This beautiful reproduced borderless b&w 8x10 photo is from my personal collection. “SAMPLE†will not appear on the photo you purchase ... it is only on the scanned image. NOTE: While not being a true ‘historian’ or a construction industry ‘expert’, I have picked up a pretty good working knowledge over my 50+ years working around the heavy construction industry. The details that follow are true to the best of my knowledge, however I welcome any and all corrections and/or additions to this information ... please contact me with your suggestions or information. Thanks! The more I studied this amazing photo, the more details I saw and the more fascinated I became. It can best be described in 3 parts: first the P&H MODEL 600 SHOVEL. Made in Milwaukee by the Harnischfeger Corporation under the trade name P&H, this Model 600 Shovel appears to be about a 1 yard machine, correct me if you know better. P&H called their early crawler tracks “corduroy’ cranes, and this name can be seen on the top of the rear 2-piece counterweight above the “Model 600†raised lettering. This photo is very clear and shows so much detail ... from the large rock wedged under each track to keep it from rolling, the tow chain seen under the turntable, the rolled up full-length sidecurtain, both the operator and his oiler visible on the machine, engine detail and roof mounted right-angle exhaust stack, rivet detail on the boom and bucket, “P&H Model 600†visible on the shovel boom, the dipper trip cable, right up to the rock wedged between two of the bucket teeth. The shovel cab appears to be all steel, no wooden construction. The entire right side of the shovel opens up for ventilation, unlike a shovel built for northern weather with side panels and windows. Henry Harnischfeger came to the U.S. from Germany in 1872, eventually moving to Milwaukee. With partner Alonzo Pawling, they founded Pawling & Harnischfeger Co. in 1884. By 1911 Harnischfeger bought out Pawling’s interest, but in respect to Pawling, the company always kept his name in the “P&H†tradename. A prominent manufacturer of cranes, shovels, and draglines of many sizes for all types of construction up into the late 1900’s, P&H now builds mostly very large equipment for the global mining industry. In the 1960’s P&H licensed Kobe Steel to produce P&H cranes and shovels in Japan. That lead to Kobe developing hydraulic excavators for today’s world market under the KOBELCO name. The MACK “AC†DUMP TRUCK. The famous Mack Model “AC†was the truck that made Mack famous around the world, and was known as the “Bulldog†Mack for its rugged dependability in WWI Europe ... a nickname that stuck and gave rise to the phrase “Tough as a Mack truckâ€. Some 40,200 “AC†Macks were produced from 1916 to 1938, one of the longest production runs of any model truck. Built with a 4-cylinder gas engine with side-mounted split-radiators, and a 4-speed transmission with chain-drive, the “AC†was a fairly slow truck, but built very sturdy and was a most popular heavy-duty dump truck for its entire production life and many years to follow. Many of these AC Bulldog Macks ran well into the 1950s ... amazingly sturdy trucks! This AC Mack, which appears to be fairly new, as the hard rubber tires look almost unused, the fenders have no dents, and the hood and front sheet metal work looks unscathed. This is truck #37 of the WARREN BROTHERS COMPANY fleet, with company name painted on the front hood of the AC and on the side of the dump body. This truck has a ‘motormeter’ on top of the radiator tank to advise the driver of the operating temperature of the engine ... and the driver could adjust the side louvers on the side-mounted split-radiators to open or close for more or less cooling. The open C-cab was the first truck cab to be made of steel, but had no side windows. The doors slid up and down in ‘pocket’ side-tracks, and the C-cabs were often fitted with canvas side-curtains for inclement weather ... which can be seen tightly rolled up on this truck. This AC Mack appears to have a wooden windshield ‘frame’ with top-hinged windshield panels ... and this truck has the driver’s windshield in full open position for ventilation. This truck is also equipped with both front mounted headlights and ‘Adlake’-style side-lanterns mounted on the cowl side, both of which were probably gas operated. From what I can tell, this AC Mack would have been built after 1922, since it has the louver radiator shutters, instead of the earlier mesh screen. WARREN BROS. CO. Warren Bros. of Boston was active in Cuba in the 1920s, and was one of two contractors to build the “Carretera Central†in 1928, the new Central Highway that would traverse Cuba from end to end, uniting the principle cities of the island and opening traffic in the six provinces. This photo may be from the Central Highway project, but I can not be sure. The Central Highway was built 6 meters wide between cities and 8 meters wide in towns, on a concrete base of about 6â€, covered in the country with an asphaltic paving material known as “Warren Bituliteâ€, and granite blocks in the cities. The name “Warren Bros. Bitulitic†can be seen painted on the front hood of the AC Mack. Warren Bros. Co. was founded in Boston, Mass. in 1879, and was one of the early pioneers in both asphalt and concrete road construction. Warren Bros. was purchased by Ashland Oil in 1966, and soon became known as Ashland Paving and Construction or APAC, headquartered for some time in Birmingham, AL. In 2006 the paving and construction division of APAC was sold to Oldcastle Materials, and now operates as APAC with headquarters in Atlanta and operations in 14 Southeastern and Midwestern states.
