First, performance characteristics

1. Efficient paving:

Conveyor passage

The optimized design of the conveyor channel can improve the material throughput, so that the speed of paver discharge is as high as 1000t/h.

hopper capacity

15 tons large capacity hopper can support uninterrupted material transportation over a long period of time, as well as paving operation of paving layer. According to the characteristics of Chinese truck unloading truck fully extended design provides ample space, can effectively improve the truck unloading speed, so as to achieve uninterrupted paver. The paving thickness is up to 400mm, and it can provide excellent pre compaction and good quality paving effect.

Large size screw divider

Accurately control the material entering the spiral distributor channel to ensure the stable material quantity before the ironing plate. The screw feeder with diameter of 420mm can provide stable and uniform material distribution, and ensure excellent paving quality.

2, Volvo extraordinary power

Intelligent energy saving mode

Shop without occasion in the operation to the full power of the stalls, the operator can spread machine management system in electronic booth (EPM II) on the choice of "intelligent energy saving mode, the engine automatically reduce the speed, thus can reduce fuel consumption by 30%, while significantly reducing engine noise. 170KW Volvo 7 liter displacement engine is a perfect combination of strong power and low fuel consumption.

Large ground

The large ground track, the weight distribution can be combined with ideal, strong engine power is efficiently converted into walking traction, the paver under various operating conditions which can achieve high quality paving.

Balanced design

The weight of the machine is evenly distributed on the large track ground, so that the machine has the ideal traction force, paving stability and controllability. The matching of paver weight, traction device and engine power can provide ideal paving performance output.

3, the best quality

Feed

According to the characteristics of Volvo China lorry, the paver were specially designed. Before the push roll forward extension of 200mm, in order to prevent the truck body and collision between the paving machine hopper. The front roller support has horizontal swing function, which can effectively compensate the slight deviation of the truck wheel when the truck unloads the material into the hopper.

Sealed protective bearing

In the strict operating environment of conveyor system, the design of conveyor and screw feeder system with durable bearing can effectively protect the bearing, thus prolonging the service life and normal operation time of the machine.

Harsh condition protection

For extremely heavy work conditions, Volvo provides two sets of matching kits to enhance the wear and tear protection performance of the delivery system. Wear resistant parts can be pre installed to the machine or from the local Volvo dealer.

Caterpillar support wheel

The two supporting wheels fix the rail chain securely and securely to prevent it from sliding on the rack so as to enhance the durability and prolong the service life of the components.

Track automatic tensioning device

The hydraulic track tensioning control system enables the track to maintain a constant tension, so as to ensure smooth operation and high quality paving. In addition, the system also helps to reduce the wear of track parts and prolong the normal running time of the machine.

4. High performance paving

Double rammer

The double rammer technique used in the screed can obtain high pre compaction when the cement stabilized soil material is paved - which is very important when the thickness of the paving layer is thicker. This device can help reduce the number of roller compaction, not only save construction time, but also reduce construction costs.

Proportional steering control

Both straight and curve paving, electric hydraulic system can provide smooth, precise steering control.

Adjustable screw distributor

The whole height of the screw distributor can be adjusted by manual or hydraulic, and the transverse conveying of the material in the paver is adjusted. As a result, the material can be evenly distributed to the front of the screed, which is essential for obtaining high quality paving.

Constant feed rate

Increase the hopper capacity with the size and speed of the conveyor and the speed of the screw feeder, to achieve greater material throughput, to ensure the smooth flow of material flow to the screed.

5, Volvo, the normal operation of the machine to protect the time

Interchangeable ECU

To facilitate maintenance, the three electronic control units (ECU) of the paver can be interchanged. Each ECU can control all the functions of the paver.

The split traction arm can easily remove the ironing plate from the split joint so as to quickly remove the ironing device from the traction device. The system consists of an adjustable shim, which is convenient and flexible to adjust the screed paving thickness.

Hydraulic oil filter

Efficient single hydraulic oil filter design provides up to 3000 hours of maintenance intervals. This reduces the frequency of maintenance, saves maintenance costs, and reduces the working hours of the machine that the machine uses when the oil is removed from the shutdown.

Central lubrication system

The drive shaft of the conveyor and the screw divider support bearing assembly are centralized lubricated by the central lubrication system. The lubrication system can continuously lubricate the lubricating points, reduce the daily maintenance strength and prolong the service life of the bearings.
