JKZ/2JKZ Mine Shaft Drilling Hoist
- Type: JKZ is a single-drum mine shaft drilling hoist, suitable for small to medium-sized mines. 2JKZ is a double-drum mine shaft drilling hoist that supports simultaneous hoisting of two containers and is suitable for deep shafts or high-load scenarios.
- Application: JKZ/2JKZ type shaft hoists are large-scale hoisting equipment specifically designed for mine shaft development and ore hoisting. They are particularly used for the vertical transportation of personnel, soil and rock waste, construction equipment, and lining materials during shaft construction.
Introduction Of JKZ/2JKZ Mine Shaft Drilling Hoist
The JKZ/2JKZ mine shaft drilling hoist, also called the JKZ/2JKZ shaft sinking hoist, or JKZ/2JKZ well drilling hoist, is a heavy-duty, specialized hoisting equipment designed for the shaft-sinking stage in mines. It belongs to the single-rope winding hoist category, with the JKZ featuring a single-drum configuration and the 2JKZ a double-drum configuration. It is widely used for material and personnel transport in deep mines such as metal and coal mines. The product design strictly adheres to mining industry standards and has passed national-level mining product safety certification. The core function of the JKZ/2JKZ mine shaft drilling hoist is to undertake the vertical transport of personnel, soil and rock materials, construction equipment, and lining concrete during shaft construction. It has a maximum static tension of 590kN and a maximum rope capacity exceeding 1500 meters, meeting the hoisting needs of shafts up to 1000 meters deep or even deeper.
Types Of Mine Shaft Drilling Hoist
- The JKZ single-drum mine shaft drilling hoist is suitable for small-diameter vertical shafts and projects with flexible schedules, offering lower procurement and maintenance costs.
- The 2JKZ double-drum mine shaft drilling hoist can control two hoisting containers simultaneously, increasing efficiency. It is suitable for large-diameter vertical shaft sinking projects with tight schedules. For ultra-deep wells over 600 meters, the double-tube model offers higher safety.
Unlike conventional mine hoists, the JKZ/2JKZ mine shaft drilling hoist is designed to withstand large load fluctuations during construction, high-speed control precision requirements, and frequent relocation and disassembly after the work cycle. Therefore, its design balances heavy-duty reliability with modular assembly and disassembly convenience. It can be used in traditional mining infrastructure scenarios such as coal mines, metal mines, and non-metal mines, and can also be adapted to the special needs of emerging fields such as urban underground space development and deep energy storage shaft construction. This mine shaft drilling hoist adopts a modular design, supporting customized configurations to meet the depth, speed, and load requirements of different mines. In addition, we also offer the JKB explosion-proof mine hoist, which can adapt to special underground working environments such as high gas and high dust levels.
principle & structure Of JKZ/2JKZ Mine Shaft Drilling Hoist
Working Principle
The JKZ/2JKZ well drilling hoist adopts an operating logic of “electric drive – mechanical transmission – electro-hydraulic coordinated control”. After startup, the main motor outputs power to the reducer via a flexible coupling, and after reduction and torque increase, drives the main shaft and drum to rotate. It mainly uses the winding and unwinding of the wire rope on the drum to pull and lift the container, thereby realizing the up and down lifting of the bucket, skip, or cage.
Structural Features
- Drum assembly: High-strength steel drum, accommodating multiple layers of steel wire rope, with wear-resistant surface treatment.
- Head sheave and guide sheave: Optimize the wire rope deflection angle and reduce wear.
- Power reduction system: Includes drive motor and high-efficiency reducer. Custom parameters can be set to achieve efficient power transmission and torque amplification, ensuring stable operation under heavy load conditions.
- Electrical control system: Utilizes variable frequency speed control technology to achieve smooth start-up and precise positioning.
- Electrical control cabinet: integrates PLC and touch screen, supports fault self-diagnosis and energy consumption statistics.
- Braking system: Equipped with hydraulic disc brakes and redundant backups to ensure emergency braking in the event of a sudden power outage.
why choose JXSC JKZ/2JKZ Mine Shaft Drilling Hoist
features & Advantages
- Strong adaptability to heavy loads: The high torque design can adapt to large load fluctuations during the construction phase, and supports 24-hour continuous operation under rated load without the risk of overload.
- High control precision: Variable frequency speed regulation combined with closed-loop position monitoring meets the requirements for precise material feeding and equipment hoisting.
- High safety redundancy: The braking, hydraulic, and electronic control systems all adopt redundant design, and multiple safety protections respond quickly.
- Flexible customization: The mine hoist can be configured with explosion-proof, low-temperature-resistant, and corrosion-resistant mining shaft sinkers and hoists to adapt to special operating environments such as high-gas mines. Differentiated configuration solutions are available based on well depth, speed, and application.
- Wide range of applications: Standard JKZ/2JKZ mine shaft drilling hoist models cover 300-1500 meters, and can be extended to over 2000 meters by customizing steel wire ropes and motor power.
- Easy to use: Modular structure design allows for quick replacement of key components, adapting to rapid site relocation needs.
- Low maintenance costs: Variable frequency control can save energy and reduce long-term operating costs. Anti-corrosion coating and sealing design result in an extremely low failure rate and an exceptionally long lifespan.
- Stable operation: The entire process is automatically controlled by a PLC and can be integrated with remote monitoring functions to reduce the risk of human operation.
