| Crane Weighing System |
 |
| Conventional Crane weighing
systems are battery operated and suspended from the crane
hook for sensing the weight. We provide fixed type crane
weighers where the electronics is mounted permanently
on top of the crane and operated using the crane power
supply. The equalising pulley is supported by load cells
using suitable mounting assembly. |
| The load cell mounting assembly
is designed to prevent overload / tranverse loading of
the load cell as well as lift-off protection. As the operating
temperature is high, suitable temperature protection is
also provided. |
| The Load cell Signal Conditioner
in an IP 65 enclosure is also fitted on the CROSS TRAVEL.
The 4-20 mA current signal corresponding to the load is
taken to the Main control Panel via a shielded cable. |
| The Digital Weight Indicator
is mounted in a control panel together with power conditioners
/ battery backup. The control panel is fixed on the LONG
TRAVEL of the crane. It communicates with the Jumbo Display
through RS 485 Serial Interface. The Jumbo Display shall
have visibility over a distance of 75 meters and above.
|
| A rope weight compensation
unit is optional to compensate for any variation in weight
during up and down movement of the crane. A pendant display
for the crane operator with ZERO & TARE push buttons
is also optional. |
| This type of Crane weighing
systems are ideally suited for foundries where molten
metal is handled. The effect of high temperature is minimized
in this system as the electronics and the sensor are installed
at a distance from the material handled. |
