Description

The sprayer for bituminous emulsion of the Bruno Group US line is one of the machines best appreciated on the domestic and international market since it has an excellent price – performance ratio and, even if it is a simple and low-cost machine, it has all that is necessary to enable the operator to distribute the emulsion uniformly on the road bed before laying asphalt.

The US line tank sprayer are designed to be mounted even on small-size trucks having a low load capacity.

The capacity of US tank sprayers for bituminous emulsion is ranging from 1000 lt to 5000 lt.

The emulsion is loaded into the tank at the bituminous conglomerate plant through a flexible pipe in the upper hatch and kept hot (at a temperature ranging from 40°C to 60°C) thanks to a burner operating at 120V DC; heating is adjustable through a digital display and the inner temperature is kept constant.

The emulsion is conveyed to the site and sprayed onto the asphalt through the spray bar by using an additional manual gun that can reach the most difficult points of the road surface.

Spraying occurs through a special emulsion pump with a heat storage tank (heated by the engine exhaust gas) connected with a hydraulic engine operated by a lever distributor, which enables the operator to work even at extremely low temperatures and with any kind of emulsion.

A vertically mobile bar operated by 2 hydraulic cylinders driven by a lever distributor will be moved up and down; a standard bar will open manually, but it is possible to install a bar opening automatically when driven by two hydraulic cylinders.

At the end of work, it will be necessary first to clean the machine by using compressed air drawn from the truck (air purges the emulsion conduits) and then to operate the gas oil washing device for a complete clean cycle.
