Popolna analiza strelnih žerjavov: podrobna razlaga strukture in varnega delovanja

The core principle of strižni žerjav is based on lever mechanics. Through the extension and rotation of the boom, combined with the lifting mechanism, the vertical lifting and horizontal displacement of heavy objects can be achieved with less power.

Stebričasti žerjav: It has a pillar fixed to the ground as a solid support for the entire crane. The boom can rotate 360 degrees around the pillar, and the motor, reducer and other power devices can accurately control the operation.

Žerjav na kolesih: The bottom is equipped with a moving wheel or track system to facilitate the movement of the whole machine. At the same time, there is a stable chassis to ensure the balance during movement. The boom structure is similar to the fixed column type but pays more attention to portability.

Stenski žerjav: The fixed frame is tightly installed on the wall, relying on the load-bearing capacity of the wall to share the pressure of the heavy object. The cantilever design is compact and does not occupy ground space.

Zgibni žerjav: The unique folding arm can flexibly change the extension shape, and the joints use special connections and drives to adapt to complex working spaces.

Different types have their own advantages. Pillar jib crane has precise positioning, suitable for fixed-point and high-frequency lifting, and reduces repeated positioning time. Jib crane on wheels can quickly reach multiple work sites, saving time for material lifting. Although the wall mounted jib crane is limited in movement, it can efficiently use vertical space in a small space and has a short lifting process. With its flexible arm span, the articulated jib crane can quickly grab the target heavy objects in irregular stacking areas and reduce the time for adjusting the angle.

Safety Operation Guide

-Before operation, be sure to check the connection and lubrication of each component to ensure smooth extension of the boom and reliable braking.

-During lifting, strictly operate according to the rated lifting capacity, overweight is strictly prohibited, heavy objects must be firmly tied, and the center of gravity is adjusted to the bottom of the boom.

-During operation, the operator should concentrate and pay attention to the abnormal sound, vibration and other abnormalities of the strižni žerjav at any time, and stop the machine immediately in case of emergencies.

-Regularly lubricate mechanical parts, such as boom joints and rollers, to extend the service life. Check the insulation and aging of the electrical system and prevent leakage short circuit. Perform flaw detection on structural parts such as booms and columns to detect fine cracks in time and ensure structural strength.
