Material Shear Testing Machine
Premium & Durable Material Construction
We adopt high-grade industrial metal raw materials for every component of this soil direct shear tester to guarantee long service life under frequent lab testing:
1. Main support frame: Thickened carbon steel plate with anti-rust matte black spray coating, anti-corrosion, anti-deformation, stable structure without shaking under long-time repeated vertical pressure loading.
2. Shear box & transmission assembly: Precision cast alloy steel, high hardness, wear-resistant, no deformation after thousands of soil shear tests.
3. Weights, pressure levers and force measuring components: Solid cast iron with anti-oxidation treatment, stable gravity loading without weight loss or deformation.
4. Dial gauge and control motor shell: High-strength aluminum alloy, dust-proof and anti-collision, suitable for dusty construction testing labs. All metal parts go through pickling, rust removal and multi-layer paint spraying processes, effectively resisting oxidation and moisture erosion in humid geotechnical laboratories.
Outstanding Functional Advantages
1. Dual adjustable shear speeds: Built-in two standard shear rates (0.8mm/min fast shear & 0.06mm/min slow consolidated shear), fully meet global geotechnical test standard requirements, stable constant strain loading with no speed fluctuation.
2. Counterweight gravity vertical pressurization system: Manual weight stacking applies uniform normal stress to soil samples, no hydraulic oil leakage trouble, lower failure rate and maintenance cost than hydraulic shear equipment.
3. High-precision dial force measurement: High-sensitivity mechanical dial gauge captures real-time shear force data, clear readings, excellent data repeatability for consistent test results.
4. Mature mechanical transmission design: Stable gear drive structure, simple operation logic, few vulnerable parts, easy calibration and daily maintenance for lab staff without professional electrical skills.
5. Standard matching structure: Fits standard 61.8mm circular soil sample cutting rings and shear boxes, perfectly compatible with conventional soil sample preparation tools. Optional digital display module can be upgraded to replace traditional dial gauge for automatic data reading.
Wide Application Scenarios
This strain-controlled direct shear apparatus is a basic essential instrument for geotechnical mechanics testing, widely applied in multiple industries worldwide:
● Highway & Railway Engineering Labs: Test subgrade and embankment soil to calculate slope anti-sliding stability for road construction acceptance.
● Water Conservancy & Hydropower Institutions: Conduct shear tests on dam, river dike foundation soil to support hydraulic engineering design and safety evaluation.
● Third-Party Construction Inspection Organizations: Complete routine foundation soil sampling inspection for building project quality acceptance.
● University Civil & Geological Engineering Labs: Standard soil mechanics teaching experimental equipment for student operation training and academic research.
● Construction Supervision & Municipal Testing Stations: On-site soil quality detection for residential buildings, municipal roads and infrastructure projects.
Comprehensive After-Sales Support
1. 12-month full machine warranty: Free replacement for damaged motor, transmission gears, dial gauge and metal structural parts within warranty period (consumable shear box excluded).
2. 24-hour online remote technical service: Professional engineer team provides one-on-one video guidance for equipment calibration, operation training and troubleshooting at any time.
3. Complete free training documents: Standard English operation manuals, step-by-step test operation videos and geotechnical test standard guidance documents provided together with each shipment.
4. Lifelong cost-price spare parts supply: After warranty expiration, all replacement accessories (shear box, dial gauge, transmission weights, gears) are supplied at factory cost price with no extra service fees.
5. Customized technical support: We offer voltage conversion, digital module upgrade and multi-language operation guide customization according to different country market demands. For full container bulk orders, overseas on-site installation and operator training service is available.
Heavy-Duty & Reinforced Shipping Packaging
We design export-grade anti-collision packaging to ensure intact equipment delivery to global customers:
1. Internal protection: All precision parts (dial gauge, shear box, motor) are wrapped with shockproof bubble film and fixed by customized foam mold to avoid collision scratches and component displacement during long-distance sea transportation.
2. Outer packaging: Thick solid plywood export wooden case with internal reinforced steel frame, moisture-proof plastic film fully wrapped inside the box to resist sea moisture and rain erosion.
3. Fastening design: Metal lock buckles and steel binding straps fix the wooden case tightly; bottom skid design supports forklift loading and unloading without case breakage.
4. Separate accessory packing: Small spare parts, weights and tools are packed in independent small anti-rust metal boxes, marked with clear English labels to prevent loss during transit. All packaging passes drop and vibration testing to adapt long sea freight and multi-times loading & unloading, effectively eliminating damage risks during international logistics.
FAQ
Q1: What Soil Samples Is This ZJ-1A Direct Shear Tester Applicable To?
A: It is specially designed for fine-grained soil, clay, silt and fine sand samples. For coarse gravel and rockfill soil tests, we recommend our large coarse-grained soil triaxial shear testing machine separately.
Q2: What Two Shear Speeds Does This Machine Support? Are Custom Speeds Available?
A: Standard dual speeds: 0.8mm/min for fast shear test and 0.06mm/min for slow consolidated shear test to match mainstream geotechnical standards. Custom single-speed models can be produced upon your order requirements.
Q3: Is The Packaging Strong Enough For Long-Distance Sea Shipping?
A: Absolutely. We use reinforced export plywood wooden cases with shockproof foam internal lining, moisture-proof film and steel binding straps. All precision measuring parts are fixed by customized foam molds to avoid collision damage during sea and land transit.
Q4: What Core Soil Mechanical Indicators Can We Obtain After The Shear Test?
A: After finishing the test and data calculation, you can get two key parameters: soil cohesion (c) and internal friction angle (φ), which are core data for foundation settlement and slope stability engineering design.
Q5: What After-Sales Technical Help Can I Get After Purchasing This Machine?
A: We provide 1-year full machine warranty and 24-hour remote video technical support. Free English operation manuals and training videos are attached to each order. Spare parts are supplied at factory cost for lifelong maintenance after the warranty period expires.
