The use of various types of sliding wires on electric single beam cranes

For an electric single beam crane, its operation relies on the application of any component. Take the sliding wire as an example. Without its current transmission, it is difficult for the equipment to operate. Due to the different types of contact and sliding wires used in different occasions, today the Shandong single beam crane manufacturer will introduce the use of various types of contact and sliding wires.

1、 Single touch sliding line

The single Ji energy-saving combination sliding wire is currently a widely used sliding wire for bridge cranes in the market. The conductor material is conductive aluminum or copper, among which aluminum sliding contact wire has a high market share. Its product has good conductivity, high cost-effectiveness, reliability, and a modular design that is easy to install and maintain. It has a wide range of applications and can be used in various indoor and outdoor environments. The current range is available from 200A-2000A, which can meet the product requirements of different devices.

2、 Tube type multi touch sliding line

The tube type sliding wire embeds the conductor in the PVC shell, which is easy and simple to install. It uses purple copper as the sliding conductor of the bridge crane, with good conductivity. However, due to the limitation of the inner groove of the shell, it is more suitable for low-power mobile equipment.

3、 High temperature rigid body contact slip line

The high-temperature rigid body crane contact sliding wire is composed of copper conductors and steel structural skeleton or aluminum profiles. It has high mechanical strength and good rigidity, and can withstand strong impact currents. Copper is used as the conductor, which can carry currents of over 3000A. The rigid body bridge crane contact sliding wire has no shell as protection, a large heat dissipation area, low temperature rise, and long service life. Due to the special material, it can be applied in high temperature, high pressure, high humidity, strong corrosion, and high dust environments, such as steelmaking, metallurgy, chemical industry, ports and other industries.

How to check and maintain the damaged electric hoist of a bridge crane

Bridge crane is a common crane in the current market, with a large and frequent usage, which leads to weak durability of bridge crane accessories. Therefore, Shandong bridge crane manufacturers will explain how to inspect and maintain the damaged electric hoist of bridge cranes.

1. It is necessary to carefully check the main control circuit and cut off the power supply of the hoist motor; Prevent the main and control circuits from suddenly supplying power to the three-phase motor and causing it to burn out, or prevent the hoist motor from coming into operation and causing significant harm.

2. Next, pause and jog the switch to start, carefully inspect and analyze the control appliances and circuit conditions inside. Repair and replace electrical appliances or circuits. Until it is ensured that there are no faults in the main and control circuits; Only then can it be started.

3. When the voltage at the motor end of the hoist is found to be lower than 10% compared to the rated voltage, the goods cannot be started and operated normally. At this point, it is necessary to use a multimeter to measure the pressure.

The damage caused by diagonal pulling is a human operation problem. It is not a quality issue with electric hoists. Currently, it is unknown how many accessories need to be replaced. Due to the large number of replacement parts, the equipment was not fully repaired on site, and the accessories were also incomplete. The expenses for maintenance personnel on business trips are also relatively high. Taking all factors into consideration, the manufacturer suggests returning the electric hoist for repair. The user shall bear the round-trip shipping cost, accessory cost, maintenance cost, packaging cost, etc. for the electric hoist to be returned to the factory for repair. This is a fast, cost-effective, and convenient method.
