Master Massive Bolting Projects: The Ultimate Crawler-Mounted Tightening Machine for Demanding Industrial Applications

Beyond Basic Tightening: Precision Engineered Intelligence

Our crawler system isn’t just powerful—it’s smart. Here’s how it revolutionizes critical bolting:

1. Ultra-Precise Control & Monitoring

   • Real-time dynamic display of torque/angle values with visual process graphics

   • ±3% torque accuracy & ±1° angle precision

   • False torque detection to prevent assembly failures

   • Zero-drift compensation for sensor integrity

2. Military-Grade Process Flexibility

   • Multi-stage tightening: Pre-tighten → Transition → Final torque with independent speed control

   • 7+ Control Modes: Torque-only, Angle-only, Torque+Angle, Angle+Torque monitoring

   • Advanced sequencing: Simultaneous, asynchronous, or sequential bolting with zero-speed hold

3. Self-Diagnosing & Error-Proof Operation

   • Automatic socket engagement/disengagement (no manual handling)

   • Fault autodiagnosis with audible/visual alarms (≤70 dB operational noise)

   • Smart error recovery: Auto-reverse & re-tighten failures with one reset

4. Engineered for Real-World Reliability

   • Triple-Layer Protection:

     • Process: Torque/angle upper/lower limits

     • Hardware: Overload/overvoltage/overspeed cutoffs

     • Software: Watchdog timers + digital filtering

   • Industrial-Grade Immunity:

     • LAPP® shielded cables + optical isolation

     • Servo signal filtering + isolation transformers

5. Operator-Optimized Workflow

   • 10" Touchscreen HMI with intuitive Chinese UI

   • One-touch program switching for mixed production

   • Live graphical torque/angle curves + pass/fail indicators

   • Jog control + automatic cycling per axis

Why This Beats Traditional Solutions

"While stationary machines struggle with large structures, our crawler delivers surgical precision where you need it. The combination of 150 N.m torque, adaptive sequencing, and MIL-spec EMI hardening makes this the only solution for bridge girders, wind turbine flanges, or shipyard megaprojects."

Ideal For:

• Wind tower assembly

• Mining equipment maintenance

• Structural steel construction

• Heavy machinery manufacturing
