Performance Characteristics
- AHT4000/6000/8500 are suitable for the construction of concrete road, airport, plaza, and also for high-speed railway support layer.
- Simultaneous operations of hydraulic-activity supporting course, scraping, vibrating, tamping and extruding at the same time.
- Full hydraulic independent drive, micro-computer with display and self-diagnostic capability.
- Auto levelling and tracing systems to ensure paving flatness, straightness and smoothness at road bends.
- Ergonomically designed with smart controls for operational comfort and ease.
- Imported key components to ensure machine reliability and prolong service life of the paver.
Features
- Engine: Volvo / Cummins water-cooled engine, powerful, high-torque reservation, low fuel consumption, emission in conformity with Europe environment.
- Vibration Device: Super-high frequency, strong vibration, high density of top-side paving
- Auto Levelling System: Auto levelling and tracing systems ensures paving surface flatness and road straightness.
- Scraping Plate: Controlled through two hydraulic cylinders to control concrete quantity incoming to shaping-template, which could go up & down wholly or up & down independently at either lh or rh.
- Travelling System: Two hydraulic-drive crawlers and microcomputer control ensure pre-set constant speed, correct straight-line running and smooth steering at bends.
- Centralized Lubrication: Centralized lubrication can auto. Charge lubrication grease to high-temperature and motive components, lengthen wear-out period effectively, greatly improve reliability of tamper and feeding.
