? Hoist information is introduced in detail ? Hoist (also called winch) is driven by human or mechanical power drum, winding ropes to complete the traction device for work. Can be vertical, horizontal or inclined pulling heavy objects. Divided into manual hoist and electric hoist winch. Now is given priority to with electric hoist. By electric hoist motor, coupling, brake, gear box and drum, installed on the frame together. For hoisting height and cart big job frequently, speed control performance is good, to be able to make a rapid decline in empty hook. To install in place or sensitive material, with small speed. Introduction to the Common hoist tonnage are: 0.3 T 0.5 T hoist winch hoist 1.5 T 1 T hoist 2 T hoist with 3 T winch T 5 T T hoist winch 6 8 hoist 10 T hoist winch 15 T T hoist 20 T 30 T hoist winch. From the Angle of the compliance with national standards: hoist can be divided into national standard hoist, non-standard hoist. Gb hoist winch refers to meet the national standards, non-standard hoist is refers to the manufacturer to define their own standard of hoist) usually only has in the production of the manufacturer can produce gb hoist, the price is more expensive than a non-standard hoist. Common hoist model are: 1, JK0.5 JK5 single drum hoist fast 2, JK0.5 JK12.5 single roller slow winch 3, JKL1.6 - JKL5 humping type fast hoist, JML5, JML6, 4 JML10 humping type pile with hoist jk2 6 and 2-2 JML10 double-drum hoist type 7, JT800, JT700 explosion-proof hoist 8, JK0.3 JK15 electric hoist 9, JM0.3 JM50 10, non-standard hoist electric hoist Including Jk says rapid winch, jm said slow hoist, explosion-proof hoist, jt said single drum said a drum for wire rope, double drum said two rolls for wire rope. A special hoist model are: hydraulic hoist Compared with the traditional electric hoist, electric hoist), hydraulic winch, hydraulic winch) has many advantages: 1. The overload protection 2. The impact protection 3. Explosion-pro
