It is a small steel gun that comes and goes freely in the farmland garden.

It is a smart and energy-saving green angel.

It is the Star of Trinity Round Dig.——SY65W

Wheel digging light riding，Ingenuity is important。SY65W It is a small wheeled excavator product created by Sany Heavy Machinery.，Its wheelbase is long、Run fast、The stability is strong，Bring greater return on investment for customers。

SY65W Around the fourth national aircraft“New Power”、“New look”、“New technology”New upgrade，Have“Energy saving and high efficiency、Durable and reliable、Low maintenance cost、Intelligent driving”And so on，It is suitable for sand and stone fields、Municipal construction、Urban transformation、Farmland、Water conservancy and other projects。New upgrade，Excellent performance1、Hydraulic system，Overall promotion：Equipped with electric control load-sensitive hydraulic system，Electronically controlled variable displacement pump + Load sensing main valve，Regulate the flow by controlling the current，High sensitivity、Quick response。Independent development of constant power algorithm，Realize the engine / Pump / Valves are efficiently matched，Improvement of comprehensive energy efficiency ratio of complete machine operation 5%。Reasonable optimization of main pump power distribution，Boost Travel Mode Power，Travel speed increases 11%。

  

2、Boom Stick Upgrade：Boom stiffener thickness increased to 6mm，The intensity is higher。Boom rear support、The center support is made of forging.，Avoid local welding stress concentration，And that durability is improve。Wear resistant plate is used for the front end of the arm，Longer life。The shaft sleeve adopts laser cladding technology.，More wear resistant。

3、Travel speed is increased：Imported drive axle and transmission，The bearing capacity is up to 8 tons，Higher reliability，Travel speed increases 8%，The re-matched transmission ratio is perfectly combined with the hydraulic system.。

4、Stick wear is reduced：Open type is adopted O Ring Structure，And is convenient to install，Effectively prevent foreign matters such as sand from entering the end face of the bucket rod，Slow down the wear rate。

5、Motor optimization：High voltage independent variable performance optimization，Increase the speed stability of driving in the high gear on the slope.。

6、The cab is comfortable and beautiful：Control system upgrade，Exquisite and modern interior design，Chair back rotation angle from 22.2°Increase to 33.3°，Facilitating the activity and rest of the operator。The entire cab is lengthened 50mm，Increase in height 50mm，Space increases 10%。Adopt new sealed black technology，The sealing performance is further improved，Cab leakage is approximately as low as119.7m3/h，Indoor noise is about as low as 74dB。
