2JK
Double-drum Single-rope Mine Hoist
2JK is a double-drum, single-rope winding hoist family for vertical and inclined mine shafts. A motor and reducer drive the drums, while hydraulic and electrical controls operate the disc brakes and monitoring systems.
Built around your working task.
Review the model and technical reference together with your application requirements. Provide shaft and winding arrangement, load, lifting distance, rope requirements and control specifications. Confirm the exact variant with the technical team.

Check the operating conditions.
Provide shaft and winding arrangement, load, lifting distance, rope requirements and control specifications. Confirm the exact variant with the technical team.
Check the current technical sheet against the configuration in the quotation. Dimensions, interfaces and operating requirements should be confirmed before planning the installation.
How the double-drum winding system works
The 2JK mine hoist family uses two rope-winding drums in a single-rope winding arrangement. A motor drives the drums through a reducer to raise and lower the conveyance. Electrical controls regulate speed, while hydraulic and electrical systems operate the disc brakes and depth indication reports conveyance position.
The source describes applications in vertical and inclined mine shafts. A complete hoisting inquiry needs the actual shaft and conveyance arrangement, not only a desired motor power. Provide the lifting duty and request an engineered model selection for that duty.
Read the variant rather than mixing series maxima
The 2JK designation identifies a family with several drum diameters and widths. The source example 2JK-3.0 × 1.5P describes 3.0 m drum diameter, 1.5 m drum width and variable-frequency speed regulation. It is an example configuration, not the specification of every 2JK hoist.
Static tension and static tension difference are distinct fields. Keep them with the correct drum and rope variant when reviewing the table. Do not combine the largest value from each row to describe a single machine, or convert the tension figures directly into an unsupported payload claim.
Prepare the hoisting-system specification
Share the shaft layout, lift distance, conveyance details, rope requirements and proposed operating cycle. Include the available power supply and control requirements. Ask for a matched selection table, system drawing and scope of supply, including the specified controls and monitoring equipment.
The reviewed material contains an anomalous weight entry and historical standard references. Weight and any required current approvals need confirmation in the offered configuration. This family overview provides a starting point for a technical inquiry; it does not replace the engineering of the shaft system.
Selection questions
What should I include in a product inquiry?
Provide shaft and winding arrangement, load, lifting distance, rope requirements and control specifications. Confirm the exact variant with the technical team.
Which technical details need confirmation?
Values are grouped by drum-diameter variant and must not be mixed across configurations. Request a model-specific selection sheet. Equipment weights are omitted pending confirmation.
How do I request the selected configuration?
Send the model or series reference and your project requirements through the inquiry link. Include drawings or the existing equipment reference where available.
Can the largest listed tension be used for any 2JK drum?
No. The tension, tension-difference and rope references belong to particular variant groups. Request a complete model selection for the shaft duty and keep the associated values together.
