ATHLO chain EX
(Zone 2)
ATHLO chain EX has been designed for use in explosive environments and complies with the latest safety regulations and is certified both ATEX and IECEx for Zone 2. With a lifting capacity of up to 2,500 kg and an extensive range of configurations, the chain hoist can be perfectly tailored to specific requirements.
Even in the standard version, the load can be moved steplessly and smoothly thanks to the frequency inverter. The wide operating temperature range enables the safe use of ATHLO chain EX in various industries for numerous applications.
Additional models for further load ranges, equipment options, and EX zones will follow.

Flexible integration
优势：
- Variety of suspension options
- Compact design and optimal C-dimensions
ATHLO chain EX can be integrated into different work and production processes with ease. There is a variety of mounting options available, all of which ensure safe operation and easy handling.
Thanks to its compact design, it can fully exploit its advantages even in limited space.
-
Powerful and safe
优势：
-
High-performance hoist motor with overheat protection,
2-step hoist speed up to 16/2.7 m/min - Gear limit switch (slow and stop)
- Overload protection via slipping clutch
- Low-maintenance hoist brake in the gear train (electromagnetic disc brake)
ATHLO chain EX masters demanding requirements with ease. The motor is protected against overheating, thus always providing safe operation.
The limit switch for the gearbox allows for easy adjustment of the work area and reliably limits the lifting range, first by slowing down and then by stopping.

High-performance hoist motor with overheat protection,
-
Reliable control
优势：
- Increased reliability and safety due to fixed wiring
- Secure sealing of cable entries and penetrations meet the strict requirements for explosion protection; cable penetrations for pressure-resistant encapsulation are potted (from EX d to EX e area)
The electrical control of ATHLO chain EX is hardwired. This increases the reliability and safety of the hoist by reducing the number of transfer points.
-
Robust housing
优势：
- Encapsulated and durable housing (IP66)
All components are explosion-proof and tested to ensure the maximum safety of the chain hoist and thus the entire work process.
-
Certified safety
优势：
- ATEX (Zone 2)
- IECEx (Zone 2)
ATHLO chain EX has been developed and certified based on the latest safety regulations.
-
Potential equalization
优势：
- Reliable protection against spark formation through potential equalization of the components
The potential equalization of ATHLO chain EX prevents the generation of static electricity and minimizes the risk of spark formation.
-
Gentle handling
优势：
- Stepless speeds of the motorized trolley (frequency inverter)
- Overheating protection of the trolley motor
The motorized trolley enables precise and effortless positioning of heavy loads, increases efficiency, and reduces physical strain on the user. The loads can be moved steplessly as standard (frequency inverter).
-
Control panel
优势：
- 2-step push-button
- Robust housing (IP65)
The control panel can be customized to individual needs and expanded to include additional functions (e.g., horn).
Electric Chain Hoist
Types
Die Hubwerkseinstufung (FEM/ISO) ist eine Kennzahl die sich primär aus der mittleren täglichen Laufzeit des Krans und der tatsächlichen Last zusammensetzt. Hierbei wird auch berücksichtigt wie oft das Hebezeuge hierbei Höchstbeanspruchungen oder nur geringen Beanspruchungen ausgesetzt ist oder wie viele Starts/Stops erfolgen.
Vereinfacht:
1Am / M4 = Die mittlere tägliche Laufzeit beträgt rund 1 Stunde und das Hebezeug wird häufig höchstbeansprucht und laufend mittleren Beanspruchungen ausgesetzt.
2m / M5 = Die mittlere tägliche Laufzeit beträgt rund 2 Stunden und das Hebezeug wird häufig höchstbeansprucht und laufend mittleren Beanspruchungen ausgesetzt.

Applications
Potentially explosive areas for gases and dusts
“EX zones” are defined based on the type, duration, and frequency of the occurrence of
explosive atmospheres. These determine the protective measures to be taken.
EX zone 2, for example, is a potentially explosive area in which a hazardous, explosive
atmosphere does not normally occur or only occurs for a short time during normal
operation. The substances are gases, vapours or mists that can form an explosive mixture
when combined with air.
| Zone | Probability of an explosive atmosphere | |
| Gases | Dusts | |
| 0 | 20 | Very high - explosive atmosphere present continuously or very frequently |
| 1 | 21 | High - explosive atmosphere occasionally present |
| 2 | 22 | Low - explosive atmosphere rarely present |
