JTP Series Mine Hoists: Reliable Equipment for Inclined Shafts and Small to Medium-Sized Vertical Shafts

The JTP series mining hoists are one of the core products of Hebi Shuangmin Mining Machinery Co., Ltd., widely used in coal mines, metal mines, and non-metallic mines—both on the surface and in inclined roadways as well as in small to medium-sized shafts—to handle the lifting and lowering of materials and personnel. Backed by robust manufacturing processes and reliable operational performance, this product line has served numerous mining projects across China.

Product Standards and Model System

The JTP series mine hoisting winches are manufactured in strict compliance with the People’s Republic of China’s industry standards for production safety. AQ1033-2007 “Safety Inspection Specification for JTP-Type Hoisting Winches Used in Coal Mines,” a mechanical industry standard of the People’s Republic of China. JB/T7888-2010 “JTP-Type Mine Hoist” and the company’s enterprise standards Q/HBSHM002-2016 Design and manufacturing. Product models cover a wide range of specifications, including JTP-1.2×1.2P, JTP-1.2×1P, JTP-1.6×1.2P, 2JTP-1.6×1.2P, and 2JTP-1.6×0.9P, enabling compatibility with mine‑site requirements across varying depths and production capacities.

Products are divided into JTP type (Non-explosion-proof) and JTPB type (Explosion-proof) Two major configurations. The JTPB model is equipped with an explosion-proof motor and is suitable for underground coal mine environments containing coal dust or explosive gases.

Core Structural Features

Spindle assembly It is a core component of the JTP series, comprising a fixed drum, a movable drum (used only in twin-drum configurations), a main shaft, two bearing housings, and a rope‑adjusting mechanism (also used only in twin‑drum configurations), and is designed to wind or release wire ropes. The drums are engineered according to elastic theory and are fabricated from high‑strength low‑alloy steel. Q345A The shell is made of cylindrical casing material and is available in two configurations: an all-welded type and a split-type with bolted connections, facilitating maintenance or replacement during operation.

Full-rotation transmission design : The spindle is equipped with self-aligning double-row roller bearings at both ends, and all rotating components utilize fully rolling contact transmission, resulting in overall machine efficiency of More than 90% , a energy-saving mine hoisting winch.

Braking system It employs a rear-mounted disc brake with an oil cylinder and electro-hydraulic combined control. Rope-adjusting mechanism A hydraulic axial or radial gear‑block type rope‑adjusting clutch is employed, ensuring precise and rapid rope adjustment.

Working principle

The JTP series comprises a power system, a transmission system, a working system, a braking system, a control and operating system, and an indication and protection system. After the main motor is started, the motor transmits power via an elastic coupling to the high-speed shaft of the reducer; following speed reduction, the power is transferred from the reducer’s driven shaft to the spindle assembly through a gear coupling. By reversing the motor’s direction, the drum can wind or release the wire rope, enabling the hoisting container to perform periodic reciprocating vertical motion within the shaft.

The product is equipped with a depth indicator and an encoder, forming a comprehensive indication and protection system that includes overwind protection and limit‑switch functionality.

Technical Specifications Reference

Taking the JTP-1.6×1.2P as an example, the drum diameter is 1,600 mm and the drum width is 1,200 mm. The maximum static tension of the wire rope varies depending on whether the application involves personnel or cargo. The average lifting speed is approximately 2.6 m/s, with a reduction ratio of 31.5 and an electric motor power rating of 110 kW. For specific parameters, please refer to the actual technical agreement and the product nameplate.

About Shuangmin

Hebi Shuangmin Mining Machinery Co., Ltd. was established in 2009 and is located in the Shilin Industrial Park, Shancheng District, Hebi City, Henan Province. The company is a designated manufacturer of specialized mining equipment and spare parts. Its main products include JTK, JTP, JTPB, JK, JKB, JKM, and JKMD series mine hoists, shaft elevators, multi-rope friction hoists, JZ‑type shaft sinking winches, as well as complete sets of mining equipment and related components such as headframes, crown sheaves, cage cars, skip buckets, and fall‑prevention devices. The company operates a 25,342‑square‑meter production base equipped with 160 pieces of processing machinery, with an annual output of over 500 hoists of various types. Its products are exported to numerous countries, including Germany, Turkey, Ghana, and Tanzania.

The JTP series mine hoists have been successfully deployed in coal, metal, and non-metal mining projects across numerous provinces and municipalities nationwide. In 2024, after conducting an on-site inspection, a Ghanaian customer placed orders for the 2JTP-1.2×0.8 and JTP-1.2×1P mine hoists, and the Shuangmin technical team traveled to the site to provide installation guidance.
