15Tons Middle Excavator


15Tons Middle Crawler Digger As an innovative heavy-equipment manufacturer in China, LANTYPC Group has been specialized in producing wheel loaders and crawler excavators of high quality, reliability and durability for more than 20 years, including 15tons crawler digger. This W2150-8 15tons hydraulic excavator is widely used in urban construction and building, and mining. It is equipped with a 0.53m3 bucket and an original ISUZU engine. This ISUZU engine can provide 72.7kw power at the rated speed of 2200rpm.     
Parker valve, Doosan travel motor and Sungbo swing motor match the pump perfectly. And the use of well-known Kawasaki hydraulic pump provides larger displacement to allow for stronger power, higher efficiency and higher productivity of this 15tons middle crawler excavator. 
Automatic idle speed avoids unnecessary fuel consumption, so this hydraulic excavator is energy-saving and environment friendly. Meantime, this 15tons crawler digger features high reliability, high efficiency, excellent operation comfort, high serviceability and high productivity. 

Features of Hydraulic Excavator:

1.The imported ISUZU engine of 15tons crawler digger features great power and effective environment protection. 
2.This hydraulic excavator is equipped with Isuzu original oil/water separator and secondary grade oil filter to guarantee the high quality of the fuel and to extend the service life of the engine. 
3.Strengthened frame alleviates the potential injury of the operator when accidents happen. Meanwhile, the strengthened arm, boom and frame allows for longer service life.
4.An audio entertainment system can relax the operator after or during a long time of operation. 
5.Joystick control makes it easier and more comfortable to operate this middle crawler digger with higher sensitivity and the control accuracy of arm and bucket movements are increased. 
6.An air-suspension seat can be adjusted into different proper position to get an excellent visibility and better lumbar support. 
7.Mounted on silicon shock absorbers, the cab provides outstanding operator comfort with low noise and less vibration. 
8.Ergonomic design for the spacious cab and advanced ESS electrical control system suitable for different working conditions. 
9.The pipeline, connector and negative flow hydraulic system are all famous Parker brand. 

Hydraulic Excavator Parts and Features:


The ISUZU BB-4BG1TRP engine provides stronger power with lower fuel consumption. This engine is mounted on the upper carriage with damper to reduce the vibration and noise. To better protect the engine, a steel cover is hinged to the cross beam. 

2. Cab: 




The spacious cab of 15tons crawler digger is equipped with an air conditioner, shock absorbing seat and radio. The seat can be adjusted into 6 different directions. The durability of the cab is improved by the model and structural design of large cross section. And the hydraulic system can be locked by the safety locking bar to avoid misoperation. 

3.Hydraulic parts (pump, valve):

The Kawasaki hydraulic pump and Parker valve offer large displacement and high pressure. The power curve perfectly matches the engine curve to allow for smooth and reliable operation. 

4. Structural parts(bucket, chassis):


The high-stress areas are reinforced by cast steel and high-strength steel panels to make this hydraulic excavator more durable and reliable, and these high-stress areas are at boom, arm, bucket, chassis and more. The design of these structural parts is advanced and rational
