7.2 TECHNICAL INSTRUCTIONS
SWE18UF is an all hydraulic track excavator with beautiful appearance, 360° rotatable flat roof,
680mm long small rear end, all of these ensure the work in limited place.
The engine is YANMAR 3 cylinder water-cooling diesel engine which has a normal rated power
of 13.4kW/2200rpm. Use flexible supporting breadthwise
，
install the engine at the rear end of
machine.
Air filter is a customized equipment of
FPG042545
; safety device (optional) on engine inlet pipe
ensures more safety and stability of the engine.
Large capacity water tank with air exhaust device for the engine cooling system can effectively
protect engine and ensure normal work in high temperature and prevent overheating.
The main pump and engine directly connected with coupling, maximum work pressure is 21
Mpa.
Use flexible shaft coupling installed in the diesel motor flywheel to drive the main pump,
perfectly avoid the influence on main pump, which is caused by the vibration of diesel motor.
Hydraulic system and pilot system
Hydraulic pump, main valve, drive motor and swing motor are products of China, Japan, Korea
and Italy respectively with perfect quality and stable work condition ensuring the stable work of
the whole system.

Full power qualified system can make full use of the engine power.

Abortively matched drive control element can ensure the good control of the whole
machine.

The system can appropriately distribute and make use of flow to improve and promote
the machine performance.

High pressure double speed travel motor provides high traction and travel speed.

Adopt a 18.6L oil tank to supply the oil pump.

Oil pump supply oil to the entire working device through multi-way valve, and the oil
comes back to oil tank through oil cooler and magnetism papery filter.

The pilot control mechanism in cab can ensure the multi-way valve action.

The gear pump connected with main pump can supply hydraulic oil to pilot oil passage.

The high precision high-pressure filter in pilot oil passage can avoid interferer from
outside.
Hydraulic oil cooling
We adopt aluminium oil air exchanging cooler. Hydraulic oil can be perfectly cooled.
Fuel device
Diesel tank can be supplied from a 24.6L fuel tank, the compact and appropriate design makes it
very easy to add fuel and clean.
