Electric rebar coupler torque wrench main Components
Working Principle
Powered by a built-in electric motor, the wrench drives the hardened gear teeth to rotate and engage the coupler, securely connecting rebars with high efficiency.The motor uses a brushless permanent-magnet motor,Its advantages are:
- High Efficiency:Meets the highest international IE4/IE5 efficiency levels; performance is 15 % higher than that of a brushed motor, with even greater gains under heavy load.
- Fast Payback on Energy Savings:Replaces brushed motors and cuts system energy use by up to 30 %, giving longer run-time on the same battery charge.
- Cooler Running:Winding temperature rise is 20 K lower than in a brushed motor, so the machine can run for hours without risk of burn-out.
Multi purpose machine:
1、Electric steel bar coupling torque wrench for transverse installation of steel bars:

Twisted steel bars—compatible with straight-thread rebar from 16 mm to 40 mm diameter.

Screwing the straight threaded rebar coupler-it can clamp an inner diameter of 16–36 mm (outer diameter of the sleeve: 19–53 mm).
2、Electric steel bar coupling torque wrench for vertical installation of steel bars:

Twisted steel bars—compatible with straight-thread rebar from 16 mm to 40 mm diameter.

Screwing the straight threaded rebar coupler-it can clamp an inner diameter of 16–36 mm (outer diameter of the sleeve: 19–53 mm).
Advantages over Traditional Tools:
Significantly higher efficiency vs. manual or pipe wrench methods.
Reduction in labor cost and manual fatigue.
Suitable for heavy-duty construction applications such as bridges, high-rise buildings, tunnels, precast elements.
One-button operation simplifies use and reduces error risk.
Applications
Mechanical connection of rebars using couplers.
Construction projects requiring high-strength reinforcement assembly.
Situations where speed, precision, and durability are essential.
