ORIGINAL EQUIPMENT
HD Hyundai introduces new dozer
and a bevy of excavators
HD Hyundai recently announced several new additions to its
portfolio of off-highway machines. The expansion includes the
HD100 dozer, the HX355A excavator, and a quartet of new
models for its HX-A series of compact excavators. The HD100
is Hyundai's first new crawler dozer model.
" The new HD100 dozer will be a great addition to the equipment
fleets of earthmoving contractors, forestry, waste handlers
and other customers who already enjoy the benefits of
using Hyundai wheel loaders and excavators, " said Mike Ross,
senior VP, HD Hyundai Construction Equipment North America.
More with less
The HD100 dozer is reportedly designed to deliver more power
and superior traction than comparable 10-ton dozers.
Hyundai states that the machine's undercarriage includes dual-flange
rollers outside the chain of the track and singleflange
rollers inside the chain of the track to ensure the track
stays on the undercarriage and reduce wear.
The HD100 has a standard blade capacity of 2.9 yd3
(2.2 m3
)
and a digging depth of 1.5 ft (457 mm). It is powered by a 115
net hp (86 kW) Hyundai G2 DM03 engine that meets Tier 4
Final emissions standards paired with a hydrostatic transmission.
The top speed of the HD100 is 5.6 mph (9 km/h).
Standard operating weight of the HD100 is 23,589 lb (10,700
The cab features pushbutton start, an 8-inch color touchscreen display
and more efficient heating and air-conditioning.
operators themselves on what they thought about the
units, " said George MacIntyre, product manager for backhoe
and tractor loaders. " That gave us a lot of insights into what
we were going to do. One was obvious - the electrohydraulic
controls, which tie in perfectly with the battery-powered
machine versus the pilot-controlled unit on the 580SN. "
Advanced telematics with two-way communication and
remote diagnostics allows fleet managers to stay informed on
how the machine is operating. A built-in EV care maintenance
program comes standard with a three-year, 3,000-hour preventative
care package and a three-year, 3,000-hour warranty
on the high-voltage electrical system, which includes the batteries,
motors and battery management system.
Dolan said a common question from customers centers on
EV pricing compared to diesel-powered machines. " Yes, the
battery-powered electric machines may cost more upfront, "
he said, " but they can bridge the gap by lowering costs for
maintenance and fuel. "
The 580EV electric backhoe loader has been approved for
the California CORE (Clean Off-Road Equipment) voucher incentive
program, which encourages users in the state to purchase
or lease currently commercialized zero-emission offroad
equipment. " So, we're excited about that, " Dolan said.

contact pressure is 5.6 psi (38.6 kPa) with a standard blade. An
LGP (low ground pressure) option is available when ordering
the dozer with a wider 10 ft, 7 in (3,226 mm) blade vs. the standard
8 ft, 11 in (2,718 mm) blade, along with track shoes that are
4 in (102 mm) wider than the standard shoes. The LGP package
lowers overall ground pressure to 4.2 psi (29.0 kPa).
Compact-radius design
Hyundai also announced the new HX355A LCR 35.5-ton compact-radius
excavator. The HX355A slots between the
