When we choose a jib crane, we need to make good purchases, and there are many types of purchases, which can be purchased in a variety of ways. So, what is the purpose of its contact wire? Let's give you a detailed answer.
How to choose a jib crane:
1. According to the structural difference: column cantilever crane, wall cantilever crane, mobile cantilever crane.
Column type jib crane refers to a cantilever crane in which the cantilever equipment is on the column, the cantilever structure rotates on the column, and the walking lifting equipment moves back and forth to lift heavy objects.
2. The wall-mounted jib crane refers to the main equipment on the wall and rotated through the cantilever arm.
The jib crane for lifting heavy objects mobile jib crane refers to the whole structure of the jib crane can be moved, divided into two kinds of hand push and electric, the other structure remains unchanged, this is mainly in the small tonnage is more, the common one is 150kg-1T.
3. According to the driving method of rotation, it is divided into electric rotary jib crane and manual rotary jib crane.
Electric rotary jib crane refers to the rotation of the cantilever through the electric motor and reducer to complete the rotation of the cantilever jib, the advantage is to save labor, easy to operate, but at the same time the cost is higher.
4. Generally used for medium and large tonnage cantilever cranes of 1t and above, manual rotating jib crane refers to the rotation of the cantilever by hand or hand pushing, etc., relying on the external force of the human body to rotate the jib crane. This kind of cost is low, the structure is simple, the overall price is low, and it is generally used for jib cranes of 1t and below.
The function of the jib crane contact line:
1. The sliding contact line collector is one of the important components of the power supply such as suspension cranes and suspension cranes. How to choose the right slip line collector is very important.
2. The conductor is mainly a shoe box, shoe plate, spring bracket, and part of the collector support. First, we can divide the heat collector of the current conductor line into heavy and light collectors, which is based on the current conductor line to determine that the general conductor line current is equal to or less than 500A, and the light collector can be selected.
3. In the selection of the trolley line, we must consider that the manufacturer matches the trolley line, do not choose the collector, otherwise, it will affect the normal operation of the driving area of the suspension crane and cause greater damage to the sliding line. The collector is brushed with high copper-carbon based pressure. After purchasing, it is necessary to see if the type of contact wire is in line with the type, since the collector itself is consumable, it will wear the brush for a long time, so the degree of the brush on the collector should be checked regularly and replaced regularly.
