The so-called 4 ton hand cable puller, also often referred to as a ratchet retractor, is generally used in overhead line installations as a tensioning wire. When using, you need to loosen the wire rope or galvanized iron wire on the 4 ton hand cable puller and fix it on the crossarm. Then use the clamp to clamp the wire and then pull the special wrench.
With continued use, for the 4 ton hand cable puller, due to the reversal effect of the pawl, the wire rope or galvanized iron wire will be slowly wound on the ratchet drum to tighten the wire. Secure the tightened wire to the insulator. Then loosen the pawl to loosen the wire rope or galvanized iron wire, loosen the wire clamp, and finally wrap the wire rope or galvanized iron wire around the ratchet wheel.
From the current point of view, the 4 ton hand cable puller includes different types, so the user can flexibly choose according to his own needs when using it. Among them, hand-pulls (hands-pull) hoists are mainly used for pulling various types of cables such as wires for power and overhead lines, and heavy objects such as towing and transporting equipment, as well as fixing large-scale equipment and other goods during transportation. Hand-pulling (hand lever) hoist has two kinds of hand-pulling and hand pulling.
It should be noted that in order to ensure safety, when using 4 tons of manual tighteners, there are several issues that need attention: First, manual tighteners should be selected according to the thickness of the wire. When using, the wire rope should be straightened and must not be distorted. Secondly, the ratchet wheel and the pawl should be in good condition. There should be no tripping phenomenon. In practical applications, it is necessary to add proper amount of oil lubrication.
In addition to the above requirements, when we use a 4 ton hand cable puller, if we find a slippery line, we should immediately stop using it. We must take corresponding measures, such as winding a wire on the wire, etc. The wire is securely clamped before it can be used again. At present, 4 tons of manual tightener is mainly used in construction, roads, bridges, metallurgy and other industrial fields.
