No Limit

Load limiters for hydraulic boom cranes, lattice-boom cranes, mini cranes

The instrument covers the supervisory function, which plays an important role in ensuring that all material handling operations take place without the risk of the machine tipping over, limiting its load capacity: this ensures the operator’s safety and avoids costly damage to the machine, equipment and materials being handled.
The instrument’s control software is a powerful Load Limiter, Arm Angle Limiter, Scheduled Maintenance, and a simple Weighing system with load cell is available as an option. The SW licence option relating to WEIGHING is particularly interesting and appreciated by those in the industry. The systems are designed in accordance with the Machinery Directive 2006/42/EC with reference to 13849-1 cat. C/D.

The MAINTENANCE LIMITS control page provides a periodic maintenance schedule for the machine on which the system is installed.
Contains a series of set limit values and corresponding statuses, which indicate whether the machine needs to be replaced
.
Object to be replaced when the corresponding “STATUS” changes from “OK” to “LIMIT“.
LIMITHOURS ” of the object to be replaced is equal to or less than the value of the motor operating hours totaliser.
