Product Description

Product Description

20TON Road Roller SEM520 with Imported Engine High Power

Product Features:

• Closed center hydraulic system
  * Improves efficiency by 20% over the open center system
  * Reduces oil contamination, prolongs life of hydraulic system
  * Maintains higher pressure and smaller energy loss
  * Allows for simpler hose routing
  * Requires smaller volume hydraulic tank, reduces maintenance cost
  Application/Versatility
  * Applications include road, railway, airfield and industry yard compaction
  * Optional diamond shape pad-foot roller for compacting clay soils
  * Optional square shape pad-foot roller for compacting sandy materials
  High efficiency
  * 50mm drum, compaction performance is 10%~15% better than competitors
  * Isolated modular cooling system, works in ambient temperature of 43 ºC
  Reliability
  * Vibration system utilizes an eccentric vibe pod design, extends life up to 50%
  * Closed center hydraulic system, world famous piston pump and motor
  * Electronically controlled transmission, easy and comfortable to operate
  Operation
  * Digital frequency meter, monitors compaction frequency
  * Three level alarm system and Engine speed guage monitor machine performance
   
  Comfortable and safe control system
  1 >Suspension seat with safety belt and occupation switch >Foldable ROPS provides safety protection under extreme conditions >Driving safety and reliability is guaranteed by three means of braking: neutral brake, secondary brake and parking brake. >Propel lever integrates vibration, water sprinkling and braking functions; >Foot type oil spray switch, easy to operate; >Bilateral accesses, large area step design, safe and reliable. Efficient operating performance
  2 >The front drum and rear tire combination greatly improves the compacted surface quality of asphalt top layer; >Dual-frequency single-amplitude vibration exciter provides two kinds of exciter forces for different working conditions. >67Hz high frequency vibration and high excitation force ensures high compaction efficiency and deep influence. >Manual and automatic vibration control >720mm large diameter drum design, good traffic performance, high compaction quality; >Tubeless tires, high reliability, easy maintenance, ensure the continuity of construction. Environmental friendly and energy saving
  3 >Diesel engine in compliance with EU Stage-V emission standards >ECO engine speed ensure the power output in environmental friendly and energy saving manner; >LED lights; >Disposable hydraulic oil as option; Superior trafficability
  4 >Two gear speeds available; >High climbing ability, small turning radius; >Normally closed brake; >Independent support structure with two motors for rear drum, high power and smooth turning; >High curb clearance, superior edge compaction performance.
  Excellent maintenance space
  5 >75 degree opening angle of engine hood facilitates service >Front and rear driving lamp holder can be turned out, which is convenient for the maintenance of electrical lines, sprinkler system and scraper. >Air filter, machine filter, diesel filter and hydraulic oil filter are centralized lower placed within easy reach; Superior trafficability
   
  High Efficiency 10% greater excitation force than other products in the same category resulting in 16.7% greater production.
  Extended Life Time The use of water wheel type lubrication on the vibratory bearing extends the bearing life up to 5,000 hours. The engine air filter is raised and the air is filtered twice to protect the engine. The hydraulic system contains three-stage filtration.
  Operator Comfort Cab mounted on vibration damping mounts. Cab temperature control. Operator control forces have been reduced.
  Safety Features Rounded bumpers front and rear. The large rear glass and sloped hood for greater visibility.
