Battery Torque Multiplier EAF 2/150, torque range 150 - 1.400 Nm, square driver 3/4 inch

The battery torque multiplier EAF 2/150 model 43033 is a portable torque tool designed for tightening and loosening bolts across a torque range of 150 to 1,400 Nm (160-1035 ft.lbs.). The unit employs a 3/4 inch square drive output. It integrates a brushless synchronous motor that reduces wear and eliminates routine maintenance requirements.

The portable design combines with lithium-ion 5.2 Ah battery power to provide flexibility on job sites without fixed electrical supply. The automatic pressure relief system activates after reaching target torque to protect bolt threads and extend tool life.

The complete package includes a standard support arm, two battery packs, a 230V charger, calibration certificate, operating and service manual, and a dedicated carrying case. The brushless motor architecture delivers consistent performance while minimizing component degradation over extended use cycles.

Technical construction of the battery torque multiplier EAF 2/150

Torque output and drive configuration

The tool provides a working torque span from 150 Nm to 1,400 Nm, equivalent to 160-1035 ft.lbs., addressing a wide range of fastener sizes and material specifications. The 3/4 inch square drive output accepts standard sockets and adapters. The brushless synchronous motor eliminates carbon brush replacement and reduces internal friction. The automatic relief function disengages drive force once the preset torque threshold is reached, preventing over-torquing and fastener damage.

• Torque range: 150-1,400 Nm (160-1035 ft.lbs.)
• Square drive size: 3/4 inch
• Motor type: brushless synchronous
• Automatic pressure relief function
• Battery type: lithium-ion 5.2 Ah
• Number of batteries included: two
• Charger voltage: 230V

The brushless motor design contributes to lower heat generation and extended operational intervals between service checks. The lithium-ion battery chemistry supports rapid charging cycles and maintains capacity over repeated discharge events. The standard support arm stabilizes the tool during operation, reducing operator fatigue and improving torque accuracy.

Power supply and battery system

The EAF 2/150 operates on two lithium-ion batteries rated at 5.2 Ah each. The dual-battery configuration allows continuous operation by swapping depleted packs with charged units. The included 230V charger restores battery capacity for subsequent work cycles. The battery management system monitors cell voltage and temperature to prevent overcharge and thermal runaway conditions.

• Battery chemistry: lithium-ion
• Battery capacity: 5.2 Ah per pack
• Quantity of batteries: two
• Charger input voltage: 230V
• Maintenance-free motor operation

The brushless motor eliminates the need for periodic brush inspection and replacement, reducing downtime and consumable costs. The automatic relief mechanism protects both the tool and the fastener by halting torque application at the configured limit. The calibration certificate documents traceability to recognized torque standards, supporting quality assurance protocols in regulated industries.

Common applications for the battery torque multiplier EAF 2/150

This battery-powered torque multiplier serves industrial maintenance, assembly line operations, and field service tasks where precise torque control is required. Typical applications include wind turbine assembly, heavy machinery maintenance, pipeline flange connections, and structural steel erection. The portable design suits remote locations and elevated work platforms where pneumatic or hydraulic power sources are impractical. The torque range accommodates fasteners from medium to large diameter, covering M16 to M36 metric bolts and equivalent imperial sizes under standard tightening specifications.

Scope of delivery and documentation

The complete delivery package for model 43033 includes the battery torque multiplier unit, standard support arm, two lithium-ion batteries rated at 5.2 Ah, one 230V battery charger, calibration certificate, operating and service manual, and a protective carrying case. The calibration certificate provides documented torque accuracy at the time of shipment.

The operating manual details setup procedures, torque setting adjustments, battery charging protocols, and routine inspection intervals. The carrying case protects the tool and accessories during transport and storage.
