Manufacturing Cranes in the USA for 50 plus Years             

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 when loaded.

1965 Began building cranes with power rotation and power elevated booms. Rotation mechanisms were chain drive 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 its 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, Texas

1989 Hydraulically driven models developed using pressure compensated control hydraulics.

1993 Added an additional bay to the Todd facility, doubling plant capacity

1994 Proportional controls 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. This board eliminated 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.
