INTRODUCTIONS

            Lifting clamps, as a kind of operating lifting tool which made of high quality low carbon steel alloy are designed for safe and simple lifting or transporting steel plates and construction elements. With high efficiency and easy maintenance, lifting clamps are convenient to operate and carry. They can be divided into horizontal lifting clamps, vertical lifting clamps, overturned lifting clamps and other types, which greatly reduce the resource of manpower and improve efficiency.  The unique design makes it possible that the heavier the load is, the tighter they grip it.

           Lifting clamps have the uniform distribution and they lift the heavy weight by opening the clamp jaw and gripping steadily on the goods. Operators should make the heavy goods reach the ground firstly and then take down the lift clamp in the case of zero loading. Two pieces of clamps are used for the testing, but 2 pieces or 4 pieces are recommended for lifting operation. Lifting clamps offer the users best performance and ensure perfect security under different work conditions. Besides, clamps can be used in single pairs, double pairs or tripod  configuration with a lifting sling.

           Lifting clamps can hold the plates with a friction gripping force, which can be locked through a lever, while holding the plate and till the lever is unlocked, the plates are not released. They usually consist of a body, cam, and cam pin and other parts. All of the major components are within the body made of die-forging for maximum strength and durability also there is no projection from the body for easy operation. The work piece cannot be lifted while the clamp is unlocked, and it will be possible to visually confirm that the clamp is unlocked. What’s more, the clamping force increases in proportion to the weight of the load. One thing that needs to mention is that single clamps can be used to transfer lightweight loads, but they are generally used in pairs when lifting and transferring heavier loads.

           They are widely applied to lift, move and turnover vertically or horizontally those goods that are often heavy and expensive such as steel plates, concrete  pipes, pulley blocks, metal sheets, posts and vessels in shipyards/shipping building fields, offshores, aircraft construction, woodworking, metal processing industries, subway sites, civil engineering construction sites, metal production workshops and other working fields. Those lifting clamps provide heavy duty beam clamps and girder clamps for harsh industrial environments including oil and gas, marine, steel mill general fabrication construction and maintenance.

           They are also called horizontal plate lifting clamps, vertical plate lifting clamps, vertical pipe lifting clamps, scissor grab lifting clamps, sheet metal lifting clamps, stone lifting clamps, vertical plate clamps, vertical lifting clamps, beam clamps with shackle, horizontal plate clamp, lever steel clamps, screw lifting clamps, pallet clamps, plate horizontal lifting clamps, lifting beam clamps, round steel pipe lifting clamps, high girder clamps, steel universal beam lifting clamps, good quality beam/tackle clamps, stainless steel beam clamps,  heavy duty/ swivel jaw beam clamps, crane vertical lifting clamps, hoist clamps for steel plate, bulb bar clamps, hanging steel plate lifting clamps and wide  jaw universal clamps, concrete grab, boulder grab, block grab, lifting tongs.

Detailed Description

1. Griplifting shackle
         There are safe and secure grips on the beam which are long life use. Serrated gripping cam bites into load or positive grip and clamps in position on edge of plate until tension is applied to the load sling.

2. Spring
         The spring attached to the cam assembly allows the clamp to close on any desired  spot and only one operator to place the clamps and guide the hoist. When they are under loading, operators have to up the lock lever to tighten lock spring. And when you could unload, make down the lock lever to loose lock spring. The spring-load tightening lock mechanism/ spring automatic close device assures a positive initial clamping force.

3. Safety mechanism
           Thanks to the safety mechanism, lifting clamps won’t slip under the circumstances that the load is being lowered or the lifting force is applied. There are also  equipped with optional locking device to control the work in case of emergency.
4. Jaw
         Those flattened or reinforced jaws that hardened for durability contact with high  surface, distribute load evenly and the light weight clamps with large and flexible jaw opening wide range of which rated load capacity and size of jaw opening are clearly shown on lifting clamps so that they can handle with different weight of loads. Besides, the screw jaw of the body can be changed with a button. Due to their variable jaw width, pallet clamps can grab pallets securely and automatically releases. Lifting clamps lift the heavy weight by opening the clamp jaw and gripping steadily on the goods and large jaw aperture enabling sheets of varying thickness to be lifted. Special clamp jaw design  applies load away from the flange edge, thus reducing stress of flange  which make them adjustable to fit a wide range of flange widths and beams.

5. Pads
           Along with jaws, pads are manufactured from high tensile steel and have heat treated serrated teeth.
6. Cams
         High-frequency quenching of special alloy steel cams  which are drop forged and heat treated for long lasting life and safe gripping power are suitable for plates of different hardness. They are preloaded cams with dual design. When the stopper mechanism is set, the cam with introduction hardened will be  locked in an open position, and will be easy to set the clamp onto the work  piece. Cam operations function as a lifting shackle ensuring a tight grip on the load which means the load is held firmly while goods are being lifted.

Different types
           1. Beam clamps
           Beam clamps, as equipment’s to quick form hanger or connect point beam monorail, are versatile lifting clamps with articulated lifting shackles for lifting and  transporting steel plates and structures from all positions such as horizontal, vertical and sidelong. Beam clamps made of stainless steel and equipped with a zinc-plated spindle are able to fit wide flange beams and available in various  styles which greatly reduce the resource of human labor. Beam clamps are manufactured with a forged steel attachment eye and there are versatile jaws designed to mount on a wide range of tapered or flat beams. They provide  a temporary or permanent mount to a wide range of tapered or flat beams. They are usually installed on the bottom flange of the beam, which adopt left and right screw thread construction for leading screw. Beam clamps should be formed a complete set with chain hoist or other lifting machines. Main parts of support strength are made by alloy steel and the scopes of adjustments are wide and convenient with thread handle. Due to in-built anchorage point, they adopt low headroom design. their function as semi-permanent lifting point for electric hoisting equipment, pulley blocks or loads.

