We must pay attention to the weight of the forklift truck. It is dangerous to use it carelessly.
For balance weight forklift truck, whether it is electric balance weight forklift or internal combustion balance weight forklift truck, counterweight is an indispensable important component. The weight of the so-called balance heavy forklift truck is the fulcrum of the previous wheel location. In order to ensure the load of the fork lift fork, the fork lift truck can maintain enough adhesion on the rear wheel and the ground to ensure the fork truck to turn properly. The balance block configured in the rear of the forklift is called the counterweight of the forklift. The reference index of the traction, stability and dynamic characteristics of a balanced heavy fork truck will be restricted by the weight of the balance heavy block installed at the tail. In order to meet the lifting capacity of the balanced forklift, the required counterweight is required.
In the workshop, you can see the weight of the fork truck on the ground.
The counterweight is the balance heavy fork truck when carrying the goods, the rear wheel ensures not to leave the ground or the forward tilting, and then needs to install the balance module in the tail end of the vehicle. At this time, the traction characteristics, stability performance and dynamic characteristics of the forklift will be restricted by this module.
A balanced forklift truck with a certain amount of lifting weight is required to have a corresponding counterweight for the purpose of approaching the rated lifting amount. The load rate of the rear axle bridge of the forklift truck with high load is too high, but the smaller front axle load ratio seems unscientific and has some advantages. The full load operation of the forklift truck has the stable operation characteristics under the condition that the rear axle has sufficient bridge load; the defect is that the rear axle load rate is higher in the empty load, enlarging the rear axle load. When the diameter of the tire is increased, the flexibility of the operation becomes correspondingly poor, and the weight of the whole vehicle is too high, so that the cost-effectiveness ratio of the forklift truck will not be cost-effective.
In the case of full loading, the forklift will show smaller weight and the larger load rate of the front axle, and the less load rate of the rear axle is incongruous, but the advantage is that it has a stronger front wheel attachment force, better traction characteristics, a flexible steering, and the tire pressure and the corresponding diameter are not too large when the tire is turning. The defect is: when the load is full, the stability is poor, and there will be some accidents when the direction is adjusted. Reducing the volume of the car's operation also reduces the cost of the whole vehicle, so that the price of forklift on the market will also drop. Therefore, Wei Ma heavy industry has always attached great importance to the scientific research of the balance weight of forklifts.

In different types of products, in order to play the power of the forklift truck in the corresponding operating environment, such accessories have an important effect on the balance and the lifting of the weight. In addition to the use of this kind of iron fittings on the more large equipment of mechanical fittings, the "figure" of the weight iron can be found in other industries, such as forklift, excavating tools, elevators, bearing equipment and other fields. The application of counterweight iron not only ensures the balance of the object, but also improves the weight and touch of itself. Because the cast iron is the basic material of the weight, it is difficult to control the density of the cast material, which leads to the difference between the design and the actual weight. Therefore, the enterprise should pay attention to the tonnage of the forklift truck while choosing the forklift.
Forklift truck counterweight is also quite common, usually casting as a whole.
There are two types of weight iron that have special functions according to different forms: first, the sand and stone of natural minerals are used as the basic material, for example, shell type, ceramic type, mud type and other weight types; second, casting material selection metal, for example, solid, integral weight iron. This is the most common weight scheme at present. In general, the forklift truck of the new factory chooses the whole cast iron weight. The weight of the forklift truck is almost no worn parts compared with all the other forklift parts. We compare only a few parts with relatively high value in the forklift, the engine, the battery, the motor, the electric control, the front and back bridge, and so on, all of which will experience the process of wear, maintenance and scrap, but the weight does not exist. From the production of forklift trucks to the end of the use of forklift trucks, forklift counterweight this part in the material and function are not much different. So once the forklift is scrapped, even though the counterweight is intact, it will naturally be treated as scrap iron.

But as mentioned before, the weight of forklifts is basically integral. Enterprises in the choice of forklift are inclined to "buy big and not buy small", even in the process of use of a lot of tonnage redundancy, will not produce "car to use time hate small" feeling. But the choice of large tonnage models will meet all kinds of problems. The existence of these problems is also really seen in the eyes of many forklift operators, such as the excess of weight iron, resulting in energy efficiency loss, soft ground easy to fall into the ground and so on.
The idea of counterweight is probably similar to building blocks.
It is because of the existence of these problems that some people have proposed that the overall weight of the weight should be replaced by the modular weight module, which can change the weight of the forklift truck as a building block to choose the appropriate work weight scheme. This kind of idea is to make people feel bright. The biggest advantage of this kind of counterweight scheme is that it can be used without restriction, not only environmental protection, but also saving money. It has good economic value and ring insurance value for the manufacturers of forklift trucks, the users of forklift trucks, and the society. But at present, this is not a mature scheme, the weight change is not a simple change in weight, it has strict requirements for the overall safety performance of the forklift, so the weight scheme is still in the industry.
