Product Description
JKB series wire rope pulling hoist with explosion proof function
Introduction of JKB series wire rope pulling hoist with explosion proof function:
JKB series wire rope pulling hoist with explosion proof function is according to the People’s Republic of China’s manufacturing industrial standards of AQ 1035-2007< Safety inspection code of single-rope drum winder for coal mines> GB/T20961-2007 and the Hebi city star mining machinery manufacturing Co.,LTD ’s enterprise standard of Q/HBXG003-2007.2008.2009.2010.2013 to design and manufacture the products.
Application of JKB series wire rope pulling hoist with explosion proof function
JKB series wire rope pulling hoist with explosion proof function adopts to the ground or under the mine’s inclined tunnel and the small model vertical shaft as the lifting material of the coal mine,metal mine and non-metal mine.

Specification of JKB series wire rope pulling hoist with explosion proof function:
Spindle unit
- The spindle is made of high quality 45 # alloy steel forgings. The manufacture of whole forging flange is fixed the problem of running or loosening keyway which caused by positive and negative operation of hoist. It greatly improves and reduces the safety of the hoisting machine and maintenance costs. With two NDT testing, it proceeded. Its carrying capacity and torque were greater than 650KN, and mechanical performance test in accordance with national standards.
- Spindle unit bearing adopts double row centripetal spherical roller bearing. The bearing with high carrying capacity and stable operation.
- The materials of winch drum uses 16Mn and thickness of 30mm steel. After rolled by the bending machine then carefully process (to prevent eccentric), tempering, vibration failure treatment after assembling the roll force more uniform stress better withstand torsional strength greater than 410KN, anti-shock and vibration due to the rope Rally greater than 650KN.
Reducer
- Type: planetary reducer
- The reducer with hardened planetary gear reducer, planetary gear reducer, the sun gear wheel and all sizes are made of carbon steel, carburizing hardening tooth surface grinding, and the tooth surface to meet the standards of accuracy. Carbon steel ring gear using the nit riding treatment, the tooth surface to meet the standards required precision.
- Reducer type: NBD900
- Reducer ratio: I = 31.5
- The inside bearing of planetary reducer adopts domestic famous-brand products. It can be sure of the service time can meet the requirements of related regulations.
- The reducer adopts shaft coupling to connect with winch drum.
Disc brake
- Disc brake with rear fuel tank normally closed type, butterfly spring brake, oil pressure opening gate, the brake is designed braking in the form of anti-designing. When there is no pressure, without electricity, the hoist is being braked and stopped, namely the security state (with nine different directions butterfly spring inside the brake, wearing on dowels with brake shoe, adjust the size of brake disc with the butterfly spring pressure; when the hydraulic pump station feed pressure, the butterfly spring shrink, release brake disc, disconnect pressure, spring butterfly release the pressure freely, hoist will be braked).
- With brake shoe wearing and spring fatigue protection devices.
- Hoist work brake torque and safety brake torque is three times larger than hoist maximum static torque.
- Butterfly spring material shall comply the rules of 60Si2Mn hot-rolled flat steel and coil springs steel.
- Brake shoe use KZ104 asbestos plastic, with strong wear resistance, high friction coefficient, and high braking performance.
Explosion-proof frequency conversion electric control system
ZTK(B)
Composed by KJPT mine explosion-proof and intrinsically safe frequency control devices, KZH-12 mine intrinsically safe FM speeder console and intrinsically safe sensor.
KJPT mine explosion-proof and intrinsically safe frequency control devices input voltage: 380V, 660V or 1140V
Motor power: 37KW-500KW
Maximum output open circuit voltage: 12.5V
Maximum short circuit current: 200mA
This device explosion-proof requirements comply GB3836.1-2000 and GB3836.4-2000 and other standards.
The explosion-proof type of this device is mine explosion-proof and intrinsically safe, marked as "Exd [ib] I".
Intrinsically Safe console
Console is the control center of winch, the manipulation of winch at runtime is controlled by the operating table. Power switch, AC and DC voltmeter, AC ammeter, various manipulation buttons, knobs and LEDs are equipped on the console slant board, In the console horizontal plate, it is equipped with master controller and joystick. The lower part of the handlebars is connected with the work brake mechanism. In the lower part of the console, it is equipped with a foot switch, foot switch and internal electrical lines in the console connected.
Hoist’s running is manipulated by the master controller. Working braking is achieved by operating the handle; Press the foot switch, you can achieve safe braking in emergency situation. Console needs be operated according to the electrical control system’s requirements.
Console basic parameters:
Console Explosion-proof type: Intrinsic safety
Explosion-proof mark: Exibl
a. rated voltage U: DC24V and DC12V;
b. rated current l: 0.5A and 1A;
c. L: 0.1mH;
d. C: 0.1 F;
e. related equipment: KXJ10 / 127 (660) Mine explosion-proof and intrinsically safe programmable control box, connecting cables maximum length is 200 meters, the distributed capacitance C <0.1 F / km, distributed inductance L / 1m H / km
