Double Girder Grab Bridge Crane for Lifting Scrap in Steel Mill
Factory
Bridge cranes are high-capacity FEM class heavy duty cranes that
can meet customer demands in iron and heavy industrial plants or
energy sectors. These cranes are specially designed for customer
satisfaction and they are designed with high engineering
techniques.
Bridge cranes use its experience in process cranes to supply process cranes
especially for overseas steelworks, energy and heavy industrial
enterprises. We are serving the world's leading companies for the
pot cranes, billet cranes (cranes with travers, rotating cranes),
scrap cranes with grab and magnetized cranes.
Bridge cranes engineering, the young and experienced engineering department,
provides a competitive advantage with its human resources and
production times, and strives to bring the process crane production
quality to the top.
Brief introduction:
Rigid Light Crane System provides an ergonomic and cost effective
solution to conventional overhead crane systems particularly when
there is a height and space restriction. Versatile and reliable
overhead handling can be achieved for a variety of applications
using the modular design. The robust design of our components and
the high standard of manufacturing guarantees long life with the
minimum of maintenance. Our program range consists of sliding door
fittings, overhead conveyor systems, festoon systems, fall arrest
systems and light cranes.
General descrption:
Two girders are simply stronger than one, making double girder
traveling cranes the ideal solution for the area coverage handling
of heavy loads up to 32/5t. Like all factory cranes, these units
are available with a number of main girder connection versions to
best suit new or existing buildings and the best in functionality,
versatility and convenience. double girder cranes feature welded
box beams. All the sections used for main girders and end girders
are computer-optimized for high performance and low weight,
benefits that pay in terms of strength and cost efficiency.
Mechanical feature:
Double welding box girder, DIN/FEM standard deflection.
Material Fe37 or Fe52.
Whole length CNC cutting for complete web plate, high deflection
accuracy.
Trolley rail is high strength flat steel bar (hot rolled ,16Mn).
High quality automatic welding and NDT inspection.
Shot-blasting Sa2.5 for complete girder after welding, stress
release.
Epoxy zinc rich high quality painting, 2x2 with 140μm.
10.9 class High tension bolts mounting between girder and legs,
life time safety connection.
Compacted gear motor driving, continuously variable control, harden
gear, safety disc brake.
High protection class IP55, F class, 40% ED.
Double flange or flat wheels, anti-friction bearings, cellular
buffers, derailment protectors.
Full-length service platform along the crane bridge is
supplied,where it is equipment with protective hand railing and toe
strips.
Electrification and outfitting:
Conductor power supply.
Phase control guard opens the main contacts in case of phase
failure.
All hoist and crane movements are independent and can be run
simultaneously.
Contacts meet crane applications, rated for severe vibration.
The control panels are finished to withstand corrosion, IP55.
Heavy duty plug head.
The components are positioned in a maintenance friendly way, and
the whole layout provides good protection against accidental
contact.
The integrated plug type fixed cables with plastic insulation are
intended for crane usage.
Cables are coded either with numbers, colors or tags for easy
identification.
The flat cables used for festoons are PVC insulated flexible flat
cables rated for 450/750V, specially designed for cranes, hoists.
Festoon cables are suspended on cable saddles, fixed to cable
trolleys, running in a galvanized C-track, which is connected to
the main girder with bolted or welded support brackets.
Application:
It is specially fit to the areas of dense equipments,
transportation in short distance, telescopic beam crane system and
high work frequency.
It is vastly used in the following industries, aerospace industry,
Auto-mobile, ship building, electronic assembly, food-production,
mechanical production, warehouse, etc.
