5 USE CONDITIONS

This loader is a multi-purpose large construction machine mainly used for bulk materials. It is

widely used in mineral yards, construction, roads, freight

yards and ports. It can be used for dragging, to flatten the

ground, piling and stacking of bulk soil, sand, sand stone,

coal and garbage.

It can chuck wood, fork grass, clean snow and

chuck box-liked material with proper work equipment.

Please refer to CHAPTER III – 3.5 Operations for

details.

WARNING

The following operations are forbidden for the loader:

1. Over loading.

2. Unbalanced.

3. Digging hard material.

4. Lifting heavy material using a rope hung directly on the bucket.

Dig with the bucket above the machine level.

6 CIRCUMSTANCES REQUIREMENT

Requirements for this machine as follows:

1. Altitude: ≤3000m;

2. Temperature: -15~40

℃;

3. Water depth: ≤500mm.

The loader is a general construction machine, and can be used under the conditions listed in this

manual. Please follow the rules and utilize relative specific purpose equipment. If it is used under

other conditions or potentially dangerous circumstances, such as areas with flammable materials,

explosives and asbestos dust, the manufacturer assumes no responsibility for the potentially resulting

damage and injury.

7 FEATURES

z Luxury streamline structure, widen of engine cover backside, beautiful appearance.

z LG956L loader employs Weichai, Shangchai or Cummins engine to reduce oil consumption by

10%; also employs large capacity and double transmission assembly, and change the transmission

ratio to increase the average power and tracing property of the whole machine.

z Both the wheel base and tilting load are large, so the vertical stability is high.

z Larger engine hood, hexagonal window bar and high efficient radiator are used, air intake and

output rout are optimized to reduce the water or oil temperature so that the life of whole machine

is improved.

z The optimized structure of rock arm and bucket to satisfy the working condition mostly. The

main plate employs wear-resistant steel board to increase the wear resistance. The domestic

LG956L mounts with rock bucket to increase the bucket property.

z Jingled frame structure, large steering angle (38°) and small turning radius, so it is mobile and

flexible; the frame employs tapered roller bearing jingled style to improve the using life.

z The hydraulic system classifies into two types, one is full hydraulic fluid amplifier steering

hydraulic system and double pumps confluence working device hydraulic system, and set

unloading valve on the steering system to utilize high voltage small flow and low voltage big

flow, so the power of hydraulic system increases obviously and the oil consumption and noise

reduces to improve the tracing property of whole machine further. The other is full hydraulic load

sensing steering hydraulic system and single pump large flow working device hydraulic system,

turn stably and lift quickly to improve the productivity.

z The optimized and improved hydraulic pipe seal structures are fully used to improve the sealing

performance and reliability of the whole machine hydraulic system.

z Optimized shock absorption system to supply better operation environment; new type of the

shock absorption seat with better shock absorption ability supplies the driver with better

comfort-ability.

z LG956L double pedals loader has the function of selecting to cut off power, the power can be cut

off when braking, so the reliability of brake system elements improve to satisfy more working

condition.

z Optimized structure of fuel tank, enlarged cubage, and adding protective rear steel board.

z New type of large view operator cab, full-sealing design, optimized air-rout, air blowing from

front. Luxury vehicular decoration, air condition and warm wind outside, operation space is

larger and comfortable.

z Employ low pressure and wide base, so the cross running and passing performance is good to

satisfy the driving and working on the rugged road.
