Description
Model: HG5TW | Series: HGTW | Product Line: Industrial Tools
-
Maintenance-Free Brushless Motor: Powered by a brushless motor that requires no maintenance, the HGTW Series delivers quiet, reliable operation with extended service life—minimizing downtime and reducing long-term operating costs.
-
Integrated Cable Management: The integrated frame design features a built-in cable winder, allowing for convenient and organized control cable storage between uses, reducing clutter and protecting cables from damage.
-
Tool-Free Pressure Gauge Exchange: The pressure gauge is designed for quick, tool-free installation and removal, simplifying maintenance and enabling fast replacement when needed.
-
Multi-Tool Simultaneous Operation: Standard configurations offer two-way or four-way outputs, allowing a single pump to drive multiple hydraulic torque wrenches simultaneously—enhancing productivity on large-scale bolting projects.
-
Automatic Solenoid Air Vent Valve: Equipped with an electromagnetic automatic air vent valve that activates upon power-up, ensuring automatic intake and exhaust functions for efficient system priming and reliable operation.
-
High-Efficiency Air Cooling: Features a high-performance air-cooled radiator that effectively dissipates heat during continuous operation, maintaining optimal hydraulic fluid temperatures and ensuring consistent pump performance over extended work cycles.
-
Optional Digital Control Handle: Optional R2/R4 model digital control handles are available, enabling operators to monitor real-time pressure values directly from the handle for enhanced visibility and control during tightening operations.
-
Lightweight Aluminum Reservoir: The hydraulic oil reservoir is constructed from aluminum, offering lightweight properties combined with excellent heat dissipation for improved thermal management and reduced overall unit weight.
