- • Dumping by cylinders.
- • Supported on rubber pads.
- • Effective unloading of material.
Flotation System
This system releases the weight of the screed so that it "floats" over the asphalt concrete with the lowest angle of attack as possible, favoring the perfect paved surface finish as well as improving the traction and the response time to changing the thickness applied.

With the floating system, the paving thickness is adjusted by the inclination of the screed in relation to the ground (angle of attack), increasing or reducing the layer of pavement.
- Main advantages:
- • Better surface finish.
- • Greater uniformity of the pavement thickness.
- • Contributes to a greater pre-compaction level.
- • Makes it possible to work with all paving thicknesses, from 15 mm (19/32") up to 300 mm (11.13/16").
- • Provides the option of the equipment to adjust to different types of mixes, especially low-density mixes such as soil-cement.
Dual Concept System
- • This exclusive system makes it possible to change the traction system from tires to crawlers, or vice-versa, in only two days.
- • The chassis of the equipment is one and adaptable, which makes it possible to receive both traction by crawlers and traction by wheels.
- •Its single hydraulic system simply requires the substitution of the positive traction, installed on the machines with tires, for a differential flow valve, installed on the machines with crawlers.
- • The steering system needs the steering wheel installed on the machines with tires to be replaced for a hydraulic joystick installed on the machines with crawlers.
- • The tire traction system, made up of rear tires and front dual wheels, is substituted for trucks or vice-versa.
Automatic Systems of Operation
- • Preset System - interconnects all of the essential functions of the equipment, ensuring maximum paving quality.
- • Screw conveyor system linked to the floatation of the screed - makes sure that the floatation system is always on when the machine is in operation.
- • The signals of the electronic grading system are blocked when the machine is in neutral, awaiting more mix or on standby.
- • The parking brake is automatically actuated when the equipment is put in neutral.
