Application The AWC Dynamic (In-Motion) Axle Weighbridge is designed to be an economical and convenient solution for measuring the weight of moving trucks.The AWC JUMBO Dynamic (In-Motion) Axle Weighbridge is a system consisting of individual weighing platforms which measure the load on each wheel of a dumper truck dynamically or statically. Its modular design enables any possible truck axle configuration or model of mining dumper truck. A large external LED display is available for quick and easy viewing of the weights. A traffic light can be used with the large display to tell the driver when to move on and off the weighbridge.

Main Features

• Capacities up to 200T.
• Simple operation.
• Save time by weighing vehicles on the move.

• One weighing platform of size 3 M X 0.75 M or two weighing platforms of size 1.2 M X 0.8 M or 3 M X 2.4 M.
• Dynamic ( in motion ) weighing.
• Travel speed up to 5 km / hr.
• Weighing up to 24 tons per axle. Accuracy in dynamic weighing +/- 1% of FSR.
• Under and over load selectable by user with alarm facility.
• ARM CPU system with high arithmetic speed.
• 24-bit high-precision and high-speed sigma-delta conversion module with 130, 000 internal code [AD value] used and 200 Hz sampling frequency.
• EMC design with high anti-jamming capability, suitable for industrial environment.
• Menu & shortcut mode operation with key tone.
• Auto-locking, key-locking, key-unlocking, digital setting , calibration and I/O testing functions.
• 1 optional and definable analog signal output (4-20 mA ).
• 3 normally open switch inputs [DI] and 5 normally open relay switch outputs [DO].
• Support industry configuration software.
• The historical axle weighing records can be queried and printed.
• The present axle weighing record can be printed automatically and manually.
• 2 optional communication ports for linking to PC/PLC, remote display and operation terminal, serial printer, wireless module, etc.
• Special filtering algorithm for ensuring weighing stability and accuracy when there is strong vibration on the load receptor, and rapid response capability when the weight signal changes.
• With the multitasking mode, the weighing and control process will not be interrupted by parameter setting and the other operations.
• Once the internal temperature exceeds 45C, the cooling fan of weighing controller will work automatically to avoid overheating under the high ambient temperature.
• Optional RFID reader with Tags and traffic lights.

Application The AMSTEL Torpedo Weighing Rail Scale is a pit less state of the art static weighing scale for hot torpedo cars. High precision , hightemperature load cells are installed between the existing rail clamps and the existing wooden or concrete sleepers. They reliably transmit all vertical forces applied by the torpedo car wheels , with a high degree of accuracy and repeatability. The weighing system is installed without a foundation and can be installed without additional effort during a normal track maintenance period.A PC is used to record and process the weights including supplementary data Load cells determine the weight of the pig iron that is leaving the blast furnace for the steel plant. The torpedo weight can be measured.

• as a static weighing system at the tapping position of the blast furnace.
• by weighing half of the entire torpedo car.

Features

• Static weighing of hot torpedo cars.
• High temperature load cells for operating temperatures up to + 200C.
• Load cell design based on existing rails.
• Precise determination of hot metal output.
• Pitless and gap free design.
• Large measuring area.
• High accuracy.
• Installation without foundation.
• Capacities up to 800 tons.

he Ladle Weighbridge is designed to weigh hot ladles and slag pots. The weighbridge utilizes DWB series double shear beam high temperature load cells and cable that can withstand temperatures of over 250C . These load cells have self- aligning bearing assemblies and flexure plate checking system.

Specifications

• Digital Weighbridge
• Double-ended shear beam load cells .
• High temperature load cells and cable
• Floating load cell bearing assemblies
• Flexure plate checking system
• Self aligning system
• Digital indicator with printer, computer and wireless CellModem interface

The Crane Boy is a crane safety overload limiter integrating independent set points and built in display . Each of them activate a relay , specially conceived , dedicated and configured to hoists and crane load applications.

Main Functions

• 3 point overload alarm

• Automatic and manual calibration

• Parameter setup through menu

• Programmable digital filtering

• Self inspection.

Application:
The high temperature load cells have a compensated working temperature range of +200C and a limit temperature range of +250C. They are manufactured using special strain gauges, adhesive , wiring and teflon cable to withstand the high temperature. This makes then suitable for weighing systems for tundish , ladle transfer cars , ladle turrets , ladle cranes , foundry cranes etc and other applications that are subject to intense heat.
Load cells can also be offered having the same body style and capacities as ABB and Schenck load cells replacing capacities from 10MT to 160MT.
