Overview
RUNJIE RJ-5 miniature drawing instrument is a bolt tension gauge, which is suitable for bolt, anchor cable, steel bar, bolt and other anchorage force detection. It is one of the instruments required for mass inspection of bolt construction support engineering. The instrument is composed of manual pump, hydraulic cylinder, digital pressure gauge and high voltage hose, anchor, tie rod, adapter, portable box and other parts. The structure is compact, easy to carry, small size and light weight. The pump body is made of precision cast steel, which has a long service life; the hydraulic cylinder is hollow self-reset type; the digital pressure gauge reads intuitively, can directly read the bolt tension value, and has automatic calculation, backlight, peak holding, storage and query functions. The manual pump can also be used as a power source for general small Flow rate high voltage oil.
Features
1. Nickel Plated Pistons and Slides
2. With Data storage function, 100 Data storage capacity
3. Surface corrosion electrostatic spray
4. New sealing ring, reliable work
5. Instrument data query and deletion
6. Automatic spring return, simple structure
7. Automatic shutdown function
8. Peak hold function
Principle
The RJ-5 bolt tension gauge generates high voltage oil through a manual pump, which is transmitted to the hydraulic cylinder through the high voltage hose, drives the piston to generate tension, and acts on the anchor and other anchors to detect the anchoring force. The digital pressure gauge displays the tension value in real time, and has the functions of automatic calculation, peak holding and Data storage. The hydraulic cylinder adopts a hollow self-reset design, which is easy and reliable to operate.
Applications
Anchorage force test of bolt, anchor cable, steel bar, bolt and other anchorage bodies, mass inspection of bolt construction support engineering

Steps
1. Connect manual pump, hydraulic cylinder and digital pressure gauge
2. Install anchors, tie rods and adapters
3. Start the manual pump to apply pressure
4. Observe the digital pressure gauge reading
5. Record or store inspection data
6. Unloading reset after the operation is completed
Notice
• Check whether the connection of each part is firm before use
• Ensure that the digital pressure gauge battery is fully charged
• Pay attention to safety during operation and avoid overpressure use
• Regular maintenance of sealing ring and hydraulic system
Be aware of capacity limitations when storing data
