Product Description

Product Description

* The electronically controlled power shift gearbox of Hangge has high reliability and durability. Optimized design of transmission ratio, more matching the vibration frequency of the light wheel, to achieve better compaction effect and higher compaction efficiency

* The handle controls forward and backward, button-type increase and decrease gears; the clutch pedal can control the engine to automatically decelerate, and the gear can be shifted without adjusting the throttle. The operation is simple and convenient

* Specially equipped with a ramp switch, which can release the automatic deceleration function of the engine controlled by the clutch pedal to ensure continuous sufficient power when the roller goes uphill.

* PTD progressive split-torque differential to ensure the driving force of the machine under harsh ground conditions and better passability of the whole machine (optional)

* The three-level fault alarm system can accurately judge the severity of the fault at the fault point according to the alarm level

* During use, real-time detection of abnormal conditions of multiple systems to prevent failures

* Vibration frequency meter displays the compaction frequency in real time, monitors the compaction effect and possible frequency drop phenomenon; through the frequency change, timely judge the possible failure of the hydraulic system

* 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 vibration, smooth amplitude switching, reducing the impact on the vibration motor and prolonging the lifespan'

* Fully sealed eccentric wheel keeps the lubricating oil clean and pollution-free and prolongs the life of the bearing. Maintenance-free within 2 years/2000 hours, reducing maintenance costs
