Rope according to different classification section

Rope hoist rope on the fact, there are many categories, according to the cross-sectional shape of the rope were classified as follows:
Round stock: concentric layers of wire twisted around, stocks approximately circular cross-sectional shape, you can use the same diameter or different diameters of round steel wire or steel wire shaped shaped wire support.
Alien shares: Shares sectional shape is not round, the common shares of a triangular cross-sectional shape, oval, as well as the recent cross-sectional shape of the approximate share held sling shares. The ratio of round stock steel wire rope on the drum anchor big 3-4 times, beaten dense structure, high breaking strength, wear resistance and long service life.
Wire rope hoist Steel Heart type Si Shengsheng
Fiber Heart: support from natural or synthetic fibers, natural fibers generally used jute, sisal, abaca. Has good oil and shock absorption, good flexibility, but the high temperature resistance, poor lateral extrusion, structural elongation greater.
Steel core: the shares or independent wire rope made of wire. Has a large carrying capacity, high temperature resistance, lateral extrusion, impact, structural elongation, etc, but flexibility, fatigue resistance is poor
Solid polymer core: the round or circular grooves with solid polymer support. Has a high elasticity, tensile strength, resistance to acid salt corrosion and compete to squeeze other properties.

Electric hoist motor repair procedure

Hoist motors,  Wire rope hoist  is one of the most important accessories, when the motor problems, motor repair in the understanding of knowledge that we can repair themselves following a brief introduction on the hoist motor repair knowledge, only for your reference:
        Repair hoist motor should be preceded by site cleaned up, ready disassembly tool, and in the end cap and the shell, the joint line, the upper bearing cover and end caps, etc. to be well marked, so as not to confuse a mistake during assembly. Removing  rope hoist  motor steps as follows:
(1) Remove the belt or disengage the connection pin joint oil;
(2) Remove the junction box power wiring and grounding wire;
(3) Remove the pulley or coupling;
(4) Remove the nut and washer foot;
(5) Remove the front bearing cover;
(6) Removing the front cover;
(7) Remove the fan cover;
(8) Remove the fan;
(9) Remove the rear bearing cover;
(10) Remove the rear cover;
(11) out of the rotor;
(12) Remove the front and rear bearings and front and rear bearing inner cover.
Rope hoist motor assembly and disassembly steps in reverse order. In general, a small motor, just remove the fan cover, fan, front bearing cover and the front cover, and then the bearing cover, rear cover with front and rear bearings, the bearing cap and the rotor so drawn together.

The most effective maintenance methods rope hoist

Maintenance on a variety of wire rope, wire rope, but to want long life lubrication reaches you use requirements, general lubrication method had no significant effect, to provide you with the most efficient rope hoist  wire rope maintenance methods:
      Let rope hemp  Wire rope hoist  heart grease to lubricate wire rope, which is by far the most effective method of wire rope maintenance: The main core of the hemp rope grease is heated to 80-100 ° C, would require lubrication after a good dish washing rope soaked in lifting so saturated, so the grease can penetrate into the cord, when the wire rope hoist operation, oil will seep from the overflow at the core rope to rope knots gap which can not only reduce the rope between wire and wire wear, while the rope outside province also has oil, when the operation of electric hoist pulley or drum to reduce friction between extrusion mill loss. Although this operation is a bit cumbersome, but this method is able to maintain the most effective wire rope electric hoist maintenance methods.
Rope hoist with our daily life is closely related to maintenance work, if not long-term maintenance of wire rope hoist rope often will only have to replace one with two or three months, the traditional wire rope coated with grease appearance for viewing rope wear The broken wire and wire checks are unfavorable, to remind you when using wire rope hoist and try not to slag, sand, coal and alkaline substances such as contacts, if any, once stained with the above substances must promptly clean, to ensure the This is the life of wire rope electric hoist much longer.
