9t 13m/6mSingle Girder Underhung Overhead Crane for Low Height
WorkshopProduct DescriptionOpportunities: Underhung overhead or
bridge cranes are a good choice for factories and warehouse
facilities that want to free floor space of obstructions and
improve safety and productivity. Underhung cranes-sometimes
referred to as under-running cranes-do not require supportive floor
columns. This is because they typically ride on the lower flange of
a runway beam suspended from the facility roof or rafters.By
optimizing end approaches, underhung overhead cranes make the most
of facility space. That is, they allow the hoist to get closer to
the end truck or end of the runway than is possible with a
top-running crane. The underhung configuration also maximizes the
bridge end approach, or how close the bridge girder can get to the
wall or the end of the runway.Considerations: As their beams
are suspended from building roofs, underhung overhead cranes are
limited in lifting capacity-usually 10 tons or less. Before
choosing an underhung crane you should have the structural strength
of your facility's roof evaluated. Supporting beams can be added to
permit increased load capacity.

and Manufacturing
Feature-----------------------------------------------------------------Design
Code: NANTE's Single Girder Low
headroom overhead crane follows the design code of FEM, CMAA, ISO
EN, BS, GB standard. Low headroom Hoist:
C-shaped design, compact structure, smooth operation,
accurate positioning, high Safety reliability, and
Maintenance-friendly.Girder: Compact
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 Galvanized C
track system with flexible flat cable, one line for hoist power and
signal transmission, one line for the pendent control trolley
movement. No-welding claw is design for the brackets of the festoon
system fixing. Safety Protection Functions:
NANTE single girder overhead crane include a lot of
protection functions, like Overheat protection for the lifting,
load cell type overload limit switch, up&down position limit
switch, cross limit switch for the cross travel and long travel.
Phase sequence relay, and other optional functions, like crane
monitoring system, LED load displayer. Controls:
NANTE single girder overhead crane can offer
both options of remote control and pendent control.Anti-corrosive
Treatment: Shoot Blasting follow
ISO8501-1 SA2.5 class, roughness follow ISO 8503 G class, clearness
follow 8502-3 Level II. Use top brand's Rich zinc epoxy painting
for the prime, middle layer coating. Use polyurethane topcoat for
the finished layer coating. All NANTE painters are trained or
inspected by NACE or FROSIO level II Inspector.Product
