JKL Manual Free-Fall Fast Hoist Winch for Construction
Winch Introduction
The JKL free-fall winch (manually controlled rapid free-fall type) is available in models JKL2, JKL3, JKL5, JKL6, JKL8, and JKL10, with rated pulling forces ranging from 20 to 100 kN. It is designed for vertical lifting of heavy loads in construction sites, factories and mines, ports, and other engineering applications. It is particularly well-suited for free-fall impact piling operations in bridge pile foundations, dock piling, and building foundation works — the JKL5 model is commonly used for pile foundation construction within 30 meters, while the JKL8/JKL10 models are ideal for deep excavations and large-tonnage impact piling. Its key structural feature is the rotating main shaft (commonly referred to as the rotating shaft), ensuring flexible and reliable operation.

FAQ
Q: What national standards do JKL free-fall hoist winches comply with?
A: Design & manufacturing follows GB/T 1955 (Building Hoists) standard; safety performance meets JB/T 9008 (Wire Rope Electric Hoists — Safety Regulations); installation acceptance is carried out per TSG Q7014 (Supervision and Inspection Rules for Installation, Retrofit and Major Overhaul of Lifting Appliances).
Q: What's the difference between JKL free-fall hoist winches and standard JK hoist winches?
A: The JKL is a manual free-fall type — the clutch control enables gravity-assisted pile punching and piling, making it ideal for bridge foundation work. The JK is an electric quick-lift type designed for routine vertical lifting. They serve different job site applications and are not interchangeable.
Q: What's the price range for each JKL free-fall hoist winch model?
A: JKL2~JKL3: RMB 3,000~8,000; JKL5~JKL6: RMB 12,000~25,000; JKL8~JKL10: RMB 28,000~50,000. Non-standard customizations are quoted separately. Prices are subject to tax and freight confirmation.
