Product Description

Vibration system

• Pod Vibration System for better performance and reliability
• The movable steel ball is enclosed inside the eccentric wheel, and the position of the center of gravity is adjusted through the direction of rotation to achieve the purpose of adjusting the amplitude. Stable start-up, smooth amplitude switching, reducing the impact on the vibration motor and prolonging the service life
• Fully sealed eccentric wheel, no pollution, prolong bearing life. Maintenance-free within 2 years/2000 hours, reducing maintenance costs

Cooling system

Independent four-module cooling system to ensure 24-hour continuous operation

• Suction fan, fresh low-temperature air enters from the tail of the whole machine, and passes through the radiator to the engine to ensure the cooling effect
• Optional high-temperature cooling system, which can work at an ambient temperature of 50 degrees

Equipped with an expansion tank, which reduces the loss of coolant and prolongs the period of coolant replenishment
 

Hydraulic system

• Closed hydraulic circuit, hydraulic transmission efficiency is 20% higher than that of open circuit
• Pumps and motors of world-renowned brands form a closed circulation system, which reduces oil damage
• Less chance of contamination, higher system cleanliness, prolonging the service life of the hydraulic system
• Vibration system with higher pressure and less energy loss
• The pipeline layout is simpler and the maintenance space is increased
• It only needs to be equipped with a small volume hydraulic oil tank, which reduces maintenance costs
• The pressure measuring joints are all designed on the vibrating pump, which improves the service life of the pressure measuring joints

Electronically controlled engine

• SEM518/520 adopts WP6G175E301 (129kW), SEM522 adopts WP6G190E301 (140kW)
• Emissions meet the National Three Standards

Transmission system

• The shifting operation of the electronically controlled transmission is easier, reducing fatigue and improving production efficiency
• The whole machine is operated smoothly, with high reliability and low failure rate

• Eaton Proportional Torque Limited-Slip Differential, better passability of the whole machine, and gradeability up to 34%
• Optimize the transmission ratio and increase the working speed of gear I

Dash board

• The three-level fault alarm system can accurately judge the severity of the fault point according to the alarm level
• During use, detect abnormalities of multiple systems in real time to prevent failures
• The vibration frequency meter displays the compaction frequency in real time, monitors the compaction effect and possible frequency drop phenomenon; judges the possible failure of the hydraulic system in time through the change of frequency

Cab

The forward-tilting cab of a well-known brand in the industry is more convenient for inspection and maintenance of hydraulic pumps, gearboxes, hydraulic pipelines and circuit systems, etc.

• Standard manual flip cab
• Optional hydraulic flip cab
• Rearrange the panel, the operation switch is more user-friendly
• Knob-type electronic throttle, more flexible and more reliable
