FOR OVERHEAD CRANES & OTHER GUIDED MATERIAL HANDLING
EQUIPMENT
Laser-Guard is an advanced
laser-based system that offers distance control and collision prevention for cranes or
other guided machinery. It consists of a Class 1 laser transmitter/receiver, special
universal mount and a reflective target.
 A typical application would be to mount the laser transmitter/receiver on the
bridge of a crane and mount the target on the structure to be avoided.
 Laser-Guard will sense
and measure the distance of a crane moving at up to 800 fpm, slowing it in one, two or
three user-adjustable stages (to eliminate load swing), and bringing it to a halt. It is
self-monitoring and includes contacts for alarms or shutdown.
Safe and economical, Laser-Guard cannot be jammed by RF interference, unlike radar
or other radio-based anti-collision systems
System features include:
Safe Class 1 Laser Rating
Range: 5 to 150 feet

Laser Anti-Collision Specifications
Power requirements: 120/240 vAC, 47-60 Hz, 180-260vDC, 10-12 vDC, special voltages on
request.
Range 5-150 feet with 3
independently adjustable outputs or set points: 5 - 40 ft, 40 - 70 ft, 50 - 100 ft. An
optional relay interface panel provides a timed bypass on activation of the third set
point, allowing operation close to a wall or another crane. Each set point may be adjusted
within its range, with an accuracy of ± 10%.
Temperature: -30 to +70
degrees C
Outputs: Standard single pole,
normally open or normally closed relays are used. Contact rating is 5 amps, 110 vAC, 60 Hz
resistive. Note: If any contactors to be controlled by this device exceed this rating,
interposing relays must be installed
Optional Interface Panels:
Additional interface panels are available for 480 vAC and 250 vDC.
Enclosure: Standard system
enclosure is NEMA 12; other enclosures available on request.
Laser: Class 1
Laser-Guard has evolved from TELTEC, the unique
medium-range anti-collision system in use since 1976. TELTEC is widely used throughout the
world on cab, pendant and radio-operated cranes to prevent collisions over a range of 10
to 100 feet.
Users in a wide variety of industries have already improved employee safety,
reduced product liability, and avoided damage to machinery. In the same way that TELTEC
has shown itself to be low-cost insurance, Laser Guard will continue to safeguard valuable
equipment even more effectively.
