forward gears (4.6/5.9/8.7/11.7/17.7/25.1/32.2/42.7 km/h), four reverse gears (4.5/8.7/17.2/32.6 km/h). 30 percent maximum gradeability.
Specified for the largest open-pit haul road maintenance, heavy mine bench leveling, and large-area mining yard grading where smaller tier graders need multiple passes per cycle. The 7,300 mm blade and 390 kN traction fit operations where single-pass throughput on haul roads drives fleet productivity.
