JZ-16/1000P sinking winch/hoist

Mining hoist winch Applicable scenarios:Inclined shaft material transportation (such as coal, gangue), vertical shaft personnel lifting (explosion-proof model JTPB series must be selected);Suspending hoisting plates, water pumps and other equipment during vertical shaft excavation (load ≤ 160kN)

Maximum static tension of wire rope (kN)：160

Roll diameter (mm)：1000

Wire rope diameter (mm)：40

Winch weight (t)：12

Technical Features:

The JZ-type mine winder adopts controlling the Spindle device: The drum is connected to the gear and brake wheel via copper sleeves and bolts, the spindle only rotates synchronously with the drum without transmitting torque; the wire rope is designed with top-out routing, made of high-strength steel, and the rope capacity can reach 1,800 meters (e.g., JZ-40/1800). Braking system: The working brake adopts a pad brake structure, with the hydraulic pusher releasing when the motor starts and spring braking activated when the machine stops; the safety brake is of floating pad type, which triggers power-off protection by the fall of the heavy hammer to ensure the reliability of emergency braking.

Working Principle Diagram

The spindle device, the hoist’s core load-bearing/working mechanism, bears all torque, winds steel wire ropes and resists static, dynamic and special loads. It comprises a 45# carbon steel spindle (two non-destructive tests), domestic HRB/ZWZ/LYC bearings, drums, liners and high-strength bolts; no extra keyways guarantee strength and safety.

Drums are 16Mn low-carbon alloy steel-welded (diffused deformation, non-concentrated stress), with post-welding aging vibration to eliminate internal stress. 16Mn brake discs resist deformation/wear; split types (factory-finished) are ready for on-site installation.

Double-drum hoists use radial gear block hydraulic rope adjustment (console-controlled); hydraulic clutches enable fast, reliable adjustment via spindle/movable drum rotation.

Three drum structures: 1. Integral (drum + brake disc welded); 2. Integral (two-piece split brake disc bolted); 3. Split (two/four-piece drum + two-piece brake disc bolted).

The spindle device, the hoist’s working mechanism, bears all lifting/lowering torque and steel wire rope tension on both sides of the friction wheel. It comprises a high-quality low-alloy steel spindle (bears self-weight, external loads and transmits torque, with forged flanges bolted to the friction wheel), friction wheel, rolling bearings, bearing blocks, covers, beams, friction liners, fixing and pressure blocks. The integral low-alloy steel welded friction wheel has a shell, webs, hubs, support rings and rope guards; large hoists (diameter ≥2.8m) have internal support rings for rigidity. Brake discs are welded (drum-end) or detachable split (bolt-connected) as needed. Main bearings are HRB/ZWZ/LYC double-row spherical roller bearings (good alignment, high load-bearing, impact-resistant, long-life, easy maintenance). Friction liners (friction coefficient ≥0.25) are bolt-fixed; floor-mounted hoist liners have two rope grooves, with a shifting device to double life and utilization.
