BCS VOLCAN SDT DS/RS
The SDT are the short-wheelbase with odd wheels version of the Volcan tractors. This version combines the basic characteristics of conventional tractors with those of tractors with “even” wheels of the same height, obtaining machines extremely compact with limited steering radius and an height from the ground which let them to be used in vineyards and orchards.
The Volcan SDT in Dualsteer® version allow steering angles of 70°. The qualities of this version are enhanced not only by the extreme manoeuvrability and functional capacity of the machine, but also by the uses in transversal slopes, a typical feature of the crawler tractors.
The low driving position and the exclusive structure of the cabs make this machines truly unique on the market: the Compact version of the cab is just 169 cm high, priceless for working under branches. it is the only compact cab homologated without a roll bar, proof of the quality of the product and the excellent work of the BCS technicians.
Engine
Three VM engines for the Volcan SDT series, able to get the power out of every drop of fuel.
VM D753 IE3 2.2 litre, in-line, 3-cylinder turbo diesel. Producing 70 HP at 2,300 rpm thanks to the intercooler.
VM D754 TE3 3 litre, in-line, 4 cylinder, turbo diesel. Developing 79 HP at 2,300 rpm.
VM D754 IE3 3 litre, in-line, 4 cylinder, turbo diesel. Producing 91 HP at 2,300 rpm thanks to the intercooler.
For these models, VM has developed the new EGR System placed inside the engine. The system recycles the exhaust gases which, opportunely mixed, return to the combustion chamber, drastically reducing the emissions of nitrogen oxide (NOx) and fuel consumption.
Transmission
FLUID MECHANICAL GEAR
The performance of an engine would be nothing without the best transmission. The new Sincro 32-speed transmission with synchronized reverser and helical gears offers the very best performance, improving the comfort and drivability of the vehicles. Designed to avoid gear overlaps in the four ranges, you will always fi nd just the right gear for the job.
4WD WITH TRACTION DISENGAGEMENT
The four wheel drive can be disengaged on the front axle with an electro-hydraulic control. This allows rational movement both on steep slopes and uneven ground, as well as being the best solution for fast road use.
A UNIQUE TRANSMISSION SYSTEM
The new transmission comes with the OS-Frame which, with one single transmission shaft and one central joint, guarantees the maximum mechanical performance. The joint in the middle of the vehicles lets the front axle oscillate by up to 15° with respect to the rear, for excellent stability on slopes.
PRO ACT-SYSTEM CLUTCH
The LONG-LIFE clutch is a multiple disc hydraulic clutch running in an oil bath, and no adjustment or maintenance is required. Light and progressive, its performance is guaranteed by the PRO-ACT System, a system that lets the driver use the clutch in a comfortable and rational way, thanks to the parallelogram clutch pedal with a progressive action that takes up any play.
THE VERY BEST IN BRAKES AND MORE
Four multiple disc brakes running in an oil bath of the very latest generation with hydrostatic control guarantee perfect adherence to the ground, for safe braking in any conditions. The hydrostatic control acts as a brake force distributor, sending the same pressure to the 4 wheels simultaneously when the pedal is pressed.
The Volcan SDT can be also suited with the exclusive independent BRAKE-OFF parking brake system, which is automatically activated when the engine is turned off. When the engine is running however, it is controlled by a practical button on the dashboard.
Driver
When we designed the cabs on the Volcan SDT, we set out standards high, higher than anyone else had done before: the result is cabins meticulously studied and realised to guarantee the maximum comfort with the most pleasant living conditions. On the Comfort version the large windows optimize the drivers environment.
The Compact series has a particular structure that keeps the height of the vehicle down to just 169 cm for working under branches. Furthermore, this is the only homologated cab on the market with these characteristics that doesnt have a roll bar.
Despite the compact dimensions, the Joy-Stick for controlling the hydraulics is also inside the cab, a plus for the Volcan with respect to competitors.
All the Volcan SDT cabs are pressurised and have the suspension completely independent from the roll bar of the tractor. The air conditioning and heating are controlled by an efficient plant which is car-type integrated in the front control console.
Hydraulic System
In a specialized tractor, the performance of the hydraulics is fundamental. The Volcan SDT has a double hydraulic circuit with independent pumps and a heat exchanger: – the first pump, with capacity – 31 L/min, is dedicated to the power steering – the second pump, with capacity – 31 L/min (optional – 49 L/min), is dedicated to the lift and to the distributors with hydraulic pressure 180 bar.
There are up to 8 hydraulic outlets at the rear of the machines to connect equipment that requires high-capacity hydraulic supply, often used in vineyard cultivations. To meet the requirements of our most demanding customers, we have studied electronically controlled Joy-Sticks, which control not only the hydraulics (9 front distributors and 5 rear) but also the lifts.
The rear lifts are strong and have practical and versatile multipurpose linkages, suitable for all kinds of equipment on the market. On request the tractors can be fitted with a controlled force and position system, for all equipment that requires the same.
The Volcan SDT can also be equipped with a practical front lift, essential for combined use, supplied with four hydraulic outlets.
