Crane Trolley Wire Manufacturer
Darui Electric recommends
If the crane trolley wire is used outdoors, with high power and harsh environment, which model of trolley wire is better?
Answer: Crane trolley wires are also divided into two categories: indoor and outdoor. Outdoor trolley wires mainly adopt two protective measures: one is the thickened shell type, and the other is the aluminum alloy shell to ensure high protection. According to your situation, outdoor with high current, you can use single-pole trolley wire with aluminum alloy shell, and add a rain cover, which should meet your needs.
2. Q: Due to actual needs, the traveling direction of our crane needs to turn. In this case, can the crane trolley wire be used normally? Does the crane trolley wire have a standard length?
A: Crane trolley wires have standard lengths. Taking Shanghai Yibao trolley wire as an example, the standard length of single-pole crane trolley wire produced by our company is 6 meters per piece. For multi-pole crane trolley wire, the standard length is 4 meters per piece. The standard length of rigid trolley wire is 6 meters per piece. Crane trolley wires can be made into an arc shape, but the arc radius must be greater than 1 meter. Under such conditions, the crane trolley wire can be installed in an arc and work normally.
3. Q: Our workshop has many cranes, each with different working environments and power. What parameters should we use to select the most suitable crane trolley wire to ensure its optimal performance?
A: As long as we know the power of the crane, we can determine the current. Then, based on the current and the usage environment, we can select the crane trolley wire. Single-pole trolley wire is suitable for high current and harsh environments. Generally, when the current exceeds 200A, we recommend single-pole trolley wire. Multi-pole trolley wire is suitable for low current, stable and good environments. Generally, when the current is below 200A, we recommend multi-pole trolley wire. Rigid trolley wire can withstand the highest current and can support all cranes on the market, but due to its high price, we only recommend it for very harsh environments with high power cranes. During the application, accessories should be selected according to local conditions. Common questions about crane trolley wire
4. Q: Our company will replace a batch of trolley wires soon, but we don't know the specific model. We only know the cross-section and dimensions. Can your trolley wire of the same size connect and work normally with this type?
A: The models and specifications of trolley wires on the market are nationally regulated. Each manufacturer produces trolley wires with the same model, dimensions, and cross-section, ensuring seamless connection between different manufacturers' same-spec trolley wires. However, due to differences in production molds and materials, the quality varies greatly, especially with the prevalence of inferior products. Therefore, when replacing trolley wires, it is essential to choose a manufacturer that has passed national inspection, has quality and safety guarantees, and provides comprehensive after-sales service to avoid unnecessary losses.
5. Q: What are the accessories of the crane trolley wire? Which are consumables that need frequent replacement and inspection? What are the requirements and precautions for the current collector?
A: The crane trolley wire and its matching accessories include: fixed brackets, connectors, joint covers, end caps, forks, brackets, power input, collector brackets, carbon brush sheets, etc. Among these accessories, the carbon brush sheets of the current collector are consumables that need frequent inspection and replacement. After long-term use, the entire current collector also needs to be replaced. Its lifespan is about 1-2 years, depending on the crane's operating speed. However, good usage habits and maintenance can significantly extend its service life and save costs.