2. Horizontal lifting clamps
           Horizontal lifting clamps are especially suitable for lifting, transporting and moving steel plates, templates, concrete pipes, box materials, parts or goods, profiled bar and construction in horizontal position, which are high efficient auxiliary machines. Due to the thickness of the steel plates, they are safer to use. Horizontal lifting clamps adopt “G” structure and forged head a d forged gear  set to ensure the durability and safety. One thing that needs to pay attention  is that they must always be used in pairs or multiples and avoid snatch or shock loading during the operation The horizontal lifting clamps are fastened to suitable slings and attached at three or more points on the load. The clamp is locked in closed as well as in open position. With long loads, we recommend using a spreader beam. The base is slotted to allow the clamps to be used from end of beams as well as from the flange. Besides, thanks to the tooth plate made of special alloy steel after high temperature quenching, they greatly enhance the strength and durability

3. Vertical lifting clamps
           Vertical lifting clamps with articulated eyes are usually suitable for vertical lifting of steel plates and steel structures. One piece of clamp is used for the  testing, and one piece or two pieces are recommended for lifting operation. One thing that needs to pay attention is that only lift one piece of the clamp one time and multi plates can be lifted. The main body and the shackle of vertical  lifting clamps are made of high-frequency quenching of die-forged special alloy steel which are optimally tempered for maximum strength and durability. They are fitted with a locking device for both open and closed positions, which ensures complete safety. It is necessary to pull upward  the shaft for straining the spring when hoisting the cargos. And press the shaft down when loading off, after releasing the spring, clamp and steel plate  will be separated from each other. Vertical lifting clamps adopt automatic powerful clamping mechanism that clamps securely in portion to the weight of the load. What’s more the force of clamps is more than twice of the lifting  load so that the material can be free from unnecessary scars.
           When  it comes to tightening, the clamp will lock  onto the work piece when the lock handle is pulled completely upwards. After  locked, the shock from the work piece coming to rest on the floor or the slackening of the sling rope will not cause the clamp to come lose from the work piece. What’s more, through pulling the lock handle, the clamp can be unlocked. And when unlocked there will be no clamping force on the work piece. Operators need to remember to never attempt to lift when the clamp is unlocked because clamping force on the work piece will be insufficient. The locking handle must be pulled up to tighten the spring and the locking handle is pulled down when unloading, the clamp and the plate can only be separated when the spring is loosened.
           Feature

  1. Full 180º  turning range for material transfer, turning or moving

  2. Quick and versatile rigging point for hoisting equipment

  3. Longevity and guaranteed safe performance with fixed lifting eye clamp

4. Round lifting clampsrolling lifting clampspallet clamps
           Pallet clamps usually made of metal are used for lifting the level of steel ingots and pulling loaded pallets, heavy crates with simple and reasonable structure but safe and reliable shipment flexible action. They are extremely easy and simple to use and make for safe lifting and available with spring an automatic close device to make sure the safety and maintenance when they are not used. Pallet clamps are usually picked with forklift truck. Besides, they are equipped with vice-controlled hook with crane shut up action switch. However, one thing that needs to mention is that pallet clamps can only hang by single drum and avoid overload use. When using, operators should to lock the screw counter-clockwise to clamps tightly and loosen the clamp mouse.
           A. Round steel vertical pipe lifting clamp
           This type of pallet clamps are designed to pick up similar round stock material, tubes, pipes and rolls with a diameter of a wide range. With automatic open and close device, they are extremely easy and simple to use and operate safely. The surface treatments of round steel vertical pipe lifting clamps are usually heat-treated and carbon steel teeth.

          B. Pallet puller clamp
           This type of pallet clamps picked with forklift truck are not designed for lifting but for pulling heavy crates and loaded pallets z-cross a smooth floor or loading trucks at ground level, which are heavy-duty and solid. Pallet puller clamps are equipped with toothed cam toe that ensures maximum grip/hold and standard jaw apertures allowing for wide range of plate thickness. There are variable jaw widths to make adjustments to grab pallets and clamps can securely and automatically release the work. Due to the scissor action, clamps can have superior grip and with lifting shackles, it is easy to replace wear parts.

Cautions
           1.  Select the lifting clamps which are used for their intended purpose and always ensure the operator has access to operating instructions.
           2.  Overload is forbidden strictly during operation so never exceed the working load limit to use and use it in the allowable load range and the range of plate thickness.
           3.  Only one round steel can be lifted at a time, accordingly, more than two pieces are not allowed.
           4.  When clamping lifting works processed, do not touch the lifting object or crash the hanging objects and cargo. And only those people who have the qualification can be able to precede the suspension and hanging work.
           4.  You must use horizontal clamps in pairs or more and avoid collision and suspended in the process of lifting
           5. Entering crane operating range or flip area and beating or impacting lifted good/clamps are strictly forbidden.
           6. During the lifting, you need to pay attention not to making the goods move or stop rapidly. Besides, don’t lift the weighted goods, it is best to use more  than two clamps to make sure being safe.
           7.  Before using, you have to check the mouth clamp the plate, gasket, the jams between tooth’s, wear state and other abnormal phenomena.
           8.  Lifting process cannot be hit by hanging objects and avoid snatch or shock loading.
           9.  Remember to read the product specification carefully before using it.
