Hand-operated pressure grippers for curbs - SKOR Q/A1-A2

UNIMAN’s hand-operated pressure grippers are precision-engineered lifting and handling tools designed specifically for gripping, lifting and placing heavy objects such as curbs, blocks of concrete, granite or similar masonry materials. These grippers rely on a manual mechanism, where the operator activates the device by hand to clamp onto the load. Once engaged, the gripper transfers load-bearing force through a robust structural frame and gripping surfaces, enabling safe and controlled movement of heavy, awkward pieces. 

Key Advantages

  • Improved Safety & Control: Manually operated grippers allow the operator to feel the engagement and monitor the gripping action, reducing the risk of slippage or mis-clamp.
  • Versatility: These grippers are suitable for a range of heavy materials — including curb stones, concrete slabs and granite blocks — making them valuable for contractors, urban infrastructure works, and logistics operations. 
  • Reduced Manual Strain: By using mechanical advantage built into the gripper, the operator can handle much heavier loads than could reasonably be moved by hand alone, reducing physical exertion and potential injuries.
  • Precision Placement: Because the operator remains part of the process, the gripper system supports accurate placement of the load — crucial when setting curbs or blocks where alignments matter.
  • Durability & Professional Grade Design: We are specialists in lifting and handling equipment, exporting a large portion to Europe and Asia. The grippers are built for industrial work, meaning robust materials, engineered tolerances and suitability for regular use in demanding environments.
  • Simplified Logistics: Using a dedicated gripper means fewer ad-hoc rigging solutions and less improvisation. The right tool for the job (e.g., curb handling) means faster setups, fewer mistakes, and better throughput on job-sites.

How It’s Operated

In practice, the operator positions the gripper around the intended load (for example a curb unit or concrete block) such that the clamping jaws or pressure faces align with appropriate contact surfaces. The operator then exerts the manual activation (e.g., turning a lever, tightening a clamp or pumping a mechanical linkage) to apply pressure between the gripping faces and the load. This creates a secure hold via friction and/or mechanical engagement (depending on the model). Once the load is secured, the gripper can be attached to a lifting sling, crane hook, hoist or other lifting gear for movement. Because the gripper is hand-operated, the machine interface is simple and direct — the operator remains in control. On arrival at the destination, the manual release mechanism is used to disengage the gripper and safely set the load down.

Hand-Operated Pressure Grippers For Curbs- Adjustable

Uniman’s adjustable hand-operated pressure grippers for curbs are purpose-designed tools for gripping, lifting and precisely placing concrete curb units and similar masonry elements. These grippers feature an adjustable jaw or pressure face mechanism, enabling them to accommodate varying widths or profiles of curb blocks without compromising safety or efficiency. The hand-operation means the user manually engages the mechanism (often by lever, screw, or link-actuated clamp) to apply pressure to the load, securing it firmly. Uniman’s product line of “pressure grippers for curbs” is listed among their portfolio of lifting attachments for heavy materials.

How It’s Used

  1. Selection & Setup: The operator selects the correct gripper size and width-adjustment setting to match the curb section’s dimensions and shape. Because the gripper is adjustable, it can adapt to different widths or heights of curb blocks, reducing the need for multiple dedicated tools.
  2. Positioning: The gripper jaws or pressure faces are placed around (or against) the curb unit, aligning properly with flat contact surfaces, typically on the side or top faces of the block.
  3. Adjustment & Engagement: The operator uses the adjustment mechanism to set the jaw width (for example via sliding or screw adjustment), then manually activates the clamping action to apply pressure. This ensures a secure grip around the curb unit.
  4. Lifting & Moving: Once the load is secured, the gripper is connected to appropriate lifting gear (crane hook, hoist, sling etc.), and the curb unit is lifted, transported and placed into the required position (e.g., on site alongside roadworks or landscaping).
  5. Placement & Release: After accurate placement (where curb alignment and level are critical), the operator manually releases the grip, retracts the jaws/back off the pressure faces, and detaches the gripper from the block.

