PPD-Horizontal Plate Clamp Features:

• Horizontal clamping, different forces. Adopting the "horizontal clamping surface + lateral positioning block" design, the clamping force is perpendicular to the surface of the plate (CDH is parallel to the edge), the contact area is 60% larger than CDH (8-ton contact area ≥ 200cm²), and the pressure per unit area is reduced by 40%, which is suitable for thin and brittle plates (such as 5mm aluminum plates) to avoid deformation. The spacing of the lateral positioning blocks can be adjusted (50-300mm) to prevent the plate from slipping when hoisting horizontally, and the probability of slipping is ≤0.5% (CDH has no risk of slipping when hoisting vertically, but the edge is vulnerable).

• Self-locking structure, easy to operate. No need to manually adjust the screw (different frm the active clamping of CDH), using the principle of "gravity self-tightening": when lifting, the gravity of the plate drives the clamp to automatically tighten the upper pressure block, and the clamping force increases with the load (clamping force ≥20kN at 8 tons load), saving 50% clamping time compared to manual adjustment of CDH (15 seconds for one person to complete clamping). When loosening, just slightly lower the plate, and the self-tightening device will automatically unlock, which is suitable for frequent loading and unloading scenes.

• Lightweight adaptation, flexible scene. The main body adopts a hollow design, the 8-ton weight is about 12kg (CDH 8-ton weight is about 15kg), and one person can carry and install it. The clamping height is low (≤150mm), which is suitable for the bottom lifting of stacked plates (such as steel plates stacked in warehouses, without reserving edge space), while the CDH vertical plate clamp requires the plate edge to be exposed ≥100mm, which is limited in dense stacking scenes.

• Optimized protection, diverse adaptability. The contact surface of the clamp is inlaid with rubber pads (hardness 60 Shore A), which is more suitable for smooth surface plates (such as mirror stainless steel plates) than the metal clamp teeth of CDH to avoid scratches; the main body is galvanized + spray-coated, salt spray resistant for 600 hours (CDH is 800 hours), suitable for general industrial environments, and the price is 20%-25% lower than the CDH with the same load.

PPD-Horizontal Plate Clamp Typical Applications:

• Workshop plate transfer. Horizontal handling of 2-5mm thin steel plates (3-5 tons) in mechanical workshops. The large area clamping of PPD prevents thin plates from bending and deformation. The self-tightening structure quickly completes the transfer from the shelf to the machine tool, and the hourly efficiency is 30% higher than CDH (CDH needs to align the edges, and thin plates are easy to get stuck); handling of glass fiber reinforced plastic plates before processing (1-3 tons), rubber pad protection to prevent surface scratches, and horizontal clamping to adapt to the feeding direction of the cutting machine.

• Warehouse stacking operation. Steel warehouses stack 10-20mm thick steel plates (5-8 tons), PPD can directly clamp and lift from the bottom layer (no need to move the upper plate), and the lateral positioning block ensures neat stacking (deviation ≤5mm); multi-layer handling of aluminum plate warehouses, lightweight design allows forklift drivers to operate alone, saving 1 auxiliary worker compared to CDH, reducing labor costs.

• Building board installation. Horizontally install roof panels (2-4 tons) in steel structure workshops. PPD clamps the panels and hoists them horizontally to the roof. Rubber pads prevent coating wear. Self-tightening structures allow for quick loading and unloading at high altitudes. Horizontally dock precast concrete panels (3-6 tons). The clamping surface does not damage the panel surface and is suitable for the rough environment of construction.
