How to install the slab racks? 1.Prepare the Site Ensure the installation area is flat, level, and has enough space (clear of obstacles). Check the ground bearing capacity to support the rack’s weight (plus stone loads). 2.Assemble the Base Frame Connect the bottom horizontal beams (the main base structure) using bolts or fasteners, ensuring it’s square and stable. 3.Install Vertical Posts Align the vertical posts (the tall poles) with the pre-drilled holes on the base frame. Secure them tightly with screws/bolts—make sure posts are vertical (use a level for adjustment). 4.Add Intermediate Beams (if applicable) Attach the middle horizontal beam (the secondary support layer) to the vertical posts at the designed height, locking it in place to reinforce stability. 5.Final Inspection Check all connections for tightness; confirm the entire rack is level and stable before loading stone slabs.

What is a Marble Clamp? A marble clamp (often referred to as a slab lifting clamp or carry clamp) is a mechanical device used to grip and lift large, flat pieces of stone. Unlike standard wood clamps, these are engineered for gravity-assisted grip. They typically feature: Scissor Action: A mechanism that uses the weight of the stone to increase the clamping force. Rubber Lining: Vulcanized rubber pads that provide high friction while preventing the stone from scratching or chipping. Ergonomic Handles: Designed for two-person carries to distribute weight evenly and protect the back. Key Types of Marble Clamps Depending on the stage of the project—moving the slab or joining it—different clamps are required: Type Purpose Key Feature Carry Clamps Moving slabs manually between locations. Sold in pairs; uses body weight to secure the grip. Lifting Clamps Attaching to a crane or forklift to move full slabs. High weight capacity (often up to 1,000+ kg). Seam Setters Joining two pieces of stone (e.g., a countertop seam). Uses suction cups and leveling dials for a flush finish. Mitre Clamps Holding 45-degree edges together while glue cures. Ensures perfect 90-degree corners on "waterfall" edges. Why Use Specialized Clamps? Using the wrong tool for stone is a recipe for disaster. Marble clamps provide three critical advantages: Safety: Carrying a 3 cm thick granite slab by hand is incredibly difficult. The polished surface offers no natural grip. Clamps provide a secure handle, reducing the risk of drops. Pressure Distribution: Stone is strong under compression but weak under tension. Marble clamps are designed to apply pressure evenly, preventing "point loading" that can cause a slab to crack. Efficiency: A pair of high-quality carry clamps allows two people to move pieces that would otherwise require four, saving time and labor costs. Pro-Tips for Using Marble Clamps Keep it Clean: Dust and stone slurry can act like ball bearings between the clamp and the stone. Always wipe the contact points and the rubber pads before lifting. Check the Rating: Every clamp has a Working Load Limit (WLL). Never exceed it. A standard 2 cm marble slab weighs roughly 13lbs per square foot; always do the math before you lift. Vertical is Best: Most carry clamps are designed for vertical transport. Attempting to lift a slab horizontally ("flat") with a vertical clamp can cause the stone to snap under its own weight.

3pcs slab clamps delivered to Italy by UPS, expensive courier freight almost catches up with the clamps value. "The clamps are deserved  and we can receive them within one week "  said by the customer who's not first time decide to ship by courier. Why some customers would like to pay high freight for a clamp that's value is not high?  Hetai is not only a factory but also do exprot, we have big stock of regular products, we have price advantage, we have long relationship agents for different shipping way, customers just wait for the goods, no need to worry about too much.

Technicians are in client's factory for a new machine installation and debugging today.  It is one of the leading diamond tools manufacturers in China and the brand is well-known overseas, supplying mainly wire saws for quarrying, profiling, slab cutting and reinforced concrete cutting. As one of our old friends and important client,  this is not the first 30-meter multi wire saw sharpening machine from HETAI,  even not only multi wire saw grinding machines from HETAI. Their operators are already familiar with the machines and satisfied with the performance of our machines. It's hot in July and the temperature will last till August, hope our client's business is hot and prosperous like the summer wether.
