Frequently Asked Questions
Q1: How does the Extreme Cold Version perform in ultra-low temperatures?
The Extreme Cold Version is engineered with Q355D and Q355E steel for critical structural plates, maintaining exceptional toughness and ductility down to -40°C. Additionally, it incorporates cabinet heaters, low-temperature-resistant cables, and preheaters for the engine and hydraulic systems to ensure reliable performance in freezing climates.
Q2: What are the power options for the C8H crawler mobile screening plant?
The screening plant features a dual-power supply system supporting both diesel-electric hybrid drive and all-electric mains power. This allows the machine to run on a 100 kW generator set or plug directly into the local power grid to minimize fuel consumption and emissions.
Q3: What is the production capacity and screening area of the machine?
The overall machine offers a production capacity of up to 300 t/h. It features a three-deck vibrating screen with an extra-large screening area of 6000 × 2000 mm (parameters list 6000*1970 mm) to ensure high-capacity and precision screening.
Q4: How does the Intelligent Travel System handle complex terrains?
It utilizes a crawler chassis designed for complex terrains, allowing autonomous mobile operation without requiring a fixed foundation. The system is enhanced with load-sensing pumps and proportional valve groups for automatic deviation correction and stepless speed control.
Q5: What measures are taken to make maintenance easier for operators?
Maintenance is simplified through a hydraulically liftable feeding system and adjustable screen height, which provide ample space for screen replacement. It also features easily accessible power components, side-mounted motors with direct drive, and a touch panel displaying real-time system status for quick troubleshooting.
Q6: How durable is the feeding system under heavy loads?
The feeder is built using a highly robust dual-layer structure composed of Q355B and NM400 wear-resistant steel. It also features a hydraulically adjustable grizzly at the feed inlet to effectively screen out oversized feed material and protect the machine.
