The invention relates to a trailer, in particular a fence transporting wood, with an on its front part The loading frame that can be placed on the floor and is suitable for sliding over the sod and two in the rear area of the loading frame coaxially arranged, freely rotating impellers

¹ In forestry, large quantities of plywood and long timber have to be transported out of forest areas with soft, poor soil every year. In such areas it is often not possible to transport wood by means of towing vehicles, because these vehicles sink into the ground and are then not maneuverable. "From these areas, wood is still mostly dragged out with the help of draft animals. This type of haulage transport is lengthy and laborious.

The sledge can either be operated by a human or in winter be dragged across the snowy ground by a draft animal. As soon as the sledge comes on hard, stable ground, it can be lifted up at its front end and pulled in the lifted state. He then just rolls on his wheels on the Floor off. This well-known sleigh has a number of essentials Disadvantages · Having the wheels of the sled with a large part of their upper half over the loading area of the sled natch, protruding from the top »must when loading the loading platform with wood Greatest care must be taken so as not to run the risk of the HoIs blocking the movement of the wheels · When pulling dee When sled across the ground, the sled stays on relatively low elevations, low tree stumps and stones hang, because the axle on which the wheels are mounted, runs at a very short distance from the ground and spreads out

extends across the entire width of the carriage. she with The amount of wood that can be transported on the sledge is very small Moving the sledge, which is usually done by a person standing between the sled horns and holding and lifting them, is very tedious and time-consuming · Langholz can with the known sleds cannot be transported at all »

suitable way. One end of the long timbers is pulled into the space between the two rear parts of the loading frame, each carrying a wheel, and placed on the middle part of the loading frame. The long timbers can for example be attached to the loading frame by means of chains or ropes. A commercially available tractor can advantageously be used to move the trailer, to which the loaded trailer is attached by means of its coupling device. For example, the trailer of a tractor can be attached to the commercially available _f hydraulic three-point lifting device. When pulling over soft ground, the trailer according to the invention can be placed on the ground with the front part of its Ladegeotells so that it slides over the ground, for example on runners or sliding surfaces, the load being evenly distributed on the ground duroh the sliding surfaces and a severe sinking is prevented. On stable ground, the trailer can be lifted so far in the front that it rests only with the wheels on the ground j The arrangement of the wheels separately from each other and below the Ledegeetells gives good ground clearance. In addition, there is a free space between the wheels that cannot be blocked by a continuous axle. The trailer can therefore also be pulled over terrain with bumps in the ground, for example tree stumps, without difficulty. In very rough terrain, the empty trailer can be brought to the loading point by hand, by means of draft animals or even by means of a tractor

and be loaded there. The towing out of the trailer from the rough terrain can then be advantageous in the Wise done that the tractor is parked at a greater distance from the trailer on solid, drivable ground and a Pull rope «wipe one attached to the tractor * from the engine driven winch and the trailer according to the invention is tensioned. The loaded trailer is then lifted by means of the winch pulled over the rough terrain to the tractor and The underside of the charging frame glides over the floor. As soon as the trailer has arrived at the tractor on firm ground, it is immediately attached to the tractor its front part raised, for example by means of the hydraulic three-point lifting device of the tractor, and then towed · The trailer according to the invention enables a Labor and time-saving removal of the wood with the help of machines even in very rough terrain · The trailer is simple and robust and is therefore very economical to buy and operate.

The trailer according to the invention is advantageously designed in such a way » that the front and middle area of the loading frame is designed as a shield bulging to the front and top » Such a sign rests on the ground with a large area when the trailer is set down on the ground. This will the weight of the load on the trailer is very even distributed on the floor. Even in soft terrain it sinks

the trailer according to the invention then only very little into the ground a. The part of the shield that is raised / oiled to the front also serves as a retaining plate, which prevents the load from slipping forward and in, for example when towing the trailer downhill Damages or injures the towing vehicle or animal towing the trailer. Especially with langholζtransport, the Front ends resting on the trailer when towing downhill do not slide forward, but hit the arched part of the shield.

A favorable design of this trailer according to the invention is also given that at least two pulleys are freely rotatably mounted on the front part of the loading frame one in the area of the front upper edge of the loading frame. " and one is arranged in the lower region of the front raised part of the loading frame, and that a rope is guided over the pulleys is one of the free end of the upper roll for towing and attaching cargo can be guided to the rear over the loading frame and the other end of the lower roller is led forward to the suspension device of the towing vehicle, for example to a V / inde. In this embodiment of the With the trailer, the cargo can be towed to the trailer by means of the rope. The wheels of the trailer be fixed by means of brake pads. The trailer can also be loaded by means of the rope by a rope attached to one end in the rear area of the loading frame is looped around the cargo, the other end of the rope End with the free end coming from the upper roll up to the
