Road maintenance that requires operational reliability
4/4/2023
This year's winter in Sweden has had a varied weather, from 52°F in the southern parts of the country and -36°F in the north. With bare ground in many places in December, while there was half a meter of snow along the Baltic coastline in three days.
With the changes in weather, there were major challenges for road maintenance on the Swedish roads. From large amounts of snow that must be ploughed away to later when wet roads freeze and need to be sanded and salted. In order for the trucks to have the possibility to be flexible for many different types of work, many build combination trucks with several functions. It expands the truck's range of use to perform a variety of road maintenance tasks.
Hydraulic plough equipment is required to remove the snow efficiently and quickly during heavy downfall, in many cases with more than one plough. Equipment for spreading sand and salt with a large capacity is also required to cover long stretches of road.
Our hydraulic pumps and motors have a long experience of being tested in these though and rapidly changing weather conditions, which is important for operational reliability.
Sunfab offers several options to suit your specific system needs
We offer a wide range of hydraulic pumps ranging from 0.77-7.93 cu in/rev. The pumps offer single, double or variable flows with working pressures up to 6527 psi as well as different standards such as DIN, ISO and SAE.
The Sunfab Dual Flow Pump is ideal for vehicles that require two different flow rates. The range of fixed displacement dual flow pumps SCPD and SLPD comprises 10 different sizes from 1.24/1.24 up to 4.58/4.58 cu in/rev. The SCPD dual flow pumps are of bent-axis design, the SLPD pumps are of inline design, both very effective and powerful. Sunfabs dual flow pump is ideal for vehicles which require two different flows.
Sunfab also offer variable pumps with a displacement of 3.81, 5.32, 6.74 and 7.93 cu in/rev. A working pressure of up to 450 bar, and flexibility via different types of regulators and tandem assembly. This enables the use of this type of pump in almost all applications where a variable oil flow is required.
Sunfab’s hydraulic motors are available in SAE, ISO and DIN-standard as well as with cartridge flange. Displacements range of 0.59-7.93 cu in/rev with a large number of choices regarding shafts, mounting flanges and connections. Sunfab’s motors are known for being able to handle high speeds and high working pressures, up to 5800 psi, and power outputs of up to 285 kW.
