Electric hoists represent their own machinery, strength, and toughness, while the stage is elegant, flowing, and soft, with conflicts and collisions between the two.

What factors cause such light hand pull?

The hand chain hoist saves effort by pulling the galvanized hand chain pulley by hand, and then according to the working principle of the pulley of the chain hoist. The lighter the hand pulling force when lifting the same heavy object, the better the transmission performance optimization of the hoist. And what can affect the strength of the hand is to improve the design and optimization of the gourd parts.

1. Reduce friction: The lower the friction of internal gear components, the better the transmission conversion effect, and a light hand pull can also pull more weight. For example, the combination of a lifting sprocket with needle roller bearings and a long shaft reduces friction.

2.The overall bearings carried by the left and right wall panels and outer wall panels also play a role in optimizing the transmission mentioned above.

3.In addition to reducing friction, speed ratio is a key factor in achieving labor-saving. The larger the speed ratio, the better the lifting force, and the more teeth there are in the disc gear assembly and spline gear.

4. At the same time, the light pulling force cannot be separated from the accurate engagement of the sprocket and chain, and a reasonable friction force is needed to drive the entire manual hoist to rotate.

The above are several factors that affect the pulling force of manual lifting hoists, which can be considered as directions for selection.
