El grúa giratoria en venta is a light and small lifting equipment. As a kind of mechanical equipment, its operation is very risky, so it is very important to do protective work. Today we first introduce the safe operating procedures of jib cranes.
The equipment personnel of the jib crane must hold the relevant certificates for replacement parts before operating. It is necessary to wear a safety helmet, suitable clothes and safety belt when working. Professional lifting equipment is required during hoisting, and an appropriate crane must be selected based on the load of the cantilever crane itself. According to the “Safe Operating Procedures for Cantilever Cranes”, operators must work under the suspended objects to prevent them from falling and endangering personal safety. The wire ropes used for jib cranes must not be broken, twisted or broken. The wire rope must be selected according to its weight to ensure its normal and safe use. Cantilever crane equipment is equipped with safety protection facilities. Please fasten your seat belt before using the industrial jib crane for sale. Ladders should be free of cracks and damage. Ladders must be securely attached before use. When the ladder is not high enough, it is prohibited to place other items under the ladder.
A top manufacturer jib crane for sale is a light-duty operation-strength crane composed of a column, a reversing arm, a reversing drive device and an electric hoist. It has the advantages of light weight, large span, large lifting capacity, economy and durability. It has high mechanical efficiency, convenient equipment, operation and maintenance, and low cost. The cantilever column is made of round tubes, the bottom plate and the rotating shaft are welded at both ends, and the upper part is equipped with a waist ring track. The base plate and the concrete base plate are connected and fixed with chemical bolts to ensure the stability of the cantilever crane. There is a through hole on the rotating shaft to complete the concealed installation of cables from the column. A 360° current collector can be installed on the rotating axis to realize n×360° rotation of the rotating arm. The jib crane adopts circular trajectory rotation. There are multiple through holes on the track for equipment limit stops, which can complete angle constraints from 0 to 360 degrees. The structure of the jib crane is composed of I-beam and I-beam steel, which can be used in various chain crane equipment and operations.
Both ends of the jib crane are equipped with movable pulleys to ensure that the crane operates within a specific stroke. The bracket of the jib crane is made of rectangular tubes and steel plates welded to support the rotating arm. Triangular support, superior mechanical structure, light weight and high safety. Two swivel wheels are installed under the bracket. The wheel tread cooperates with the waistband track, and the structure is stable. One is the driving wheel, which is driven by a light worm gear reduction motor to realize the electric rotation of the jib crane. The cantilever crane reversing equipment uses a round tube as the casing, and is equipped with an aligning roller bearing inside to realize the free rotation of the arm. Due to the performance of spherical roller bearings, jib cranes can be used safely even if the concentricity of the waist ring and column are slightly different. A C-shaped track can be installed on the swing arm of the top factory jib crane for sale, which is used to install the power cable of the electric hoist.
