Specialists in rail tracks and bridge cranes

In the industrial world, lifting solutions play a pivotal role in optimizing productivity and safety. Among the most common tools used for vertical lifting are electric hoists and manual chain hoists. Understanding the differences between these two is essential for choosing the right equipment for your operational needs. At Dorance, we are proud to offer expert solutions for lifting systems with a proven track record in demanding environments across Latin America. What Is a Polipasto Electrico? A Polipasto Electrico is a powered lifting device that uses electricity to lift or lower heavy loads. It typically features a motorized mechanism that offers efficient and fast lifting with minimal manual effort. These hoists are often part of crane systems and are especially effective in industrial environments where speed, consistency, and high load capacity are critical. What Is a Manual Chain Hoist? A manual chain hoist, by contrast, relies on human effort to lift a load via a chain pulley ...

Imagine yourself in an industrial complex in Colombia, where large construction steel columns are being transported with no problem. That is the beauty of the bridge cranes! They are used in lifting and shifting of loads, making work easier and less hazardous.  In this post, I will introduce you to the world of bridge cranes Colombia, focus on Dorance – the company with 59 years of experience, and describe its components. It is interesting for anyone who wants to learn about the types of industry tools or is an industrialist to learn why the bridge cranes can make a huge difference. What Are Bridge Cranes? Overhead cranes also referred to as bridge cranes are designed for lifting and lowering of loads as well as lateral transportation of loads across the building. They have a beam or a bridge and this structure is large and is supported by runways with a hoist that moves on this beam. Simple, right? These machines are ideal where loads are heavy as in the production sheds and the h...

Crane rail inspections are very important for ensuring that overhead cranes stay safe and functional over time. Wear and tear, natural, and sometimes improper installation cause a defect over time, which definitely deteriorates the performance. Therefore, in this blog, we have detailed the most common defects observed after rail inspections, their implications, and solutions to fix them. Here at Dorance, we are professional and dedicated to excellence in ensuring your crane rail systems will perform at an optimal level. Common Crane Rail Defects 1. Rail Misalignment Rail misalignment occurs because of wrong installation, thermal expansion, and heavy loads. The misaligned rails cause unequal wheel wear as well as enhance stress on the crane components with the possibility of an operational failure. Solution: We use advanced instruments like topographic surveys for accurate rail alignment. We correctly align the rail by adjusting, high-performance grout application, and rail clips' i...

Proper maintenance of rail clips and pads is critical to ensuring the smooth operation of overhead cranes. These components bear immense stress, playing a vital role in securing rails and reducing vibration. By following regular maintenance practices, you can enhance the longevity of your crane systems. Here are ten actionable tips to keep your clips and pads in top condition, and why Dorance is your trusted partner for crane runway solutions.   1. Regular Visual Inspections    Inspect your clips and pads frequently for signs of wear, corrosion, or misalignment. Early detection of damage prevents larger, more expensive issues. Pay special attention to areas with high stress or exposure to harsh conditions.   2. Ensure Proper Alignment    Misaligned clips can lead to uneven load distribution, causing premature wear on both the clips and pads. Regularly check and adjust the alignment to ensure a secure and balanced connection between the rail and it...
