Introduction of Low Bed Semi Trailer for Sale Tanzania
Low bed semi trailer for sale Tanzania is suitable for the transportation of various mechanical equipment, large objects, highway construction equipment, large tanks, and power station equipment. It is widely used because of their efficient and fast functionalities. The whole vehicle adopts advanced computer-aided design software and the optimization design is flexible and diverse. The frame bearing surface can be designed according to user requirements to meet the transportation of various special goods.
The axle of the low bed semi trailer for sale Tanzania is placed behind the center of gravity of the vehicle when the vehicle is evenly loaded. A coupling device is equipped that can transmit horizontal or vertical force to the trailer. The front part of the trailer rests on the rear of the tractor truck. Normally, lowbed semi trailer can be divided into two types: two-axle and three-axle. Both come with front outriggers, also known as landing gear. This type of semi trailer is usually below 13 meters, while it can sometimes reach 17.5 meters upon customer’s request.
Prolong Service Life of Low Bed Semi Trailer for Sale Tanzania
The low bed semi trailer for sale Tanzania needs to have a water spray system before leaving the factory because in long-distance transportation, long-term beraking will cause the wheels to heat up. If cooling is not used, the effect breaking will be reduced or even completely ineffective. Meanwhile, the service life of wheels, tires, and the whole trailer will also be reduced. Enough attention must be paid to this to prolong the overall service life of the trailer. No matter the size of trailer, there should be comprehensive consideration before purchasing. A few specifications of the trailer include its appearance, color, configuration, and fuel efficiency.
Main Structure of Low Bed Semi Trailer for Sale Tanzania
The frame of low bed semi trailer for sale Tanzania is normally a welded part composed of 2 longitudinal beams, 13 cross beams, 18 wing beams, and 2 side beams. To ensure the transportation safety of the crawler-type construction machinery, the height of the bearing surface should be reduced as much as possible in the design. Therefore, the frame adopts a concave beam structure.
The longitudinal beam is the main load-bearing part of the frame. It is subjected to large bending stress during transportation. In order to meet the performance requirements of the low bed semi trailer for sale Tanzania, the longitudinal beam adopts a stepped structure. The section is I-shaped and the material is 16Mn. To ensure sufficient space for the hoisting device and the suspension system, the transaction section is designed at the gooseneck and the height of the suspension support is reduced as much as possible..
Cross Beam Structure
The cross beam is the main component in the frame used to connect the left and right longitudinal beams. The torsional performance of the beam itself and its distribution directly affect the internal stress of the longitudinal beam and its distribution. Reasonable designed beams can ensure that the frame of low bed semi trailer for sale Tanzania has sufficient torsional rigidity.
In order to simplify the manufacturing process, principle of product design standardization, serialization and generalization is followed. The beam at the gooseneck of low bed semi trailer for sale Tanzania adopts the same groove section as the ordinary semi-trailer of our factory.
The low bed semi trailer for sale Tanzania has a double or triple rear axle structure and adopts a double or triple axle balanced suspension system. The front, middle and rear suspension supports are directly welded to the lower wing surface of the longitudinal beam. When the trailer is traveling, since the suspension part of the frame bears a large torsional stress, a box-shaped beam with a large cross-sectional size is set at the front. Middle and rear supports to ensure that the frame has sufficient torsional rigidity to achieve ideal load transfer.
Middle of The Frame
Due to the high torsional stiffness at the kingpin and rear axle, the deformation in the middle of the frame tends to be large. In order to allow the frame to have a small amount of warpage for low bed semi trailer for sale Tanzania, six I-shaped beams welded with the longitudinal beam web are arranged in the middle of the frame. The distance between the beams is about 800mm.
Connection between Cross Beam and Longitudinal Beam
The joint stiffness of the connection between the cross beam and the longitudinal beam directly affects the overall stiffness of the frame. The rational design of the joint structure of the cross beam and the longitudinal beam is an important factor in the design of the frame. There are usually two forms of connection for Connection.
In order to meet the needs of crawler-type construction machinery transportation, the frame of low bed semi trailer for sale Tanzania is designed to be a special structure with a raised width according to the size of the crawler. The gooseneck and suspension support are only as wide as the outer edge of the longitudinal beam. A box-shaped bracket with a larger cross-sectional size is set at the front, middle, and rear suspension supports. The height of the bracket is equal to the diameter of the tire. The tire and the bracket bear the load until the construction machinery travels.
