Description

Cargo cart for easy loading and unloading {Moving cart for easy loading and unloading}

The present invention relates to a cart for transporting cargo, and more specifically, the present invention relates to a cart for transporting cargo. More specifically, the present invention relates to a bogie for transporting cargo, and more specifically, by improving the structure of a cart for transporting cargo, it is possible to transport heavy cargo more quickly and without using a lot of manpower and force. This relates to a truck for transporting cargo that allows easy loading and unloading.

In general, cargo transport trucks are used to transport cargo in various factories, commercial buildings, or unloading locations.

Figure 1 shows a conventional bogie for transporting cargo.

Referring to FIG. 1, a conventional cargo transport bogie includes a cart (1) provided with wheels (2) to load and transport cargo, and a cart (1) so that an operator can push the cart (1) and move it to a desired location. It consists of a carrying handle (3) fixed to (1).

However, in the conventional cargo transport cart as described above, the cart (1) moves along an incline due to the weight of the cart (1) and the weight of the loaded cargo in an inclined place, so the bogie (1) must be installed only in a non-inclined place. There is a problem in that the bogie (1) must be stopped or supported by a stone or the like to prevent the wheel (2) provided at the bottom of the bogie (1) from moving.

Meanwhile, the above-mentioned cargo transport cart is also used to transport heavy drum containers containing chemicals, various industrial fuels, wastewater, etc. at work sites, and while transporting such heavy drum containers, the containers may break down. If a safety accident such as tipping over occurs, there is an inherent risk that serious casualties may occur.

Therefore, in order to prevent safety accidents from occurring at work sites where the above-mentioned heavy drum containers are transported, workers are regularly trained on safety verticals that can minimize the occurrence of safety accidents during transportation, and among these safety rules are: Although workers are required to give top priority to holding and operating cargo carts with both hands, in actual work sites, workers still operate while holding cargo carts with one hand, resulting in negligence on the part of workers during transport work using the carts. Safety accidents due to this still occur frequently.

In order to solve the above problem, the present applicant has proposed a cargo transport cart that provides a structure that allows operation only when the operator releases the brake state of each fixed wheel by manipulating each lever member while holding both hands. The technology has been applied for and registered.

Korean Patent No. 10-2204453, registered by the present applicant, includes a main body on which cargo is loaded and a pair of rotating wheels installed at the rear lower part of the main body and rotatable in the horizontal direction of the main body; A wheel portion including a pair of fixed wheels installed at the lower front of the main body, a handle portion including a pair of vertical bars extending upward from both sides of the rear upper surface of the main body, and a rear portion of each fixed wheel on one side of the main body. A pair of braking units that are installed on and normally maintain the braking state of each fixed wheel and a pair of brake units, one end of which is rotatably installed on one side of each vertical bar and the other end of which extends to the rear of each vertical bar. The lever member and each one end are coupled to the other end of each lever member, and the other end is coupled to one side of each braking part, and when each lever member is operated, the braking state of each fixed wheel is released in the direction of releasing each lever member. It is comprised of a pair of brake release units including a power transmission unit that moves the brake unit.

The above Korean Patent No. 10-2204453 states that the braking state of each fixed wheel is normally maintained by a pair of braking units, so when loading cargo, the worker places a stone, etc. on the wheel of the bogie to maintain the braking state of the bogie. No cumbersome maintenance work is required.

In addition, as previously explained in Korean Patent No. 10-2204453, operation of the bogie is possible only when the operator releases the brakes on each fixed wheel by manipulating each lever member while holding both hands. Safety accidents caused by the worker's carelessness can be prevented in advance by encouraging the worker to grip with both hands.

However, even in Korean Patent No. 10-2204453, when carrying out the task of loading or unloading heavy cargo such as drum containers onto a bogie, several workers still have to exert great effort to tilt and rotate the drum container while transporting it. Accordingly, there was a problem that not only did the loading and unloading work require a rather large amount of manpower, but it also put a lot of strain on the workers' bodies.

Accordingly, not only is productivity at the work site significantly reduced due to the loading and unloading of heavy cargo such as drum containers, which requires a lot of manpower, but also musculoskeletal disorders occur in workers who perform tasks such as loading and unloading heavy cargo for long periods of time. There were also problems that arose.

Accordingly, there is an urgent need for the development of a cargo transport truck that can easily load and unload heavy cargo onto and off the truck without requiring a large number of workers and great effort.
