Fixed-type electric chain hoists can be classified, based on their functions and lifting methods as well as their lifting speeds, into constant-speed models and variable-frequency models. Next, let’s take a look at the installation and operating instructions for fixed-type electric chain hoists!

　　The fixed-type electric chain hoist, commonly known as a dual-speed chain hoist, can operate at high speed while also allowing for low-speed operation to ensure safety and suitability for the nature of the load and the specific job requirements. For example, when lifting simple loads where speed is not critical, the remote control can be adjusted to set the hoist to high-speed mode; conversely, when handling large or heavy loads, or when precise positioning is required, the hoist can be switched to low-speed mode, thereby ensuring safe lifting and accurate operation.

　　Fixed-type electric chain hoists can be mounted either on gantry cranes or on suspended supports, and they are also compatible with KBK overhead rails, enabling intelligent pipeline handling, reducing labor and material costs, and boosting operational efficiency. Today, we will begin by discussing the installation methods for KBK overhead rails. In practice, the installation of KBK rails shares similarities with the methods used for installing gantry cranes, I-beams, and cantilever structures. The key difference, however, lies in the unique characteristics of KBK rails compared with other systems. A pulley must be installed between each pair of guide rails, and the electric hoist is mounted on this pulley. These rails can take various forms—straight, curved, or intersecting with other rails—and the diversity of configurations is always guided by principles of convenience, practicality, and safety.

　　Today, stationary electric chain hoists are employed in a wide range of applications across both daily life and industrial production. Whether it’s residential construction, factory assembly lines, warehouse lifting operations, unloading vehicles, logistics and transportation, port scheduling, wind power generation, cargo ship operations, or bridge construction—wherever lifting equipment is required, you’re likely to find electric chain hoists at work.

　　Fixed-type electric chain hoist speeds: 2-speed, 1-speed, variable-frequency start, and 2-speed variable-frequency start. Current domestic technology is already capable of meeting the manufacturing requirements for 2-speed electric hoists.

　　Brakes for stationary chain-type electric hoists: side brakes, conical single brakes, and dual brakes (side-brake mechanical brakes).

　　Fixed-type electric chain hoists are classified into upright-lifting and inverted-lifting models, depending on the lifting method.

　　Features of the fixed-type electric chain hoist: advanced performance and design, compact size, light weight, reliable operation, and easy handling. This type of chain hoist is widely applicable for lifting heavy loads, loading and unloading operations, equipment maintenance, and cargo lifting, offering exceptional convenience in all these applications.

　　The power supply for fixed-type electric chain hoists ranges from 110 V to 690 V (currently achievable in China), with 380 V being the standard configuration.

　　The control switch voltage for fixed-type electric chain hoists is 24 V/36 V (since operating the control switch directly at the safe voltage of 36 V without a built-in transformer could pose a safety hazard to personnel, most chain hoists are equipped with a 24/36 V control voltage). The standard configuration of a chain hoist shall include limit switches and phase-sequence and phase-loss protection devices.

　　Installation Method for Fixed Chain-Drive Electric Hoists

　　First, the chain case must be installed;

　　Then, connect the power cable.

　　Before connecting the power cord, be sure to disconnect the power supply first. The grounding wire must be properly grounded, as electric shock can occur if any part of the hoist or chain comes into contact with live electrical components.

　　Third, lubricate the load chain of the electric chain hoist.

　　The degree of lubrication of a chain is one of the key factors affecting the service life of a load-carrying chain. Only timely and effective lubrication can ensure the chain’s operational lifespan.

　　Fourth, inspect the chain alignment.

　　For chain electric hoists with multiple rows of chains, do not rotate the lower hook frame. If rotation occurs, return it to its normal position and verify that the chain welds are properly aligned. Do not apply a load to a hoist with twisted chains.

　　Fifth, check the operating voltage.

　　For fixed-type electric chain hoists configured for user-specified voltages or high-voltage applications, such as 230/460 V, the wiring must be inspected to ensure compliance with the supply voltage requirements. If non-compliance is detected, refer to the instruction manual and make the necessary adjustments to meet the required operating voltage.
