Maintenance and handling of the electric chain hoist explained:
Maintenance and care of the load chain / chain lubrication
Every electric chain hoist has a load chain that is subject to enormous stresses. To minimize wear on the load chain and the chain sprocket of the hoist and to prevent damage to the load chain and the chain hoist, it is necessary to check and lubricate the load chain regularly.
Maintenance and care of the load chain / chain lubrication
With a double fall electric chain hoist, there is a risk of the load hook twisting. In addition to the descriptions in the operating instructions, the video presents the problem of twisted load hooks and provides instructions for the correct positioning of the load chain including the load hook.
Electric chain hoist applications
Electric chain hoists are primarily used on crane systems or rail systems in conveyor technology. They can also be installed in stationary applications. Special applications include the stage and entertainment industry. Various standards can apply here, depending on the requirements profile. These classifications within the BGV standards specify in detail which technical requirements electric chain hoists must fulfill for the respective application.
Employer's liability insurance association regulations specify in detail which technical requirements electric chain hoists must meet for the respective application.
Electric chain hoists - Categorization

- Only suitable for lifting and lowering loads. It is not permitted for a person to stand under the load lifted by the electric chain hoist
- Electric chain hoist according to DGUV regulation 54 Plus:
- Suitable for lifting and lowering PLUS for holding loads. It is permissible for persons to stand under the load being lifted by the chain hoist, provided that the load is not being moved at the time.
- Electric chain hoist in accordance with DGUV regulation 17:
- Meets the highest safety requirements: Use of electric chain hoists with, among other things, 2 redundant brakes that allow people to stand under the electric chain hoist while the loads are being moved.
- What are electric chain hoists?
- An electric chain hoist is a tool used to lift heavy loads with the aid of an electric motor, an output shaft with chain wheel and the load-bearing equipment (load chain and load hook).
- Design and mode of operation
- The motors can be switched via direct control or contactor control.
- Electric chain hoists can be designed for an operating voltage of 3-Ph/400 Volt/50 Hz or 1-Ph/230 Volt/50 Hz. Ask our experts about special voltages, which we will be happy to configure for you on request. Both a frequency-controlled and a pole-changing motor can be used as a hoist motor. A chain hoist with a pole-changing motor can be configured with one or two speeds (fine stroke or main stroke).
- The gearbox reduces the speed of the hoist motor.
- The chain sprocket ensures power transmission from the drive shaft to the load chain.
- There must be a positive connection between the chain sprocket and the round steel chain.
- The load chain is available in two versions: as a round steel chain or as a profiled steel chain.
- The hook block is the part of the chain hoist to which the load or load handling attachment is attached.
- A chain box, made of sheet metal, plastic or fabric, is used to hold the load chain.

Selection guide for electronic chain hoists
What should you look out for when buying electric chain hoists? This guide can help you to get an initial idea of which chain hoist could be suitable for your application.
1. selecting the load capacity
What load do you want to lift?
It is better to choose the next higher load capacity level, as the automatic overload protection will stop your chain hoist if it is overloaded.
2. classification of the operating mode
How many times per day/hour do you expect to use the appliance?
The ISO (FEM) classification provides information on the maximum number of operations on the control switch per hour. The operating group classification can usually be found in the detailed view. The higher the number after the “M”, the more intensively the electric chain hoist can be used.
| Operations per hour | Duty cycle |
M3 (1Bm) | 150 | 25% ED |
M4 (1Am) | 180 | 30% ED |
M5 (2m) | 240 | 40% ED |
M6 (3m) | 300 | 50% ED |
M7 (4m) | 360 | 60% ED |
3. lifting height
Two factors play a role in determining the correct lifting height for your electric chain hoist:
- The pure lifting height: This is the distance over which you want to move your load.
- The suspension height: This is the height at which the chain hoist is suspended.
The suspension height is also decisive for the length of the control cable of the control block if you opt for a wired floor control system.
4. type of control
We distinguish between two basic types of control:
- Direct control
- With directly controlled chain hoists, the operating voltage of 400 V is applied directly to the control unit. Due to the simpler design, these chain hoists are somewhat cheaper, but the risk of injury in the event of a possible defect is increased. The variants with direct control can be found here: T-ECHO and ST.ECO.
Contactor control - Depending on the version, electric chain hoists with contactor control have 24 V or 42 V control signals on the control unit.
- The frequency inverter control. The lifting and lowering speeds can be infinitely varied. In addition, loads can be started up and set down smoothly.
5 The lifting speed
You can choose between three different types of speed control:
- one lifting speed
- two lifting speeds (main hoist and fine hoist) by means of pole-changing.
Electric chain hoists with main and fine lifting speeds are particularly recommended for positioning heavy loads.
Infinitely variable speed
Our standard hoist speeds are 8 m/min, main stroke, with 2 m/min fine stroke. The P model can achieve a main hoist speed of over 20 m/min for loads up to 500 kg. As a rule, the greater the load to be lifted, the slower the lifting speed. The number of chain strands also has an influence on the possible speed. Chain hoists with only one chain strand generally have a more powerful motor than double-strand electric chain hoists with the same load capacity and can therefore lift or lower the load faster.

FAQ: Questions and answers about electric chain hoists
- Is a chain hoist a crane?
A chain hoist is not a crane as such, but a lifting device that can be used in conjunction with a crane or other lifting device. The chain hoist is therefore a component of the crane, but is not a crane in its own right.
For the purposes of this accident prevention regulation DGUV V52, cranes are hoists that can lift loads with a load-bearing device and also move them in one or more directions,
- What types of electric chain hoist controls are there?
Electric chain hoists can be operated using different types of control. One option is direct control, in which a control current of 400 V or 380 V is used. Another type is contactor control, which works with a lower control current of 24 V or 42 V. Both types of control are widely used in industry and are selected depending on the application and safety requirements.
- Which suspensions and trolleys are possible with electric chain hoists?
There are various suspension and movement options for electric chain hoists. Eye suspension and hook suspension are used for stationary attachment. Rolling trolleys, reel trolleys and electric trolleys are available for mobility. Roller trolleys allow manual movement, reel trolleys allow movement by pulling on a chain, and electric trolleys offer motorized movement for maximum efficiency and comfort when moving loads.
- Ambient conditions:
Depending on their degree of protection, electric chain hoists can be used indoors or outdoors. For outdoor use, a chain hoist with protection class IP65 should be used. In any case, it is advisable to provide weather protection against precipitation. Chain hoists are designed exclusively for vertical operation.
- Electric chain hoists for explosion-proof areas
Chain hoists specially manufactured for the ATEX area are produced in accordance with the classification of potentially explosive atmospheres:
Flammable substances Classification of potentially explosive atmospheres Device group Device group Probability Gases & vapors Zone 0 Ii 1G Constant, long-term, frequent Gases & vapors Zone 1 Ii 2G or 1 G Occasionally Gases & vapors Zone 2 Ii 3G or 2G or 1G Probably not Dusts Zone 20 Ii 1D Constantly Dusts Zone 21 Ii 2D or 1D Occasionally Dusts Zone 22 Ii 3D or 2D Probably not
