The Baier BRDC-SS4000 is a controlled, non-impact cordless torque wrench for selected wind turbine assembly and maintenance tasks. It delivers 600–4000 Nm through a 1 in square drive with ±5% torque accuracy and ±2% repeatability. Its Metabo-brand brushless motor and Metabo-brand 18 V LiHD battery support elevated, remote and nacelle-area bolting without an external power cable, hydraulic pump or hose.
600–4000 Nm | Adjustable torque range for selected medium- to high-torque wind maintenance tasks |
Controlled output | ±5% accuracy | ±2% repeatability | non-impact operation |
Metabo drive platform | Metabo-brand brushless motor | Metabo-brand 18 V LiHD battery |
Project options | Tightening records | optional connectivity | custom reaction-arm support |
Cordless Access
Work in elevated and remote areas without routing an external power cable, hydraulic hose or pump to the tightening point.
Controlled Torque Output
Digital torque setting, ±5% accuracy and ±2% repeatability support controlled tightening within the model range.
Project Data Options
Supported configurations can store tightening records and add Wi-Fi, Bluetooth or 4G connectivity for project data requirements.
Reaction-Point Matching
Standard and custom reaction arms can be assessed against joint geometry, available space and the real reaction point.
Model selection note
For routine repetitive operation, the specified working torque should normally remain at or below approximately 80% of the model maximum - about 3200 Nm for BRDC-SS4000.
· Nacelle equipment mounting and service
· Gearbox and generator bed bolting
· Selected hub and bearing connections
· Selected yaw-system fasteners
· Component replacement and scheduled maintenance
· Elevated field work where external cables or hoses restrict access
Important application note Suitability depends on the wind turbine manufacturer's approved tightening procedure, specified torque, bolt and socket size, reaction point and available operating space. BRDC-SS4000 does not automatically replace hydraulic torque wrenches or hydraulic bolt tensioners for foundation bolts, large tower-flange connections or other critical joints. |

The digital interface shows operating information including torque value, battery level, operating mode and temperature. Buzzer alerts and tightening-result feedback support the operator during the tightening cycle.
Data storage, export, remote software support and connectivity modules are configuration-dependent. Confirm the required functions before ordering.
Reaction-arm geometry must match the real support point and available operating space. Baier can assess standard curved, Z-type, double-force, four-point and sliding-arm options, as well as custom geometry for confirmed projects.
Provide joint photographs or drawings, socket size, surrounding clearances and the proposed reaction point before finalizing the arm.

To confirm whether BRDC-SS4000 matches the wind turbine joint, request the following information:
· Required tightening torque and approved tightening procedure
· Bolt and socket size
· Wind turbine component or bolting position
· Available reaction point and surrounding clearance
· Application photographs or drawings
· Required data-recording or communication functions
If the normal project torque is frequently above approximately 3200 Nm, Baier will assess a higher-capacity cordless, electric or hydraulic torque solution.

Is BRDC-SS4000 suitable for every wind turbine bolt?
No. It is intended for selected joints whose specified torque, socket size, reaction point and operating space match the tool. Foundation bolts, large tower-flange connections and joints requiring hydraulic tensioning must follow the turbine manufacturer's approved procedure.
What is the torque range of BRDC-SS4000?
The adjustable torque range is 600–4000 Nm. For routine repetitive work, the target torque should normally remain at or below approximately 3200 Nm.
Which wind turbine areas can be assessed for this model?
Typical assessment areas include nacelle equipment, gearbox and generator beds, selected hub and bearing joints, selected yaw-system fasteners and elevated maintenance tasks.
Are tightening-data and wireless functions standard?
Not in every configuration. Up to 65,536 records and Wi-Fi, Bluetooth or 4G modules are available on supported configurations and must be confirmed before ordering.
Can the reaction arm be customized?
Yes. Standard and custom reaction-arm options can be assessed from the joint drawing, socket size, available clearance and real support point.
What is included in the standard package?
The typical package includes the wrench, two batteries, charger, USB data cable, standard reaction arm, Allen key, carrying case, user manual, calibration report, certificate of conformity and warranty card. The final packing list is confirmed per order.
Which documents identify BRDC-SS4000?
The supplied EMC, LVD and RoHS conformity documents identify BRDC-SS4000. A separate Verification of Conformity also lists BRDC-SS4000 among its product types. Applicability must be confirmed for the supplied configuration and destination market.
Baier provides a 12-month warranty. The final warranty scope follows the confirmed contract and supplied configuration.
