Spiral jack lifting height

Spiral jacks can easily and quickly support and lift heavy objects, but there are also requirements for the lifting height of the jack. The lifting height of the jack sleeve cannot exceed the red warning line.

1. When lifting the jack, attention should be paid to the lifting height of the lifting sleeve. If the lifting height of the lifting sleeve is too high, running the jack will cause it to spin and damage the gears of the jack.

2. When the main shaft shows a red warning line during the lifting of the jack, the lifting operation should be stopped immediately to prevent the jack from lifting beyond the rated height and causing damage to the jack.

When using a screw jack, it should be operated according to the required specifications to ensure the safe use of the tool.
