Knowledge about hoists

2021-12-29
A hoist is a large mechanical device that transports materials by converting potential energy, such as mine hoists or dam gate hoists. In a broader sense, elevators, lifts, cranes, stabilizers, and even certain types of conveyors can all be referred to as hoists. Generally speaking, hoists are high-power, heavy-duty machines designed for lifting and moving substantial loads. The transportation process is carried out as power-driven machinery moves the flexible section of the steel cable—along with the cargo being conveyed—upward or downward. The steel cable is a critical component of the hoist system. Common varieties include phosphated steel cables, galvanized steel cables, stainless steel cables, and smooth-surface steel cables. Now, let’s take a closer look at one specific type of hoist: the bucket elevator.
Hoist It is a large piece of machinery that transports materials by converting potential energy, such as in mines. Hoist , Dam body Hoist And so on. Broadly speaking, elevators, Hoist 、 Hoist , stabilizer, Hoist 、 Hoist All of these can be referred to as Hoist 。 Hoist Generally refers to large-scale mechanical equipment characterized by high power and strong lifting capacity. The conveying process is carried out by power-driven machinery that moves the flexible section of the steel cable, lifting both the cargo being transported and the cable itself. The steel cable is a crucial component of the hoist. Common varieties include phosphated steel cables, galvanized steel cables, stainless steel cables, and smooth-surface steel cables, among others. Now, let’s take a closer look… Hoist The classification - Bucket-type Hoist 。
Bucket-type Hoist Used for vertically lifting lumpy and granular materials such as limestone, coal, gypsum, clinker, and dry clay, as well as powdered materials like raw materials processed through crushers, cement, and coal powder. Bucket-type Hoist Based on the discharge mechanism, bucket elevators can be categorized into centrifugal discharge, gravity discharge, and mixed discharge types. Centrifugal discharge buckets operate at high speeds, making them ideal for conveying low-abrasive materials such as powders, granules, and small chunks. Gravity discharge buckets, on the other hand, move more slowly and are better suited for handling bulky, high-density, and highly abrasive materials like limestone and clinker. Bucket-type Hoist The traction components include chain slings, plate chains, and belts.
Hoist The chain has a simple structure and is relatively easy to manufacture, and its connection to the hopper is also very secure. When conveying abrasive materials, the chain experiences minimal wear, though it does have a heavier weight compared to other options. On the other hand, the plate chain boasts a robust design while remaining lightweight, making it ideal for hoists that need to lift heavier loads—but its hinged joints tend to wear out more easily. As for the conveyor belt, it features a straightforward design, but it’s not well-suited for transporting abrasive materials. Typically, standard belt materials can withstand temperatures no higher than At 60°C, the temperature resistance of wire rope conveyor belt materials can reach up to 80°C, while heat-resistant tapes can withstand temperatures as high as 120°C. Wire rope conveyor belts themselves can handle material temperatures of up to 120°C. Meanwhile, standard chains and plate chains are capable of enduring temperatures up to 250°C.
Hoist Maintenance is an important and frequent task. It requires close collaboration with operations teams, and dedicated personnel are on duty to conduct regular inspections. Now, let’s take a brief look at… Hoist Bearing maintenance.
1. Newly installed wheels and tires tend to loosen easily and should be checked regularly.
2. Note Hoist Are all components functioning properly?
3. Pay attention to checking the wear level of easily worn parts, and be sure to replace them promptly as needed.
4. On the flat surface of the elevator car frame, dust and other debris should be thoroughly removed to prevent the moving bearings from shifting on the frame when the elevator encounters hard, non-breakable materials, which could lead to a serious accident.
5. If the bearing oil temperature rises, immediately stop the machine for inspection and identify the cause.
6. If there is a knocking sound when the rotating gear is running, stop immediately and inspect it. Hoist , troubleshoot.
