Founded by a group headed by Dan Moore to manufacture electric cranes for 12V DC applications. The first units were manual rotation and the boom angle could not be changed while loaded.
Began building cranes with power rotation and power elevated booms. Rotation mechanisms were chain driven and booms were raised by a cable system.
First Cylinder raised boom model designed.
Business purchased by Herb Koenig, Jr.
First crane built using worm gear rotation mechanism.
Planetary winch used on hoisting function for the first time. Because of it's efficiency these units have become the standard in the crane industry.
First slewing ring with internal gear drive used on rotation drive.
Moved shop and offices to 11505 Todd St. Houston, TX.
Hydraulically driven models developed using pressure compensated control hydraulics.
Added an additional bay to the Todd facility, doubling plant capacity.
Proportional control system added to hydraulic cranes.
Cranes with either a load sensor or an anti two-block were equipped with a microprocessor to monitor these functions and drive the monitored functions, eliminating the mechanical relays previously necessary.
Moved the machine and welding shop to an outside facility adding over 15,000 square feet to the company's productive capacity.
