LT-JJ02-B Office Chair Armrest and Back Tester Machine

Why Choose the LT-JJ02-B for Your Furniture Testing Lab?

Unlike single-function testers, the LT-JJ02-B is a multifunctional powerhouse. It is specifically designed to evaluate the strength and durability of two critical components: the armrest and the backrest.

Key Advantages:

· Dual Testing Capability: Seamlessly switch between testing armrest compression strength and backrest pressure resistance.

· Smart Control System: Equipped with a PLC (Programmable Logic Controller) and a touch screen interface. This ensures accurate data logging and allows for easy operation.

· Safety First: Features like power-off memory and breakpoint stop functions ensure that your tests are never compromised by unexpected outages, and the machine stops immediately if a sample breaks.

Key Features of the LT-JJ02-B Armrest & Back Tester

What sets the LT-JJ02-B apart from standard testing equipment is its intelligent design and robust construction.

· Precision Pneumatics: The machine utilizes imported SMC precision pressure regulators. This allows for stable force output, and the digital display lets you monitor the exact pressure being applied in real-time.

· Adjustable Geometry: The angle of the cylinder can be adjusted by sliding the pulley position. This flexibility allows the machine to adapt to various chair designs and test angles (e.g., simulating the force applied when a user leans back or presses down on the arm).

· Robust Fixturing: It comes with standard configuration accessories, including armrest loading fixtures and backrest loading pads, ensuring that your samples are held securely during high-stress tests.

Technical Specifications of the LT-JJ02-B Model

For engineers and procurement managers, having the exact specifications is crucial for lab planning. Here is the technical data for the LT-JJ02-B:

Note: The machine has a power rating of 0.4KW and requires a stable air source for optimal performance.

How the LT-JJ02-B Works: Testing Procedures Explained

The LT-JJ02-B Office Chair Tester operates by simulating real-world abuse and usage.

1. Armrest Strength Test: The machine applies a vertical or horizontal load (ranging from 50Lb to 300Lb) to the armrest to assess its ability to handle weight without cracking or detaching.

2. Backrest Strength Test: It simulates a user leaning back by applying a controlled pressure (up to 1334N or 300Lb for destructive testing) to the backrest. The loading pad is secured to the backrest, connected via a strap to the cylinder, allowing the chair to naturally rebound after the force is released.

The touch screen + PLC system allows you to set the frequency (5-30 times per minute) and the total number of cycles, providing a comprehensive fatigue analysis.
