Special Features: High-Speed & Heavy-Duty Class Operations
Hoists operated under arduous conditions—heavy lifts, high-intensity operations, frequent motor starts, high speeds or greater lift heights—need special features to withstand usage in these applications over their lifetime. In addition, some industrial processes have complex and unusual handling requirements and specific safety needs beyond standard features.
These high-speed and heavy-duty class operations are integral to maintaining a competitive advantage and ensuring smooth, efficient and cost-effective production in a variety of industries, such as:
- Automotive
- Warehousing & Logistics
- Steel & Metal Processing
- Precast Concrete
High-Speed & Heavy-Duty Class Operations
Quick Load / Unload Features
Inverter hoisting controls provide an extended speed range, enhancing load handling when the load is on the hook and increasing speeds when the hook is empty, thus decreasing cycle times while improving operator precision. The ability to select infinitely variable speeds within the rated speed range can maximize load handling efficiency and safety.
Industries and examples:
Automotive: Fast and efficient handling of vehicle components and parts.
Warehousing & Logistics: Quick loading and unloading of goods to expedite shipping and receiving processes.
Steel & Metal Processing: Rapid movement of products for efficient processing and distribution.
Robust Construction
The PDW heavy duty wire rope hoist delivers excellent performance in process duty applications for Class D and Class E duty cycles. It is designed for loads ranging from 6 to 80 tons (6,300 to 80,000 kg) and is available with a wide range of hoist speeds and lifts. The hoist also comes standard with control features, such as inverter hoisting with load float and an extended speed range, which are crucial for high duty cycle applications.
Industries and examples:
Steel & Metal Processing: Moving and processing large metal slabs and coils under demanding conditions.
Precast Concrete: Lifting and positioning heavy concrete elements during production and installation.
Protecting Your Investment
Selecting an appropriate duty cycle rating for your hoist is the most crucial step in protecting your investment and ensuring hoist longevity. Features like Class H motor insulation boost the heating capacity of the motor by increasing the maximum permissible temperature rise, which makes the motor more rugged for high-temperature or heavy-duty use applications.
Industries and examples:
Steel & Metal Processing: Ensuring reliable operation in high-temperature and heavy usage environments typical of steel production.
Precast Concrete: Operating in heavy-duty conditions with substantial thermal loads during concrete curing processes.
Condition Monitoring
HoistMonitor® Enclave is added to all R&M wire rope hoists for overload protection, hoist duty cycle monitoring, shock load prevention, fault and service warnings and predictive maintenance capabilities.
Industries and examples:
Automotive: Monitoring hoist usage to predict service needs to be planned during scheduled shutdown events.
Warehousing and Logistics: Ensuring safe and efficient handling of varied loads and improving overall safety.
Steel & Metal Processing: Protecting against shock loads and ensuring the longevity of hoisting equipment under heavy use.
Precast Concrete: Monitoring the condition of hoists to maintain safe operations and prolong equipment life in harsh environments.
Critical Benefits of R&M’s Special Features for High-Speed & Heavy-Duty Class Operations
High-speed and heavy-duty class operations are vital for several critical aspects of these industries, ensuring they can operate efficiently and effectively for the full expected lifespan of the equipment. Here are the primary reasons these special features are crucial:
Increasing Productivity and Efficiency
High-speed operations need features that can handle large volumes of products or materials, allowing industries to produce more quickly without sacrificing safety and equipment durability. These features allow for the swift production of goods, reducing the time needed to complete tasks and increasing overall throughput.
Reducing Costs
Automated high-speed operation features can decrease the need for manual labor, which reduces labor costs. Equipment designed specifically for the correct duty cycle of the application has a more predictable and less frequent maintenance schedule and longer lifespan. Investing in these features on the front end makes operations more efficient, lowering the cost of production and the need for unscheduled maintenance.
Scalability and Flexibility
High-speed and heavy-duty applications allow businesses to adapt to demand by quickly scaling production to meet increasing market demands or project requirements. With special features, these versatile applications can be adapted to several different tasks, making it easier to switch between different types of production runs without significant downtime.
High-speed and heavy-duty class operations are vital for maximizing productivity, efficiency and quality while minimizing costs and downtime. They enable industries to scale operations, meet deadlines, ensure safety and adopt sustainable processes, all essential for maintaining a competitive edge in today's fast-paced market. Selecting the right features and hoist duty cycle ultimately saves money as the crane lasts longer, repairs are less frequent and the potential for downtime is greatly minimized.
