CD or MD type wire rope electric hoist is a kind of light type lifting equipment. It could be installed on single girder crane with hoist, overhead,gantry and jib crane. Modified could be used as a winch. So it is a commonly used lifting equipment in factory, mine, port, warehouse, cargo yard, shop etc, is a nessesary equipment to improve working efficiency and labor conditions.

Q:What is the grounding resistance of the new crane crane?
Ground resistance is 0.5 o, because the new car insulation resistance should be above 200 megaohm. The deflection should be the hogging of the empty load and the difference of the arch degree after lifting the load rating.
Q:A crane (a big lift in a building) who knows.
Tower crane beam and the stents cross which is below the control room, is a structure similar to the casing, connected to the beam size is greater than the support structure of steel column, is set on columns. Usually below the casing structure, there will be a circle of platforms for workers to stand. In the lower part of the casing, the casing is fixed to the bottom of the casing, not only the connection between the two structures, but also the upward support. In other words, the top of the pillar is not supported. The pillar is made up of a section of steel, which is connected by a large riveting, which is a section of a steel component of 45 degrees. And casing structure usually has section 2.5 is so high, but the connection is only lies in the following section, so the casing can rise to the most in the previous section, and will not rise to stable. When the casing up to the top section, in the bottom of the casing and pillar top there is more than a quarter of the space between, then, can lift the new section, and placed it in the space. The new section, which is neither heavy nor connected, holds it to the top of the pillar. And then the casing can keep going up. Actually this new section is on the rise before hanging up, and there at the bottom of the casing structure, equipped with two slide rail, a new section can hang in the above, when the space is enough, a worker can take it advance along the slide rail. The casing and its connected beams are also heavy,
Q:The difference between a crane, a crane and a crane
Crane is a general term, including above, and there are other special categories such as cantilever, self-propelled hoist, self-car, etc.
Q:The tower crane QTZ125 is a few tons
Nominal lifting torque KN m 1250 Rated crane torque KN m 1300 The maximum weight is t 8 Work range M 3 ~ 60 The maximum rated weight is t 1.5 Maximum lifting speed m/min 80 The lowest stable rate of descent is equal to 7 Lifting performance is up to m/min 80, 405.6 So it's t 2, 4, 8 The quadruploid rate rises m/min 4020 2.8 The weight t 4, 8, 8 M/min 52/26/8 R/min 0.63 Rise high independent m 50 Attached type m 170 Designed weight t 42.7 (independent height) Balance t 21.2
Q:Is the lifting equipment in the factory the driving or the vehicle?
The driving It's a crane that can be taxied in orbit.I hope my answer will help you.
Q:Can you tell me what procedures you need to move the crane?
The qualification of the crane is installed, and the quality inspection and maintenance qualifications of the special equipment issued by the bureau of quality supervision and administration shall be required to be operated by the quality supervision bureau.
Q:What types of cranes are there
One, lifting machinery is divided into three categories: light and small lifting equipment, crane and elevator. (1) small lifting equipment mainly refers to the lifting mechanism of only one lifting device. There are jack, block, electric manual gourd and so on. (2) a crane is a lifting machine that can be lifted vertically and can be carried horizontally. Such as a bridge crane (also known as a crane or a skycar), a car crane, a tower crane, etc. (3) the elevator points to the fixed position of the lifting machine, the lifting line is fixed, the hoisting of the wire rope, the use of the sliding rail, and the lifting mechanism of the cage. Including elevator, hoist, winch and so on.
Q:The site of the daily inspection of the bridge crane has those
check on the nut, split pin, positioning plate brake whether complete, loose, lever and spring no crack, the pin on the brake wheel bolt and buffer gasket is loose, and complete; The brake is reliable. The brake block should be less than 1.0 mm when the brake is opened and should be equal to the distance between the two sides of the brake wheel. 2) check the safety protection switches and limit switches to be accurate, flexible and reliable, especially if the rising limit is reliable. 3) check the drum and wire rope winding on the pulley is normal, the presence of groove, channeling, knot, the phenomenon such as distortion, wire rope clamp bolt fastening, whether is there a double nut locking device. 4) check that the fastening screws on the shaft of the lifting mechanism are loose and short. 5) check whether the transmission is normal or not. 6) check for good lubrication of all lubricants. 7) check if there are foreign objects in orbit that block the bridge.
Q:What wind protection devices should be set when working in the open air?
For crane in the outdoor work, should be set rail, anchor device or iron shoes, and must be able to separate non-work state under the maximum when the wind doesn't blow down.
Q:What are the safety features of single-beam bridge cranes?
I don't know, it should be important.I hope my answer will help you
