La diferencia entre el polipasto de la cadena y el polvo de palanca

Qué es polipasto: Hand chain hoist is a simple to use, easy-to-carry manual lifting machinery ‘can be used in new factories, docks, open-air places without power supply for lifting heavy objects, hand-pulled hoists can also be used with running trolleys, walking on I-beam and other tracks.

Qué es lever hoist:The hand lever hoist is a simple to use, portable manual lifting tool.It is a manual pull handle that obtains a linear traction force that matches the load by means of the lever principle, and rotates on a pliers body of the load inside the movement to drive the load.

Similarity:  Both the chain block and Pulpa de la grúa are used to save effort by moving pulleys.

Diferente

Uno: el bloque de palanca de manos y las mismas especificaciones de elevación de la comparación del volumen de polipasto de la cadena de manos, el polipasco es mucho más pequeño que el polipasco de la cadena, y su función es más eficiente y el rango de aplicación es más amplio.

Dos: el accionamiento del bloque de cadena es una cadena de mano - extraída, la cadena de manos impulsa la rotación del piñón activo, el piñón impulsa la rotación de engranaje grande, la salida de torque amplificada, levantando así el peso, que se usa principalmente para levantar elementos verticalmente

Tres: el manuales palanca hoist is much smaller than the same lifting specification hand chain hoist, and its application is more extensive. Now the hand crane chain hoist can be used for factory, mining, agriculture, electricity, building production and construction, docks, docks, warehouses for mechanical installation, cargo lifting, vehicle loading and unloading, etc Especially suitable for open-air and power-free operations; ratchet lever hoist are widely used in industrial and mining, transportation, construction, electric power, shipbuilding and forestry and other departments of equipment installation, loose parts bundling, lifting goods, tightening lines and welding alignment and other occasions, especially in the absence of power supply and small places for traction more show its unique superiority.

Cuatro: la operación es diferente

Azulador de palanca:

   One:The cadena de grúa manual hoist will reliably fix the hook and fixture of the gourd, and the chain hook will be reliably hung together with the suspended heavy object.

Dos: levantamiento pesado de la palanca manual. Tire de la perilla hacia la "parte superior" de la placa de posición, luego tire de la manija al recíproco, y a medida que el mango se tira hacia adelante y hacia atrás, el peso aumenta suavemente.

Three: The decline of the weight of the hand wrench gourd. Place the knob to the “down” position on the sign, then pull the handle reciprocatingly, and the weight will fall smoothly as the handle is pulled.

Four:Adjustment of the position of the hook of the hand wrench. When unloaded, pull the knob to the “0″ on the indicator, and then turn the handwheel to adjust the upper and lower positions of the chain hook make the pawl that disengages the ratchet, so that the position of the chain hook can be adjusted conveniently and quickly by pulling the chain by hand.

Bloque de cadena:

As an upgraded version of the fixed pulley, the manual pulley chain block completely inherits the advantages of the fixed pulley, and at the same time adopts the combination of the reducer of the reverse reverse brake and the chain pulley group, and the symmetrical arrangement of the secondary spur gear rotation structure is simple, durable and efficient.The hand pull hoist rotates by pulling the manual chain and the bracelet wheel to press the friction blade ratchet and the brake seat into one and rotate together, and the tooth long shaft rotates the blade gear, the tooth short shaft and the spline hole gear.In this way, the lifting sprocket mounted on the spline hole gear drives the lifting chain, thereby smoothly lifting the weight. The ratchet friction plate type unidirectional brake is adopted, which can brake on its own under load, and the pawl engages with the ratchet under the action of the spring, and the brake works safely.
