RTA 167-69283Nm Square Drive Hydraulic Torque Wrench

RTA Square Drive Hydraulic Torque Wrench

The Baier RTA Series is designed for controlled tightening and loosening of industrial bolted connections. Ten models cover 167–69,283 N·m across the series, with model-specific square drives from 3/4 to 2 1/2 inches and catalog-listed bolt ranges from M16 to M150.

Key Features

• ±3% torque accuracy: Supports repeatable controlled bolting when the correct model, pressure setting and operating procedure are used.

• 700 bar / 10,000 psi operation: Works with a compatible high-pressure hydraulic pump and hose system.

• Integrated Al-Ti alloy body: Combines high strength with lightweight construction for industrial handling.

• 360° fine-adjustable reaction arm: Supports positioning against a suitable solid reaction point.

• 360° × 180° rotatable oil-pipe fitting: Allows more flexible hose orientation around nearby equipment.

• Interchangeable square drive: Model-dependent drive sizes support different socket and bolting requirements.

• Anti-corrosion surface treatment: Supports work in demanding industrial environments.

• On-tool setting reference: A laser-engraved pressure-to-torque comparison table is provided on the cover plate.

System requirement: The wrench cannot operate independently. A compatible hydraulic pump and hose system is required.

Industrial Bolting Applications

The RTA Series supports controlled tightening and loosening within the selected model's rated torque, bolt, drive and dimensional limits.

Wind Power

Select the model by required torque, fastener size, available clearance and reaction point for wind-power installation and maintenance tasks.

Oil and Gas Flange Work

The RTA range supports controlled flange-bolt tightening and loosening where the selected tool can be positioned with a safe reaction point.

Mining Equipment Maintenance

RTA models can be selected for controlled tightening and loosening of heavy bolted connections on mining equipment.

Other Heavy Industrial Bolting

Suitability depends on required torque, bolt and socket size, joint condition, working clearance, reaction geometry and hydraulic-system compatibility.

Model Selection and Supply Scope

Choose the model by required working torque first. Then verify bolt size, drive and socket requirements, wrench dimensions, available clearance and a solid reaction point.

1. Required tightening or loosening torque

2. Bolt or nut size and fastener geometry

3. Joint drawing or clear photos with dimensions

4. Available radial and height clearance

5. Safe reaction-point position

6. Required drive and socket type

7. Quantity and destination market

8. Required project documentation

Loosening selection: The catalog recommends a wrench with torque capacity of at least 150% of the bolt-tightening torque for loosening and bolt removal.

Required but Not Included
