Single-speed fixed electric hoists have a very wide range of applications. Before using one, it is essential to understand its characteristics so that it can be employed more effectively. If you are interested in this topic, let’s take a look together—hopefully it will be helpful to those in the field.

Single-speed fixed electric hoists are widely used across various industries, which clearly demonstrates their broad range of applications. In fact, this single-speed fixed electric hoist is a specialized lifting device installed on bridge cranes and gantry cranes. The single-speed fixed electric hoist features a compact footprint, light weight, simple operation, and convenient use, making it suitable for industrial and mining enterprises, warehouses, docks, and other similar settings. When using such equipment, it is important to note that its structure is compact; the electric hoist with the motor shaft perpendicular to the drum shaft employs worm-gear transmission. Its drawbacks include considerable length and width, a bulky structure, low mechanical efficiency, and difficulties in manufacturing. In particular, its hydraulic system is dual-controlled, with relief valves and magnetic-contact pressure gauges that enable precise pressure regulation. The electrical control section utilizes low-voltage control, thereby enhancing the safety of the control system. Upon closer examination, we also find that its rated lifting capacity generally falls within 0.3 to 80 tons, lifting height of 3 to 30 It consists of an electric motor, a transmission mechanism, and a drum or sprocket, and is available in two types: wire-rope hoists and chain hoists. Of course, chain hoists are further divided into imported and domestically produced models, while wire-rope hoists come in single-speed and dual-speed versions. Our products are compact, versatile, and multifunctional. Naturally, our company’s offerings fully meet these requirements, and we warmly welcome long-term partnerships with customers from all over the country. After all, we enjoy a strong reputation in this industry, offering competitive pricing and reliable quality—so you can be confident that you won’t be disappointed.

 Single-speed fixed electric hoist

The single-speed fixed electric hoist employs a three-stage, fixed-axis helical gear transmission. The gears and gear shafts are made of heat-treated alloy steel. The gearbox housing and cover are crafted from high-quality cast iron, ensuring tight assembly and excellent sealing. The reducer is a separate component, making installation and removal exceptionally convenient. The manufacturer has also incorporated a device that can disconnect the main power circuit in emergency situations, as well as an upper- and lower-limit travel protection and fire-rated limit switch during production. These features guarantee the safe operation of the single-speed fixed electric hoist, extending the service life of its electrical components and ensuring reliable performance. The lifting components—including phosphating coating, galvanized wire rope, and stainless steel—comply with current national standards. GB/T5972-1986 “Practical Code for Inspection and Scrapping of Wire Ropes Used in Lifting Machinery,” ensuring long-lasting durability. The hoisting motor is a high-starting-torque, conical-rotor, brake-type asynchronous motor, eliminating the need for an external brake. The motor’s continuous duty cycle is 25% , the motor adopts B level or F Class insulation, motor protection class IP44/IP54 In fact, it is primarily a vertical electric hoist employing worm-gear transmission and oriented perpendicular to the drum’s axis. Single-speed, fixed-type electric hoists of this design are wide in width, have a bulky structure, low mechanical efficiency, and are difficult to manufacture. To date, no manufacturer produces products with this particular configuration. Currently, this product serves as our factory’s flagship offering. We are deeply grateful for the strong support from both new and existing customers. While ensuring the reliable quality of our products, we also extend favorable pricing to our broad customer base. Should you have any technical questions regarding our products, please feel free to consult us at any time.

After the introduction above, we have now gained a basic understanding of single-speed fixed electric hoists. We will continue to update other relevant knowledge in the next installment, so be sure to tune in if you have time.
