puller - hubzug

What is Mechanical Hubzug?

Mechanical (pulling) hubs are the modernized version of the pulley logic that has been used since ancient times. It consists of two fixed and one movable free wheels concentric and rotating together. They are widely used in businesses due to their easy maintenance and small size.

The biggest feature of Chain Pullers is to pull the target load and get it closer to the reference point. The advantage is that the force required for the movement of a heavy load is very low at hand strength levels. The disadvantage is the prolongation of the pulling time of the load, that is, the time is lost as the load wheel moves very little in one revolution of the handwheel.

What Should We Consider When Choosing Hubzug?

How to Choose the Product:

First of all, we need to calculate the capacity we need correctly. First of all, the mass weight of the target load determines our target load. Another choice is to determine the distance that the load should be pulled.

Security:

Our products are manufactured on the basis of a safety factor of 1x1.5 during the production phase. For example, 1500 kg of our 1000 kg capacity product is tested and offered for sale.

Another factor of our safety is the quality of the load chain used. Chain produced in grade 100 load chain class is used in our products. The Safety Coefficient is 5:1. For example, the chain of 1000 kg hoisting chain breaks at 5000 kg.

Another security factor is the strength of the hooks. The lower or upper hook is produced in the form of grade 80 and the safety factor is 4:1.

The safety latches at the ends of the hooks prevent them from coming off the hook. The upper and lower hooks with swivel prevent the hoist from twisting and jamming.
