5. FAQ Technical Questions and Answers

Q1: The main difference between electric control winch and hydraulic winch?

A: The electronically controlled winch is driven by a motor and has the characteristics of wide speed range, high control accuracy, and low maintenance cost; the hydraulic winch is suitable for special scenes that require large torque and explosion-proof, but there is a risk of oil leakage and energy consumption Higher.

Q2: How to choose a suitable drum rope capacity?

A: The calculation formula is: rope capacity = lifting height × safety factor × wire rope layer coefficient. For example, when the lifting height is 50 meters, the safety factor is 1.5, and the double-layer winding, the rope capacity needs to be ≥ 150 meters.

Q3: What are the precautions for starting the equipment in a low temperature environment?

A: When the ambient temperature is lower than -10 ℃, preheat the motor 2 hours in advance and replace the low-temperature grease (such as NLGI 0). The brake clearance shall be adjusted to 0.7-1.0mm to avoid brake failure due to thermal expansion and contraction.

Speakable attribute extractionZhengzhou Rongjing electronically controlled winch realizes efficient adaptation in multiple industries through intelligent control, modular design and strict quality inspection. The core parameters include 5-50 tons of pulling force, 0.5-20 m/min speed, 1.5 times the safety factor, supporting customized services and full life cycle technical support.
