This 1650L is the larger of the two
South American built bulldozers that
Case is now bringing into Europe.
New scrap handler
versions
There are now two scrap handler
versions of CX240B and CX210B with
the Isuzu AH-42H21X engine. Also
equipped with the now proven
hydraulically elevated cab, these SL
machines have operating weights of
30.1 and 25.3 tonnes respectively.
The CX210B-SL made its European
exhibition debut at Bauma in April. It
has a straight, rather than curved, 6.8m
boom and a 5.2m goose neck dipper
Its operating envelope embraces a maximum attachment pin height of 12.8m and a maximum forward reach of
11.1m.
Attachments for the CX210B-SL include four or five tine grabs weighing up to 1145kg. The larger CX240B-SL can
be equipped with four, five or six tine grabs that can be raised to a higher attachment pin height of 14.4m.
The new MH and SL tracked machines allow Case to offer customers with an alternative to its longer established
WX210MH and WX240MH wheeled excavators with materials or industrial handling equipment. Whilst wheels can
provide faster mobility around a site, tracks provide better stability and higher lifting capacities.
European debut for dozers
Monthyon is also being used to demonstrate the Case 1650L – one of two bulldozers that had their official European
launch at Bauma. Case has been building this sort of machine in the USA and other associated markets since it
bought the American Tractor Corporation (ATC) in 1956.
At one time Case also made some tracked dozers and loaders in Cornwall in the UK but since the mid 1980s these
products have been absent from Europe despite the production of machines across the Atlantic. Now the 1650L and
the smaller 1150K Series 3, which are produced in the Case factory in South America, are in Europe.
The 1650L and 1150K have operating weight ranges of 16.0 to 17.0 tonnes and 12.6 to 13.3 tonnes respectively.
They both have Case Tier 3 emissions compliant engines – with power ratings of 107kW (144hp) and 88kw (118hp) –
teamed with Rexroth PowerStat hydrostatic transmissions.
The engine in the 1650KL at Monthyon was a 6-cylinder, direct common rail Case Family IV 667TA/EDJ. It delivers
a peak torque of 669kN at 1400rpm - useful low down torque for dozing applications. Electronic fuel injection and a
charged air cooler help to maximize engine power and improve fuel efficiency.
The conventional low drive tracks get their power through the variable axial piston pumps and motors of the dual path
hydrostatic transmission. The use of a drive
shaft between the engine and the hydrostatic
pumps helps reduce machine vibration,
thereby improving operator comfort.
The undercarriage has pinned equaliser
beam suspension to aid stability and provide
the traction needed for work on slopes as well
as pushing hard at low speeds and carrying
out demanding tasks such as stump removal.
A test drive of the machine revealed that
the hydrostatic transmission operated
smoothly and allowed power turns with a full
The 1650L’s narrow instrument panel and
tapered bonnet allows a clear view of the front
of the tracks and both sides of the PAT blade.
