Our History
1961
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.1965
Began building cranes with power rotation and power elevated booms. Rotation mechanisms were chain driven and booms were raised by a cable system.1969
First Cylinder raised boom model designed.1983
Business purchased by Herb Koenig, Jr.1983
First crane built using worm gear rotation mechanism.1983
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.1986
First slewing ring with internal gear drive used on rotation drive.1987
Moved shop and offices to 11505 Todd St. Houston, TX.1989
Hydraulically driven models developed using pressure compensated control hydraulics.1993
Added an additional bay to the Todd facility, doubling plant capacity.1994
Proportional control system added to hydraulic cranes.1998
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.1998
Moved the machine and welding shop to an outside facility adding over 15,000 square feet to the company's productive capacity.2001
