P. & H. Brings Out New Lumber Handling 



Crane 



The combination of a new gooseneck boom arrangement with 

 gasoline operation would indicate that the new crane recently 

 put on the market by the Pawling & Harnischfeger Company, 

 Milwaukee, Wis., would serve to good advantage among hardwood 

 yards both at the mill and at the factory. 



The gooseneck extension to the boom provides for straight lifting 

 of the package of lumber without coming in contact with the boom, 

 whereas the use of gasoline power permits its operation without 

 a licensed operator, and also provides an additional safety factor 

 so far as fires are concerned. The gasoline engine, of course, con- 

 sumes fuel only when in actual operation.

Koppel Puts Out New "Electromobile" Tractor 



One of the latest appliances placed on the market for the handling 

 of lumber is the "Electromobile Tractor," manufactured by the 

 Koppel Industrial Car & Equipment Company of Chicago. This n^w 

 tractor is equipped with a lumber bolster, which the makers sa}' 

 will have a revolutionizing effect on the handling of lumber about 

 yards and mills. 



The tractor, which is electrically driven, is designed with an 

 ingenious channel frame extension in the rear, to which is attached 

 an extra heavy roller-bearing swivel bracket and large bolster 

 wheel. This wheel is built for particularly severe service and can 

 be furnished with or without rubber tire. The unit is constructed 

 for use with the ordinary two-wheel lumber buggy, and it is claimed 

 for it that a saving of six or eight men can be accomplished with 

 one of these tractors. The tractor will turn in a very short radius, 

 enabling the driver to negotiate very sharp corners between piles of 

 stacked lumber. Unloading of cars and steamers can be speeded up 

 the maximum by using one tractor and a number of buggies, the 

 lumber being carried away by the Electromobile at the rate of five 

 to seven and one-half miles an hour, making unloading one con- 

 tinuous process. In addition to the lumber bolster the tractor is 

 provided with a coupler for hauling the ordinary four-wheel fac- 

 tory trucks, which adds to the utility of the outfit. 



New Caterpillar Northern Logger Out 



A new ten-ton "caterpillar" tractor, referred to as the "North- 

 ern Logger," and especially adapted to conditions encountered in 

 logging operations in the Lake States and other regions of severe 

 winters, has just been put on the market by The Holt Manufactur- 



Koppel's Latest Lumber Handling Machine 



ing Company. This tractor represents one of the most refined pieces 

 of machinery ever introduced in the northern woods. It is not 

 merely a tractor, but is the result of a careful study of the northern 

 lumberman 's problems. Those looking at the photograph pub- 

 lished herewith will notice that the track is cut out in the center. 

 This makes it possible for snow, ice and trash to be forced out 

 through the opening by the sprockets rather than become wedged 

 between the track and the sprockets' teeth. Another very notice- 

 able improvement in this model is that the grouser or ice lug is 

 now made an integr.il part of the track shoe. It is cast solid with 



. iiiimmm.'

the shoe and is made of the same hard metal that the shoe is made 

 of, and it will wear as long as the track shoe and that is going some. 

 Every possible convenience for the operator has also been pro- 

 vided, which include the enclosed cab with sliding door, the glass 

 doors for ventilation purposes, a hod and frost fan for the radiator, 

 crankcase guard and muffler.
