Design and low weight, use Q355B steel material(ISO EN S355, DIN
ST52, ASTM A 572 Grade 50), welding specification follows ISO
15614, AWS D14.1, deflection can from 1/700 ~ 1/1000, MT or PT is
requested for Fillet welding and UT is requested for joint welding.
End Carriage: Direct Driving design with
high transmission efficiency. Using hollow tube for the steel
housing. Wheel material is alloy steel with proper heat treatment
which is more stable and durable. Gear
Motor: Worldwide top brand gear motor to
make sure the quality, IP55, F insulation class, overheat
protection, manual release bar, and equipped with electro-magnetic
brake.Control Panel: Follow IEC
standard, IP55 powder coating high quality enclosure, socket
plug-in for easy connection, DIN standard terminal, international
brand for the inverter, MCB, Contact and electrical devices on the
panelFestoon System: Double line
