Aluminum titanium alloy drive hollow hydraulic torque wrench is composed of a power head and a working head. It adopts aluminum-titanium alloy material and an integrally molded body to comprehensively strengthen the strength and toughness of the fuselage. It can be used for multiple purposes in one machine. One power head can be equipped with multiple working heads, and the working range is wide. 
 
1. Aluminum-titanium alloy one-piece body: double guarantee of strength and toughness
Material advantages:
Aluminum-titanium alloy has both high strength (tensile strength comparable to 45 steel) and light weight (density is only 36% of steel), and can still maintain stability at high temperatures of 450-500℃. Its corrosion resistance is better than that of traditional steel wrenches, and it is especially suitable for humid or marine environments.
One-piece molding process:
The body is integrated through precision forging or CNC processing, eliminating welding seams, improving the overall structural strength and fatigue resistance, and avoiding the risk of deformation or breakage during long-term use.



2. 360°X180° swivel joint + high-precision ratchet: a tool for working in narrow spaces
Flexible positioning:
The swivel joint supports 360° axial and 180° radial rotation, and can bypass obstacles for multi-angle operation, solving the problem of working in narrow spaces (such as pipe flange gaps).
Torque accuracy:
The precision ratchet mechanism is used to achieve a torque accuracy of ±3% through tooth number optimization and friction control, ensuring that the bolt preload meets the specifications and reducing the risk of leakage.



3. Modular design: one machine for multiple uses, efficient switching
Separation of power head and working head:
The power head (including hydraulic pump interface) and working head (including sleeve) are connected through a quick interface, supporting multiple specifications of working heads to share the same power head, reducing the number of tools and reducing maintenance costs.
Application scenarios:
Applicable to pre-tightening operations from M16 to M64 bolts. By replacing the sleeve, different specifications can be covered to improve equipment utilization.



4. Retractable drive shaft and sleeve: the ultimate fit for compact space
Retractable design:
The drive shaft length is adjustable, and with sleeves of different depths, it can adapt to the change in the extension length of the bolt, especially in the equipment or double nut scenarios.
Metric/imperial compatibility:
Supports both millimeter and inch standards to meet the mixed use requirements of international standard bolts and improve the compatibility of tools for global operations.
 
5. Customized locking drive shaft: Accurately match user working conditions
Customized service:
Design a dedicated drive shaft length, diameter and locking mechanism according to the bolt specifications, space restrictions and operating angles provided by the user to ensure torque transmission efficiency.
Case application:
In the maintenance of nuclear power equipment, ultra-thin drive shafts are customized to fit the bolts in the radiation shielding layer. The thickness is reduced by 40% and the torque stability can be maintained.
6. Mobile handle: balance between portability and maneuverability
Ergonomic design:
The handle adopts a lightweight alloy frame, the surface is covered with non-slip silicone, and the center of gravity is optimized to reduce operator fatigue.
Quick mobility:
Integrated rollers or folding brackets (optional) support a single person to quickly transfer tools in complex construction sites, improving multi-station operation efficiency.

Hollow hydraulic torque wrench is suitable for places with narrow spaces. It is applicable to electric power (nuclear power, wind power, hydropower, thermal power), ships, metallurgy, transportation, cement, construction, aviation, and other fields.
