Description Extended Information
Norscot NOR55112 US Army Corps of Engineers Caterpillar 623 Scraper - Tri-Color Camouflage (1:50 Scale) "Construimus, Batuimus." ("We Build, We Fight.")
- Motto of the US Navy Construction Battalion, the 'Seabees'

In civil engineering, a wheel tractor-scraper is a piece of heavy equipment used for earthmoving. The rear part has a vertically moveable hopper (also known as the bowl) with a sharp horizontal front edge. The hopper can be hydraulically lowered and raised. When the hopper is lowered, the front edge cuts into the soil or clay like a cheese slicer and fills the hopper. When the hopper is full (8 to 34 m (10 to 45 yd) heaped, depending on type) it is raised, and closed with a vertical blade (known as the apron). The scraper can transport its load to the fill area where the blade is raised, the back panel of the hopper, or the ejector, is hydraulically pushed forward and the soil or clay load tumbles out. Then the empty scraper returns to the cut site and repeats the cycle.

Scrapers can be very efficient on short hauls where the cut and fill areas are close together and have sufficient length to fill the hopper. The heavier scraper types have two engines ('tandem powered'), one driving the front wheels, one driving the rear wheels, with engines up to 400 kW (550 horsepower).

Self propelled scrapers were invented by R. G. LeTourneau in the 1930s. Two scrapers can work together in a push-pull fashion but this requires a long cut area. Special Order!

Historical Account: "Constructs" - In December 1941, with U.S. involvement in war soon expected on both oceans, Rear Admiral Ben Moreell, Chief of the Navy's Bureau of Yards and Docks, recommended establishing Naval Construction Battalions (from which the abbreviation C.B. became Seabees). With the attack on Pearl Harbor and the U.S. entrance into the war, he was given the go-ahead. The earliest Seabees were recruited from the civilian construction trades and were placed under the leadership of the Navy's Civil Engineer Corps. Because of the emphasis on experience and skill rather than physical standards, the average age of Seabees during the early days of the war was 37. More than 325,000 men served with the Seabees in World War II, fighting and building on six continents and more than 300 islands. In the Pacific, where most of the construction work was needed, the Seabees landed soon after the Marines and built major airstrips, bridges, roads, gasoline storage tanks, and quonset huts for warehouses, hospitals, and housing.

With the general demobilization following the war, the Construction Battalions were reduced to 3,300 men on active duty by 1950. Between 1949 and 1953, Naval Construction Battalions were organized into two types of units: Amphibious Construction Battalions (ACBs) and Naval Mobile Construction Battalions (NMCBs).

The Korean War saw a call-up of more than 10,000 men. The Seabees landed at Inchon with the assault troops. They fought enormous tides as well as enemy fire and provided causeways within hours of the initial landings. Their action here and at other landings emphasized the role of the Seabees and there was no Seabee demobilization when the truce was declared.