Because the gripper is adjustable and manually operated, the operator retains fine control over sizing, grip pressure and placement—making it suited to jobs where curb units vary slightly in size or when frequent change-over is required.

Key Advantages

  • Flexibility & Versatility: The adjustable width mechanism allows one tool to handle multiple curb sizes or different profiles, meaning fewer tools are needed on-site and quicker change-overs.
  • Safety & Secure Handling: The pressure-grip principle (rather than simple hook or lift-strap) provides a stable, controlled hold on heavy concrete elements. Uniman’s portfolio highlights “pressure grippers for curbs” as part of their safe-handling offering.
  • Precision Placement: Because the operator is hand-involved and the grip is rigid once engaged, the curb units can be placed with greater accuracy — crucial in roadworks or landscaping where alignment matters.
  • Reduced Manual Strain: While manually operated, the mechanical advantage built into the gripper means one operator can safely handle heavier loads than by purely manual methods.
  • Durable Industrial Design: As part of Uniman’s product range of lifting & gripping equipment, these grippers are built for heavy-duty use in construction environments.
  • Efficient On-Site Operation: Because the same adjustable tool can serve multiple curb sizes, setups, change-overs and inventories are simplified — improving job-site workflow and reducing downtime.

Hand-Operated Pressure Grippers For Tiles

UNIMAN’s hand-operated pressure grippers for tiles are purpose-engineered material-handling tools designed to grip, lift and accurately place heavy tile units—such as large ceramic, porcelain or natural stone tiles—safely and efficiently. These grippers operate via a manually-activated clamp or pressure mechanism: once positioned on the tile face (or edge, depending on model), the operator exerts the manual mechanism (lever, screw or linkage) to bring pressure faces into contact with the tile and secure the load. According to UNIMAN’s published product family, their pressure grippers are used for diverse materials including concrete, granite and blocks, indicating suitability for flat, rigid surfaces in heavy-duty applications

How It’s Used

  1. Selection & Setup: The operator identifies the correct gripper size/capacity for the tile load (weight, size, surface finish). Since tile panels vary in thickness and material, ensuring the pressure faces align properly and the grip range suits the tile is key.
  2. Positioning: The gripper is placed against the tile’s flat side or edge, aligning the pressure-faces so that adequate contact is made—flat surface of the tile and clean contact points improve grip.
  3. Engagement: The operator manually actuates the mechanism to apply pressure between the gripper’s jaws/pressure faces and the tile. When correctly engaged, the tile is held securely without relying solely on suction or adhesives.
  4. Lifting & Placement: With the tile secured, the gripper is used in conjunction with appropriate lifting gear (crane, hoist, forklift rigging) or hand-lifted if designed for lighter loads. The tile is moved and placed into its final position (e.g., on flooring, wall assembly, or façade installation).
  5. Release: After correct placement and alignment, the operator manually releases the gripper—retracting or loosening the clamping mechanism—and safely detaches the device from the tile surface.

Because the device is manually operated, the operator retains direct control throughout the process—allowing fine adjustments, careful placement, and immediate response to surface irregularities.

Key Advantages

  • Enhanced Safety & Control: A pressure-grip mechanism offers more reliable hold than makeshift clamps or plaster straps, reducing risk of tile slippage or damage during handling. UNIMAN’s portfolio highlights engineered pressure grippers for heavy materials.
  • Versatility: The gripper is designed for flat tile surfaces—ceramic, porcelain, natural stone—and can handle varying tile sizes (given the correct model/capacity). This makes it well-suited for installers, building contractors, and façade/tiling specialists.
  • Reduced Manual Strain & Labour: While hand-operated, the mechanical advantage built in means heavier tile units can be handled more safely compared to purely manual lifters or improvised methods.
  • Precision Placement: With direct operator control, the tool supports accurate placement of tile units—essential where alignment, level-setting and surface finish matter (e.g., large panels, architectural tiles).
  • Durable Professional-Grade Construction: As part of UNIMAN’s gripping-equipment range, the grippers are built for industrial environments, meaning robust materials, engineered tolerances, and suitability for frequent onsite use.
  • Streamlined Workflow: Using a dedicated tool means less improvisation on-site, fewer setup delays, and smoother transitions between tile units. This lends itself to improved productivity and fewer handling errors.

