The core design follows the principle of &#8220;three-point support auxiliary support,&#8221; combined with adjustable feet and vibration\/isolation measures, to prevent platform deformation and vibration nterference. The following are the classification, structure, selection, and installation key points of the system:<\/p>\n\n\n\n<p>I. Mainstream Types and Structures<br>Welded Steel Frame Stands (Indust General Use)<br>Material: Welded square steel\/steel channel, annealed to relieve stress; surface powder coating for rust prevention<br>Support Method: Standard 3-mainxiliary five-point support (3 main points form a stable triangle, 2 auxiliary points prevent warping, non-load-bearing)<br>Adjustment: Bottom equipped with heavy-duty adjustable leveing feet (M20 and above); top often features spherical joints nylon\/PTEE washers (to prevent metal electrochemical corrosion and fine-tune angle)<br>Application: Medium to large latforms (1000\u00d71000mm and above), CMM measurement, precision inspection<\/p>\n\n\n\n<p>Column-type \/ Split Stands (Small to Medium Platforms)<br>Structure: Independent adjusta columns, no need for a whole frame; some feature cast iron bases steel columns<br>Advantages: Small footprint, fast installation, expandable on demand<br>Application: Laboratories, small inspecon benches (400\u00d7400~800\u00d7800mm)<\/p>\n\n\n\n<p>Air-bearing \/ Vibration Isolation Stands (Ultra-precision Scenarios)<br>Config Air springs\/air pads, capable of isolating ground vibrations (frequency 2~20Hz), combined with an automatic leveling system<br>Precision: Suitable for Grade 0rms, optical measurement, nanoscale detection; higher price<\/p>\n\n\n\n<p>Simple L-type \/ Wall-mounted Stands (Civilian \/ Light Tooling)<br>Usage: Stone countertops, small ches; mostly pressed\/welded metal parts, fixed to walls or bases<\/p>\n\n\n\n<p>Granite Worktop Stands<\/p>\n\n\n\n<p>II. Key Technical Parameters and Selection Criteria<br>Load and Platform Siz The stand&#8217;s rated load capacity must be &gt; platform self-weight maximum workpiece\/equipment weight; for large platforms (&gt;2000mm), prioritize welded frames five-point sort<br>Leveling Adjustment Range: Adjustable foot travel is usually 15~30mm, meeting ground unevenness of \u00b110mm; after leveling, confirm with an electronic evel; Grade 00 platform levelness \u22640.005mm\/m<br>Material and Corrosion Resistance: Carbon steel stands require powder coating\/galvanization; direct rital clamping against granite is strictly prohibited; insulating washers (e.g., nylon, rubber) must be added<br>Vibration Control: Select rigid stands for ordinary workshops; opticnd metrology rooms must be equipped with vibration isolation pads\/air-bearing systems<\/p>\n\n\n\n<p>III. Installation and Leveling Steps<br>Ground Pre-treatment: Concrete floor strength C25 flatness \u22642mm\/m; secondary grouting foundation if necessary<br>Position the stand, roughly level the three main supports first, then gently place the granite platform<br>Fine-tune with an elecel following the sequence &#8220;corners first then center, longitudinal first then transverse&#8221;; each micro-adjustment \u22641mm, wait 5 minutes after adjustment before measuring again<br>Lock eveling feet, auxiliary points should gently contact (must not be jammed); finally re-measure flatness and levelness<\/p>\n\n\n\n<p>IV. Common Standards and Maintenance<br>Relevant Stadards: GB\/T 22095 &#8220;Rock Plates&#8221;, JJG 117 &#8220;Plate Verification Regulations&#8221;<br>Maintenance: Regularly check if leveling feet are loose; avoid long-tee-sided overloading of the stand; when environmental humidity &gt; 60%, additional rust prevention treatment is required for the s<\/p>\n\n\n\n<p><strong>Granite\u00a0Platform Bracket Selection Quick Reference Table<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td>Sc\u00e9nario d'application<\/td><td>Type de support recommand\u00e9<\/td><td>M\u00e9thode de soutien<\/td><td>Exigences suppl\u00e9mentaires<\/td><\/tr><tr><td>Mesure des coordonn\u00e9es (1500\u00d72000mm)<\/td><td>Support de cadre soud\u00e9<\/td><td>3 principaux + 2 auxiliaires Soutien en cinq points<\/td><td>Pied r\u00e9glable + articulation sph\u00e9rique + coussin en nylon<\/td><\/tr><tr><td>Grade de laboratoire 00 Petite plate-forme<\/td><td>Support de colonne divis\u00e9e<\/td><td>Soutien en trois points<\/td><td>\u00c9quip\u00e9 d'un coussin d'isolation contre les vibrations<\/td><\/tr><tr><td>Inspection optique\/Mesure nanom\u00e9trique<\/td><td>Support flottant pneumatique d'isolation des vibrations<\/td><td>Positionnement en trois points + mise \u00e0 niveau automatique<\/td><td>Taux d'isolation vibratoire \uff1e 90%<\/td><\/tr><tr><td>Inspection de routine en atelier<\/td><td>Support de cadre en acier \u00e0 section simplifi\u00e9e<\/td><td>Soutien en cinq points<\/td><td>Spray plastique antirouille<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img alt=\"\" fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/jtlcnc.com\/wp-content\/uploads\/2026\/01\/\u652f\u67b63-1024x768.jpg\" class=\"wp-image-1244\" srcset=\"https:\/\/jtlcnc.com\/wp-content\/uploads\/2026\/01\/\u652f\u67b63-1024x768.jpg 1024w, https:\/\/jtlcnc.com\/wp-content\/uploads\/2026\/01\/\u652f\u67b63-300x225.jpg 300w, https:\/\/jtlcnc.com\/wp-content\/uploads\/2026\/01\/\u652f\u67b63-768x576.jpg 768w, https:\/\/jtlcnc.com\/wp-content\/uploads\/2026\/01\/\u652f\u67b63-16x12.jpg 16w, https:\/\/jtlcnc.com\/wp-content\/uploads\/2026\/01\/\u652f\u67b63-800x600.jpg 800w, https:\/\/jtlcnc.com\/wp-content\/uploads\/2026\/01\/\u652f\u67b63.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>","protected":false},"excerpt":{"rendered":"<p>Les plates-formes de granit sont des structures sp\u00e9cialis\u00e9es utilis\u00e9es pour les mesures de pr\u00e9cision et l'usinage afin de soutenir les plaques de granit et d'en assurer la plan\u00e9it\u00e9 et la stabilit\u00e9.
