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 drive 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
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.
40th year in business.
Introduced the 72100XP, a 72,000 ft-lb., hydraulic crane with
planetary winch and 24ft. hydraulic extension.
Introduced the 4064XP. a 40,000 ft.-lb., hydraulic crane with
planetary winch and 22 ft. hydraulic extension.
- Broke ground on New Facilities. SEPT.- Offices were moved
into new facilities.
Introduced the 6036DX-22, a 36,000 ft.-lb., DC powered crane with
Power extension to 22 ft.

50 Years of customer service and dedication.
Introduced the 60100XP a 60,000 ft.-lb., hydraulic crane with
planetary winch and 24 ft. hydraulic extension.
Introduced the 3612REE and the 3612X series,12,000 ft.-lb.
electric/hydraulic crane with planetary winch powered by a 2.7 Hp permanent
