Product Detailed
Vibration System aa Compaction performance is made more effective and over a wider range of soil conditions due to a double fre

Vibration System• Compaction performance is made more effective and over a wider range of soil conditions due to a double frequency and double amplitude design.  A Caterpillar patented eccentric vibe pod design modulates vibe amplitudes via a completely sealed inner cavity containing free flowing steel shot.  This design allows for more stable and reliable vibe amplitudes, as well as reduced impact forces on the vibe system resulting in an overall cleaner system vs. the more traditional vibe systems that utilize steel eccentric weights that impact or ‘hit’ each other each time the vibe system is activated.• The overall design of the vibe system allows for more convenient maintenance and service.• The thickness of vibrating drum shell is 50mm compared to a 40mm thick drum shell typically used in the industry.  This thicker drum shell allows for a heavier drum, which enhances the compaction performance, thereby improving work efficiency.• Maximum vibe system reliability has also been achieved by utilizing World Class vibe bearings.Powerful Engine System• The assembled Weichai DEUTZ Engine of German technology complies with the China National Stage II Emission Standards.  This engine utilizes turbocharged and inter-cooled technology for compressing and cooling inlet air before being delivered to the cylinders, along with an increase in airflow and oxygen intake by the combustion chamber, which allows for more complete fuel combustion, an increase in engine output power, and higher fuel efficiency for the SEM8200 Soil Compactor Series machines.• Two sets of fine filters are used for removing impurities in the fuel in order to prolong the engine maintenance interval and engine life, in addition to ensuring continuous robust output of the engine.High Performance Cooling System• The Cooling System uses Caterpillar technology.  Zoned cooling used for the steering system and transmission systems as well as enhanced cooling effectiveness for the hydraulic oil flowing through the vibration pump and motor helps prolong vibration system components service lives.•The standard cooling package guarantees that the machine can work satisfactorily up to an ambient temperature of 43 degree C, helping to prolong hydraulic components service lives as well as ensuring acceptable engine power output.• A well-located recovery bottle is conveniently provided for checking the cooling fluid level and reducing the potential for having an insufficient amount of cooling fluid by ensuring that the cooling fluid level is maintained in an acceptable range.Excellent Transmission and Powertrain Systems• The Hangzhou transmission is a standard machine configuration, which utilizes an electro-hydraulic control that allows for easy control and actuation for each of the directional and speed shifts.• The axle is fitted with a PTD Limited Slip Differential is used for controlling the amount of torque applied to the wheels under different underfoot / slipping conditions.  When one of the tires begin to slip resulting in the machine not being able to be driven forward, PTD will transfer torque automatically to the other tire helping to drive the machine out of this slip condition.  This system allows the SEM8200 Soil Compactor Series machines to be worked in various working conditions, reflecting excellent operational flexibility.Excellent Compaction Effect and Efficiency• Vibration Pump and MotorThe World Class Closed Loop Hydraulic pumps and motors used on the 8200 Series SEM SCOM ensure a completely sealed vibration Hydraulic system.  An advanced hydraulic metering unit (HMU) utilizing a large displacement allows for excellent machine turning performance highlighted by faster turns, a tighter turning radius, and greater overall steering control.• High-Pressure HosesThe high-pressure hoses sourced from the Caterpillar Wuxi factory use 24-degree cone sealing technology and the world’s most advanced crimping technology.  Subjected to 4 times rated pulse pressure, these hoses have passed an 80 million cycle fatigue test without failure, thus ensuring high reliability and durability for the machine.Convenient Maintenance and Service• The SEM SCOM compactor leverages the knowledge from Caterpillar technology to help insure the SEM8200 Soil Compactor Series machines are safe, convenient, and efficient to service and maintain.• The engine and hydraulic systems can be maintained by the large opening angle of the tilt-able engine hood.• The unique tilt-able cab design allows for convenient checking and servicing of the transmission gearbox and electrical systems.  Service points to inspect and maintain the machine can be accessed while standing on the floor or the ground.  This greatly simplifies service and maintenance activities for improved safety, convenience, and work efficiency.Comfort to Drive• The Caterpillar Industrial Design Team developed the machine appearance by using US based experts focused on providing good operator visibility and feel.  Additional features to improve operator comfort include an adjustable and rotatable seat as well as an adjustable steering column.• The cab design ensures that the cab interior is well sealed from the outside environment.  The cab utilizes isolated rubber mounts for reducing noise, shock loads, and vibration for ensuring good operator comfort during machine operations.• The seat is rotatable and can be adjusted in multiple directions and dimensions to maximize operator safety and comfort.Reliable Structure• Using Caterpillar Finite Element Analysis expertise during the structural design phase, in addition to having Caterpillar trained technicians welding the heavy fabricated structure, good stress distribution and acceptable stress levels under typical machine loads are ensured at each critical welding location.  World Class supplier rubber vibration mounts reduce stress levels transmitted by the drum through the heavy front frame structure via excellent dampening characteristics that result in high structural reliability of the machine.Good Visibility• The streamlined appearance design meets European safety standards, and allows for good front and side visibility in addition to good rear visibility by ensuring that an object, which is one meter high off the ground and one meter horizontally away from the rear bumper of the machine, is in view from an operator sitting inside the cab.  The SEM8200 Soil Compactor Series machines have excellent visibility via the shape and size of the cab.• All of the machine’s safety and operability specifications meet industry standards.Optional Configuration• Optional Configurations:  A Padfoot Shell is offered, which is applicable to work both clay and pavement compaction.  The Deluxe Seat, Radio, Air Condition, and Heater attachments improve driver comfort for improved working efficiency.  A Compaction Kit, ROPS Cab, etc., are all offered to satisfy a wide range of customer requirements.