Hand-Operated Pressure Grippers For Circular Plates

UNIMAN’s hand-operated pressure grippers for circular plates are purpose-designed lifting and handling tools tailored to the safe, controlled manipulation of round or disc-shaped heavy loads, for example circular metal plates, flanges, embossings, large piping covers, steel discs, or similar items. The operation is manual: the tool features pressure faces / jaws which the operator manually engages (via lever, screw-mechanism or manual linkage) to press onto the surface of the plate and hold it securely. While UNIMAN’s catalog specifically mentions hand-operated grippers for cylindrical loads and “grippers for cylindrical surfaces / internal gripping” under the broader “grippers” product clusters.

How It's Operated

  1. Selection & Setup: The operator selects the correct gripper model and rated capacity matching: the diameter of the plate, its weight, surface finish (flatness, plating), and any tolerances. Because the load is circular, ensuring the pressure faces provide symmetric contact and the clearance/width of the jaws accommodates the plate diameter is important.
  2. Positioning: The gripper is placed such that the pressure faces or jaws contact the plate’s flat surface (or its edge) in a stable and even manner. The plate should be supported or resting as required until fully clamped.
  3. Engagement: The operator manually activates the mechanism (turns lever, tightens screw, or uses linkage) to bring the jaws/pressure surfaces into firm contact with the plate. Once the gripper is securely engaged, the plate is held with sufficient friction or mechanical grip such that it can be lifted, rotated, or moved without slippage.
  4. Lifting/Handling/Placement: With the plate secured, appropriate lifting gear (crane hook, hoist, sling, forklift or manually) can be used to move the plate to its destination — for example into position in a machine, onto a pedestal, or into an assembly line. Because the gripper is hand-operated, the operator retains direct control and can make small adjustments during movement.
  5. Release & Removal: Once the plate is correctly positioned and safely resting, the operator manually releases the clamp mechanism, backs off the pressure faces, and removes the gripper from the plate. The plate can then be locked or fastened into place if required.

Key Advantages

  • Precision & Control: Because the operator manually engages and monitors the grip, the system offers high control over placement and handling — critical for circular plates where orientation or alignment may matter (e.g., flanges with bolt-holes, decorative discs, steel plates).
  • Adapted to Circular Loads: The design is tailored for disc-shaped or round plates rather than standard rectangular blocks — meaning grip geometry, pressure face shape, clearance and support are optimized for circular profiles.
  • Improved Safety: Using a dedicated pressure-gripper avoids unsafe ad-hoc methods (slings under plates, cantilevered lifts) and reduces risk of slippage or uncontrolled movement. UNIMAN’s product line emphasises safe handling in heavy-duty settings.
  • Reduced Manual Strain: While manually operated, the mechanical design (leverage, structural rigidity) allows operators to handle heavier plates than they could by hand alone or via manual lifting, thereby reducing physical strain and improving ergonomics.
  • Durable Industrial Construction: As part of UNIMAN’s specialized gripping equipment portfolio, the product is engineered for rigorous industrial use (construction, steelworks, heavy manufacturing).
  • Versatility for Plate Sizes: Although specific geometry must match the application, the tool concept allows handling of varying diameters (within the model’s rated range) of circular plates, reducing the need for multiple custom tools for each plate size.
  • Better Workflow Efficiency: Using a purpose-designed gripper for circular plates can streamline handling operations: faster setup, fewer manual adjustments, reduced handling errors, and improved productivity on site or in the factory.
