LMC™ Crane Controls - Retrofits & New Installation

Bridge & Trolley Motor Controls up to 200HP

Solid-State IGBT Control

Series-wound DC motors delivers high torque at startup, adjustable speed points and acceleration / deceleration ramps, electric braking and elimination of all contactor problems

Easy Retrofit Installations

Connect existing power cables
Connect existing motor cables
Connect existing brake cables
Connect existing operator controls
Fine-tune pre-set acceleration ramps, speed points and braking

Save Energy Costs

Motor energy consumption reduced up to 50% plus torque boost at startup is 7 amps in the motor for every 1 amp drawn from the power source - motors work easier and last longer

Save Maintenance Costs

Solid-state construction, no wear components plus microprocessor control of contactors means contactors never make or break a load

LMC Crane Control Technology Eliminates problems caused by

Brownouts and discontinuity of the power supply
Substantial negative ring of supply voltages
Positive-going transients caused by switching off other machines

Additional Benefits

Open architecture panel design
All components easily accessible
Fault register for easy troubleshooting
Hand-held data terminal for setup, changes in setup and diagnostics
Works with Series Brakes and/or Shunt Brakes - specify when ordering Duplex & Quadraplex Available
