ATEX crane system with electric chain hoists

ATEX CRANE SYSTEM WITH ELECTRIC CHAIN HOISTS

A crane system designed for safe and precise load handling in explosion-hazardous areas. The integrated setup includes two overhead travelling cranes and two electric chain hoists, which work together to efficiently move loads of up to 2.5 tonnes. Thanks to the use of explosion-proof (ATEX) components, the equipment ensures the highest level of safety in EX zones (Zone 1).

FEATURES OF THE ATEX CRANE SYSTEM

Thanks to the implemented control solutions, the operator has full control over the crane and hoist movement in three directions: crane travel, trolley travel, and lifting/lowering the load. The devices operate smoothly and precisely, significantly improving transport efficiency in production environments, especially in explosion-risk areas.

• each crane and hoist is equipped with pendant control stations, allowing precise operation of all functions,

• the drive systems of cranes and hoists enable smooth starts, speed control, and accurate stopping at the desired position,

• installed limit switches ensure safe movement boundaries and prevent collisions,

• the hoist moves along a curved track, which meets logistical needs and reduces the number of transport devices to a necessary minimum,

• power supplied via conductor rails ensures continuous and failure-free operation along the entire length of the tracks.

OPERATING MODES – FUNCTIONALITY AND SAFETY

The system can operate in three modes:

• manual mode – the operator controls the devices manually using a pendant station, with full control over each movement,

• semi-automatic mode – the operator initiates movement, but the system automatically stops the device after reaching the set positions,

• automatic mode – the devices perform pre-programmed sequences of tasks, minimizing operator involvement.

The system is equipped with limit switches that prevent exceeding the permissible range of motion and immediately stop the device in case of obstacle detection.

BENEFITS OF THE SYSTEM

• safe operation in explosion-hazardous areas (ATEX Zone 1),

• high precision and smooth movements thanks to inverters and optimized drives,

• possibility of cooperation between crane and hoist within one operating cycle,

• three working modes adapted to various production tasks,

• easy control and intuitive operation via pendant stations,

• optimized track layout – including curved hoist travel – ensures transport system flexibility.
