ATO-LCST-TJL-7 Tension Load Cell for Crane, 2 ton/5 ton/30 ton/50 ton to 70 ton
After purchasing one ATO load cell, you can buy a special digital panel meter to obtain readings directly, or buy a transmitter to output standard signal to PLC, DCS and other systems. Customized output signal of load cell transmitter is 0-5V, 0-10V, or 4-20mA.
Note: The load cell cannot be connected to both the transmitter and the controller at the same time — only one can be selected.
Tension and compression load cells have capacity range from 2 ton, 3 ton, 5 ton, 7 ton, 10 ton, 20 ton, 30 ton, 50 ton, 70 ton to 100 ton. Strain gauge load cell capacity can be customized according to customer requirements.

Tips: How does a Tension Load Cell improve crane operation and maintenance?
Tension Load Cells contribute significantly to both crane operation and maintenance in the following ways:
- Enhanced Crane Operation: By providing real-time feedback on the load being lifted, operators can ensure that cranes are not overloaded, which reduces the risk of mechanical failure. Additionally, load cells can be integrated into a crane’s control system to adjust lifting speeds or stop operations if an overload is detected, providing automatic protection.
- Improved Maintenance Practices: With accurate load measurements, maintenance teams can track the crane’s usage more precisely. For instance, if a load cell reports frequent overloads, this could indicate that the crane’s mechanical components are under excessive strain, prompting early intervention before damage occurs.
- Preventive Maintenance: By consistently monitoring the loads lifted, maintenance staff can anticipate when the crane will require servicing. This helps schedule preventive maintenance tasks, ensuring that the crane remains in optimal working condition, reducing unexpected downtime and repair costs.
