Winch (also known as winches) is powered by a human or mechanical reel, reel winding electric winch electric winch pulling rope to complete the work of the unit. Can vertical lifting, horizontal or inclined entrainment weight. Manual winch hoist winch is divided into two kinds of electric. With electric hoist the main. Electric hoist by the electric motor, couplings, brakes, gear boxes and reels, which together mounted on the frame. For lifting height and frequent handling large work situation, speed performance, make empty hook rapid decline. In place of or sensitive materials, use a smaller speed. Common tonnage hoist: 0.5T, 1T, 1.5T, 2T, 3T, 5T, 6T, 8T, 10T, 15T, 20T, 25T, 30T. From the perspective of compliance with national standards: GB hoist winch can be divided into non-standard hoist. Multifunction hoist motor and reel in different positions from each other can be divided into four types: electric hoist electric hoist structure map configuration diagram (1) The motor axis is perpendicular to the axis of the hoist drum using a worm gear md electric hoist, width aspect large size electric hoist specifications, structure bulky, low mechanical efficiency, processing more difficult hoist cabinet, has not produced to the structure type of product. (2) The motor axis parallel to the axis of the mandrel electric hoist electric hoist, the advantage of small size, height and length. The disadvantage is the width of large size packet of manufacture and assembly of complex, large turning radius orbit. (3) The motor mounted on the inside of the drum hoist, the advantage of a small length dimension, compact structure. Its main drawback is the motor cooling conditions are poor, poor packet, inspection, installation, maintenance motor inconvenience, power supply unit complex. (4) mounted on the outside of the drum motor hoist, the advantage for the group, and high degree of common, easy to change the lifting height, easy installation and maintenance. The drawback is the length of large size. md electric hoist | generous heavy (certified) | Hengshui hoist is provided by generous heavy machinery Co., Ltd., Henan Province.
