The document describes an anti-crane collision system from Infra Systems that uses infrared photoelectric sensors to detect when two overhead cranes on the same rail get too close and stop the moving crane to prevent collisions. The system includes a laser alignment tool to properly align the sensor and reflector units and allows adjusting the detection range as a single or double set point for alarms or stopping.

1. Anti Crane Collision System
Is Infra Systems
Infra - red Photoelectric Sensors
Infra systems Offers Anti Crane Collision system for two over head cranes on the same rail. With these units, the two
cranes on the same rail will never collide with each other & thus the damage caused due to collision can be saved. Laser
alignment tool is provided for perfect alignment of Sensor unit and reflector. The reflected beam will be picked up by the
receiver when both the cranes come closer. When the two cranes come within the range, the moving crane will be stopped
immediately. This range can be adjusted for single set point, as required. For two set points, one can be adjusted to get an
alarm at required distance and another can be set stop the crane at required distance.
