High Specific Gravity Tungsten Alloy for Crane Counterweight

The reason why environmentally friendly crane counterweights use high specific gravity tungsten alloy as the key raw material is that the alloy has higher density, better corrosion resistance, and oxidation resistance. To put it more simply, the counterweight produced with tungsten alloy blocks has better practical performance, that is, while effectively extending the service life of the product, it can also improve the flexibility of the terminal product to a certain extent. In this article, let’s take a closer look at the high specific gravity tungsten alloy for crane counterweight.

The crane is widely used in a series of heavy industry products such as ships, equipment, machinery, and molds. It is mainly composed of two parts: a power unit and a bracket.

The Working Principle of the Crane

1. The power unit consists of a motor, a reducer, a clutch, a brake, a rope drum, and a steel wire rope. The motor is a magnetic single-phase capacitor motor with a mechanism for braking when the power is turned off. In addition, the motor is also equipped with a thermal switch to prevent the motor from overheating and being burned. The reducer is a two-stage gear reduction, which is fixedly connected to the motor. 

The clutch, brake, and rope barrel are integrated, but when the clutch is in a state of disengagement, it can realize rapid descent, and the operating brake can control the descent speed to avoid impact. The round hole on the front of the power unit housing can be used to install a blower, and it can be equipped with a blower for forced cooling as needed.

2. The bracket part is composed of the main rod and a rotating arm composed of a screw, a jack nut, and a vertical rod. The rotating arm can rotate 360 degrees on the main rod, and a travel switch is provided at the arm end to prevent over-lifting accidents caused by misoperation or button failure. The operation button starter realizes the motor’s forward and reverse rotation, the wire rope can be wound and released, and the support part is lifted by the pulley, and the object is lowered to complete the hoisting operation. 

Here, it is worth mentioning that, as one of the important parts of the crane, it is best to use high-density tungsten alloy as the key production material for the counterweight. Although its production cost is higher than that of lead block and iron block, it is more practical. This is mainly reflected in the fact that the alloy can achieve the goal of small size and large weight, it can be used for longer than lead and iron blocks, and it does not cause serious pollution to the natural environment.
