Load cell

V.W. Load Cell is designed to measure load working on earth anchor. Rated Capacities

Customized for 100~150 tons, 200 tons or higher Over Range Capacity 150% F.S Sensitivity

±0.025% Accuracy ±0.025% to ±0.5% Temperature Range -20? ~ +80?

CONFIGURATION AND OPERATING PRINCIPLE

PURPOSE

- Prolonged Monitoring changes in loads on anchor by excavation.

- Measuring the temporary tension in cable installed part of bridges.

- Checking the stability and evaluating the effectiveness of support system such as retaining wall,

earth anchor.

- Earth Anchor Method, Prolonged Monitoring Axial load on V.W Rock Bolt.

- Made as High Strength waterproof type and well-used for file test.

HOW TO INSTALL

1. When installing in Earth Anchor, process the wale in advance according to the Load Cell standard.

(To prevent Flange of wale and strain of Web, you should install Stiffener.)

2. Connect the Cable and then record zero using measuring instruments.

3. Place bottom loading plate, load cell, top loading plate and distribution plate in order on the

Processed wale to be vertical to Anchor.

At this point, note that Anchor line should not reach to the wale or cell.

4. After pulling with Expected Axial load using stress tensile machine, install Anchor.

At this point, note that eccentric should not be on Load Cell, to minimize the loss of Prestress,

if using Oil Jack, insert male cones after several hours (Soil : 5min., Rock : 2min.) under the

maximum pressure.

5. When pulling, measure the stretched amount and check the status of Earth Anchor by

comparing with the planned amount
