Ventajas
En JTP, 2JTP, JTPB, and 2JTPB series mine hoists are robust and high-performance drum-type hoisting systems designed for vertical and inclined shaft applications in mining operations. These hoists are widely used for lifting coal, ore, personnel, and mining equipment en coal mines, metal mines, and non-metallic mines.
- JTP: Single-drum hoist for medium-duty lifting operations.
- 2JTP: Double-drum hoist for deep-shaft mining with balanced load distribution.
- JTPB: Single-drum explosion-proof design, suitable for mining environments with risks of gas or dust explosions.
- 2JTPB: Double-drum explosion-proof design, combining deep-well hoisting capabilities with explosion-proof safety, intended for complex operating conditions requiring high safety standards.
Compliant with safety and performance standards, these hoists ensure efficient, reliable, and safe transport of materials and personnel in mining environments.
Key Features
- High Torque & Variable Speed Control– Equipped with variable-frequency drive (VFD) motors for smooth acceleration/deceleration.
- Advanced Braking System– Disc or shoe brakes with fail-safe mechanisms (automatic braking in power loss or emergency).
- Intelligent Control– PLC-based automation con closed-loop speed regulation, fault diagnostics, and real-time monitoring.
- Modular & Durable Structure– Two-stage helical gear reducer, elastic couplings, and drum gear transmission for high efficiency and longevity.
- Multiple Safety Protections– Overspeed, overload, slack rope, depth limit, and emergency stop functions for compliance with mining safety regulations.
Typical Applications
- Vertical/Horizontal Transport– Coal, ore, waste rock, and mining materials.
- Mine Shafts & Inclined Tunnels– Suitable for deep-shaft mining operations.
- Personnel & Equipment Hoisting– Safe and controlled movement of workers and machinery.
These hoists are designed for heavy-duty performance y minimal downtime, making them ideal for modern mining operations.
Nota: In the JTP model, “J” represents winch, “T” represents hoisting, and “P” represents disc brake.
Estructura del producto
【JTP(B)/2JTP(B) Structure】
The JTP serial hoisting winch consists of the following key components:
- Drum Assembly - Responsible for winding and releasing the steel wire rope; available in single or double configurations.
- Braking System - Includes disc brakes or shoe brakes for controlled stopping and emergency halts.
- Reduction Gearbox - Transmits motor power efficiently while reducing speed to optimize torque.
- Motor principal - Typically an AC or DC motor (160–1600 kW) driving the drum via the gearbox.
- Sistema de control - PLC-based or relay-controlled for smooth acceleration, deceleration, and safety interlocks.
- Foundation Frame - Provides structural stability and shock absorption during operation.
- Depth Indicator & Safety Devices - Monitors rope position, overload, overspeed, and slack rope conditions.
- Sistema de lubricación - Includes lubricating oil pump station and pipelines, ensuring proper lubrication of moving parts such as gears and bearings.
【Principio de funcionamiento】
During operation, the variable-frequency motor drives the reducer through an elastic coupling, utilizing a two-stage helical gear transmission to reduce speed. The rotation is then transferred to the drum via a drum gear coupling, ensuring smooth and efficient power transmission.
The brake control system precisely manages the motor's forward/reverse rotation and speed adjustment, enabling intelligent winding and unwinding of the wire rope to perform lifting operations. Equipped with closed-loop speed control and real-time travel detection, the system ensures accurate positioning and speed regulation. Additionally, multi-level safety protections (such as overspeed, overload, and emergency braking) enhance operational reliability, making the hoist both efficient and stable in demanding mining environments.
