Conventional Electric Wrench

BOSI's Conventional Electric Wrench series offers multiple torque levels to meet various needs, from light tire disassembly and assembly to heavy-duty steel structure bolt tightening. The entire series features an ergonomic design for comfortable grip; forward/reverse switches for easy operation; and efficient heat dissipation for longer service life.

300W power models (12C/16C/20C) have a torque of 150-250 N·m, suitable for passenger car tires and mechanical assembly.

600W models (24C) have a torque of 500 N·m, suitable for truck tires and heavy equipment.

1050W models (36C) have a torque of 1100 N·m, suitable for high-torque operations such as bridge and steel structure work.

Spindle sizes range from 1/2 inches to 1 inch, accommodating different sleeves.

Product Specifications

*Common parameters: Rated voltage 220V~ / 50Hz, forward/reverse switch, ergonomic design, efficient heat dissipation*

Product Advantages

Multiple torque options: 150 N·m suitable for small passenger car tires; 250 N·m suitable for SUVs and light trucks; 500 N·m suitable for heavy trucks and construction machinery; 1100 N·m suitable for high-strength bolts in bridge steel structures, etc.

Forward/Reverse Switch: Quickly switch between tightening and untightening modes to improve work efficiency.

Ergonomic Handle: Comfortable grip, no fatigue during long-term operation; balanced center of gravity reduces wrist strain.

High-Efficiency Heat Dissipation: Built-in fan and optimized airflow prevent overheating during continuous high-torque operation.

High-power motor: 36C model 1050W, output torque 1100 N·m, easily removes and installs M36 rusted bolts.

Spindle size standards: 1/2 inch for common sleeves; 3/4 inch and 1 inch for large sleeves, highly versatile.

Actual Use Cases

On bridge construction sites, when tightening M30 high-strength bolts (torque requirement 900 N·m), the previously used hydraulic wrenches were inefficient and bulky.

The BOSI 36C Conventional Electric Wrench (1100 N·m) is relatively lightweight, easy for single-person operation; it provides sufficient torque for a single tightening; and it allows for quick forward and reverse switching, making disassembly equally efficient.

It can tighten more than 200 bolts per day, three times more efficient than hydraulic wrenches. Meanwhile, the 24C model is used for disassembling and assembling M20 bolts on temporary on-site supports; 500 N·m is sufficient and it is even lighter.
