3. The pulley of this product is a hot-rolled steel wheel made by advanced International technology. It has reasonable structure, high load, high bearing pressure and reduced friction with wire rope.

The new energy-wind power generation has been greatly carried out at home and abroad. Wind power is an environmental and clean energy.Meanwhile, the hoisting solution of wind power designed by the Dawson block research center has been successively applied in the installation works at home and abroad.

1. Reinforced plate and special sealing device:resistance to corrosion.Both sides of the middle shaft are installed with water-proofing sealing devices.

As there are requirements for the resistant to corrosion and impact force, Dawson Block Design Center has innovated and adopted reinforced plates and special sealing device. Thus, impact force has been greatly strengthened and hoisting and pulling and pushing safety is greatly improved. A,B,C,D and ZHC marine blocks are available. The solution for hoisting and underwater hauling is provided for dozens of shipbuilding enterprises, including Qingdao Ship Yard, Shanghai Ship Yard and Yantai Raffles and so on.

1. With the wire rope locating and anti-disengaging device, the wire rope will not fall from the groove and the guard plate and pulley will not be damaged.

Mining block is a special lifting tackle that is self-researched by our company for the coal mine industry, which has filled in the gap of Chinese tackle industry. As the operation environment of inside mine is severe and complex, horizontal drawing, non-linear pulling and pulling from different angles are required.Different from the traditional vertical hoisting, horizontal drawing or non-linear pulling is required for coal mine tackle. Therefore, Dawson Block Design Team has closely communicated with the clients by operation survey and has designed the mine tackle, which has filled in the industry gap.

Application:the product is used to place the wire on the straight line pole. The pliers-connected pipe, wire rope connector and rotary connector pass through the groove.

Application: applicable to assembling the pole and tower, wire stringing, hoisting equipment and other overweight operation during electric line construction.

Our technology research center has researched the key part of tackle”pulley” in order to solve the disadvantages of traditional cast iron and cast steel pulley. Through repeated test, large multi-pulley singing tackle with”single-plate” hot rolled steel sheave” has been successively produced. The tackle has been applied to large projects, such as the Three Gorges, Qingdao Port, Raffles drilling platform borehole.

Pulley blocks are also known as snatch blocks, these pulleys open so it’s easier to feed the rope through the housing—a free rope end is not needed. Use them to assist with horizontal pulling or to guide a rope.

Sheaves and pulley blocks are devices that aid the lifting or pulling of loads. They mount to a surface or suspend from equipment and have a grooved wheel (sheave) for guiding a wire rope or aircraft cable that"s attached to the load. Pulley sheaves are replacement wheels for pulley block assemblies.

They work by distributing the weight of an object over multiple points of contact through the use of friction. A block and tackle is an assembly of pulley blocks and rope or cables that are set up to decrease the effort needed to haul or hoist heavy loads. Each block has one or more pulley. Thread the rope, alternating between the pulley attached to the block on the object you want to move and the pulley attached to a fixed block.

A snatch block or snatch pulley is an assembly using a wheel with a grooved edge for holding a rope or cable. They typically have side plates for attaching to a hook or shackle, with an axle or pin for turning the sheave. It is sometimes called an open block pulley

Pulleys are generally smaller and lighter-duty than blocks. Most are designed for use with soft rope, although some are designed with steel sheaves for use with wire rope.

Used properly, It enhances the pulling power of your winch and changes the pulling direction without damage to the wire rope. Reeving blocks to set up a double pulley system requires a little thought. A double pulley system, also known as a "block and tackle," consists of the pulleys, or blocks, and the tackle, the ropes riven through the blocks.

Blocks can assist you in lowering by reducing the abrasion and friction on your bull rope thus making your ropes last longer. All blocks are rated by rope size and their average working load can be estimated by using is a 5:1 ratio. (Example: Block with 5,000 lb. rating would have a working load of 1,000 lbs., etc.)

Pulleys with two grooves are for use where multiple pulleys move a single load, such as block and tackle systems. They require about half the force of a single-groove pulley to move the same load. Warning: Never use to lift people or items over people.

They are widely used to lift heavy loads when only "manpower" is available and are sometimes used in conjunction with motorized lifting tackle. By using "fixed" and "movable" pulleys it is possible to gain a Mechanical Advantage. The capacity at which our products can be safely used has been established through an accredited testing laboratory. This may be defined as the safe working load limit, or cable rope pulley block load calculation, or a force calculator. The safe working load limit (mechanical advantage) is the maximum load in tons which should ever be applied, and when the load is applied uniformly and in direct tension to a straight segment of wire rope. By changing the degree of angle between lead and load angle, this also affects the stress on the block. The stress on the eye may be decreased by increasing the angle between the load and the lead angle.
