Travelling by road. The sidelifter loads and unloads containers via a pair of hydraulic powered cranes mounted at each end of the vehicle chassis.The cranes are designed to lift containers from the ground, from other vehicles including rolling stock, from railway wagons and directly from stacks on docks or aboard container ships.
A logging truck or timber lorry is a large truck used to carry logs. [1] Some have integrated flatbeds, some are discrete tractor units, and some are configured to spread a load between the tractor unit and a dollied trailer pulled behind it. Often more than one trailer is attached.
The Lombard Steam Log Hauler, patented 21 May 1901, was the first successful commercial application of a continuous track for vehicle propulsion. [ 1 ] [ 2 ] [ 3 ] The concept was later used for military tanks during World War I and for agricultural tractors and construction equipment following the war.
The push-pull attachment allows two individual scrapers to act as a self-loading system, typically loading both machines in less than a minute, one after the other. Auger: uses vertically mounted auger in the bowl to pull material upwards. Pull type scraper: uses agricultural tractor, articulated dump truck, or bulldozer to pull.
A skidder is any type of heavy vehicle used in a logging operation for pulling cut trees out of a forest in a process called "skidding", in which the logs are transported from the cutting site to a landing. There they are loaded onto trucks (or in times past, railroad cars or flumes), and sent to the mill. One exception is that in the early ...
G547 "Treadway" trucks had a large hoist on the rear for self-unloading, while the G690 chassis were fitted with "Quickway" cranes, also used in bridging operations. [ 4 ] All 6-ton military trucks (of all manufacturers) had Hercules HXD 855 cu in (14 L) I6 gasoline engines, developing 202 hp (151 kW) at 2150 rpm and 642 lbf⋅ft (870 N⋅m) of ...
Log drivers at Klarälven in Sweden. Log driving is a means of moving logs (sawn tree trunks) from a forest to sawmills and pulp mills downstream using the current of a river. It was the main transportation method of the early logging industry in Europe and North America. [1]
The first modular self-propelled trailers were built in the 1970s. In the early 1980s, heavy haulage company Mammoet [6] refined the concept into the form seen today. [7] They set the width of the modules at 2.44 m, so the modules would fit on an ISO container flatrack. They also added 360° steering. [8]
