painted the Transnet red, these machines
have an efficient centralised greasing and
fluid maintenance system. Other features
include a VEI load weighing system,
operator presence and engine protection
system, LED lighting, and a bucket
cylinder protection system.
According to Prakash Ramsumuj,
project manager for Transnet, it was
critical to minimise the period between
the arrival of a freight train and unloading
of materials. Improved efficiencies
within Transnet Freight Rail significantly
reduce lead times of materials to export
customers. “Due to our challenging
operating requirements and the
extremely corrosive environment in the
port, Transnet and HPE Africa engaged
in a highly effective joint design review
process after the tender award,” he adds.
Close collaboration between HPE
Africa and Transnet enabled the
assembly of all 10 specialised excavators
before the Transnet operational deadline
at the end of August 2018.

When size does matter
LiuGong’s wide range of excavators vary
from operating weights of 3.8 tons to 90
tons, and include zero tail and compact
excavators, medium-sized 20–30 tons
with standard and long-arm options, as
well as heavy-duty models in the 36-ton
to 90-ton range.
In 2016, LiuGong introduced its
945E and 950E model excavators to
the sub-Saharan Africa market — the
first of LiuGong’s ‘big size’ excavators
ranging between 45 and 50 ton
operating weights. The following year,
the 970E made its debut as the largest
in operating weight in platinum mining
in South Africa.
Since then, the 950E and 970E have
played a leading role for LiuGong in
the mining industry, increasing market
share through their use in gold, coal, and
platinum mines.
LiuGong’s joint venture with Cummins
Engines in 2013 led to improved engine

LiuGong’s 990F, with its 90

of the few models of this size
available in the market.

production, increased efficiencies, and
enhanced parts management for their
global operations.
The 950E model is equipped with
QSM11-type Cummins engine, and can
reach up to 400hp gross engine power,
with EGR cooling system and Cummins
patented VGTTM turbocharger, which
continuously varies the airflow boost
to precisely match engine rpm and
load demand for optimal performance.
The advanced hydraulic system-proven
negative flow hydraulics optimises the
main control valve and cylinders, and
improves the speed of the front-end
working equipment, while cutting down
on the hydraulic system’s damper loss,
resulting in a much better working
efficiency.
The 970E with 481hp Cummins
QSX15 engine is a power boost with
4.3m 3 standard bucket capacity and is
extendable for lighter material operations
such as coal.
LiuGong’s big size range is not limited
to the 36–70 tons range — LiuGong rolled
out 990F, with 90 tons operating weight,
powered by a Cummins EFI engine with
a rated power of 447kW, combined with
a 5.6m 3 bucket, making it one of the
few models of this size available in the
market.
