Problems solved by technology

[0002] At present, the heavy-duty semi-trailers sold and used in the market have the defects of old structure, bulky shape and single purpose. When loading, the length and volume of the trailer cannot be adjusted according to the size and weight of the goods. It is extremely inconvenient to use and difficult to match the source of goods. It often happens that large carts pull small goods or small horse-drawn carts

Abstract

The invention discloses a multifunctional adjustable energy-saving heavy-duty semi-trailer. It changes the main beam of the trailer from a traditional fixed beam to an adjustable movable beam. The movable beam is composed of an outer beam and an inner beam. The inner beam is provided with a connecting shaft pin hole, and the length of the main beam can be adjusted by adjusting the connecting shaft pin hole. There is a carriage on the upper side of the main beam, fixed side beams are arranged on both rear sides of the carriage, a movable side beam is provided at the front end of the fixed side beam, and a movable arc beam is provided on the inner side of the movable side beam, which can be used according to the cargo. Adjust the length and height of the trailer arbitrarily. The invention has ingenious conception, unique design, economical and practical, light and energy-saving, not only reduces the production and processing cost, but also saves the operating investment of the vehicle. The development and utilization of this product will fill the gap in the same industry in China, and will be an ideal replacement product.

Description

Technical field: [0001] The invention relates to a transportation tool, specifically a heavy-duty semi-trailer whose length and load tonnage can be adjusted.
