Safety system to prevent the collision of one or more cranes against objects, walls, shelves or between cranes of all kinds: bridge, gantry, semi-gantry, jib, etc. Avoid work accidents and damage to goods, products and mainly to your workers during maneuvers with heavy loads and the use of cranes. Avoid crash damage to your cranes.

A single team to control everything, and achieve maximum safety in maneuvers, protecting your workers, the goods handled and the facilities.

DINAKSA AC-E725 is a complete and comprehensive safety system for cranes specially designed to prevent and avoid collisions between bridges.

The AC-E725 (2-way) anti-collision system is made up of the following items:
o 2 Laser sensors
o 2 control electronics E-725
o 1 protection circuit breaker
o 1 box to house the components.

It has a reduced size and weight, which increases the integrity and reliability of the equipment when subjected to vibrations or falls.

Robust and maintenance free. It is a simple, fast and easy installation and programming system.

Reduces maintenance costs by providing greater safety by avoiding accidents due to collisions between bridges.

Technical characteristics

Option to choose: Range of 10 or 30 meters

Equipped with a single microprocessor, it has an 8-digit LCD display, 3 buttons for programming and 5 high-luminosity LEDs that act as status indicators (activation of configured outputs).

The equipment has three programmable relays (0.2m to 10m or 0.2 to 30 meters) that are used as distance limits:
o Relay 1: Cuts fast speeds
o Relay 2: Cuts the movement
o Relay 3: Reserve

These three relays can act instantaneously or timed, both in activation and deactivation, as required by the customer.

The electronics have fault detection, if the laser sensor has a defect or one of the cables breaks.
