Different speed electric hoist

1.Introduction

CD or MD type electric wire rope 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:Why do prefabricated components need tower cranes
Patent technology production of phosphating coating steel wire rope, preferred department or zinc manganese phosphating, compared with smooth steel wire rope production process, only increased the final wear-resisting phosphating process, the wire rope greatly improve wear resistance and corrosion resistance, using phosphating steel twist wire rope directly. The fatigue test data show that the phosphating coating is smooth with structure wire rope fatigue life of wire rope around 3-4 times (lab) under the condition of comparable with the study of wear resistant phosphating formula, there is the possibility of significantly increase.
Q:The models of the self-elevating tower crane. What is the maximum lifting torque
The torque of the tower crane is set by the factory and cannot be changed. How do you want to convert?I hope my answer will help you..
Q:Where should the crane be set up?
Entering the bridge crane and the door of the gantry crane and the driver's room to the hatch door of the bridge, the protection device shall be set up. When opened, the crane's operating mechanism cannot start
Q:Where do you need a crane
Logistics loading and unloading, the construction of tunnel engineering, railway track laying and maintenance, oil, chemical, electric power, water, steel, exploration, metering, garden, wharf, ships, municipal maintenance, fire-fighting equipment, national defense construction and other fields.
Q:What does the working grade A1A8 mean
In order to be safe, crane is used for crane operation. Crane working grade Crane work level (gb3811-83) is classified according to crane utilization rating and load condition. Crane use grade The use level is the frequency of the use of the crane in its effective life, and the total number of work cycles is N According to the total number of cycles, the crane is divided into U0 ~ U910. Table 2 is the crane utilization scale. Table 2 crane utilization level Use the rank total work cycle N notes
Q:Safety management certificate of crane (crane) operation certificate
Junior high school graduates can take the exam, the difficulty is not very big. It takes a week or so for the exam to focus on the lessons. In particular, please consult the local special equipment management department or the quality technology department, and also the department under the labor bureau for the training. This response is recommended by Internet users for comment 9
Q:How to ground the crane
Grounding; Crane and all electrical equipment normal not charged metal shell, metal wire tube, cable metal sheath, security transformer low voltage side end shall be reliable grounding.
Q:The weight of the crane is the weight of the lifting and the lifting of the weight.
Rated lifting weight refers to crane allowed to lift heavy objects or materials, together with the spreader (or with) can be divided into the sum of quality (for floating crane, including fixed on the crane hook). Known crane rated lifting weight, by definition, is that kind of situation, depends on whether the crane design allows the main lifting and work at the same time, if allowed, and can lift the two (not the whole machine) and rated lifting weight, is rated lifting weight of the machine is the two together, if not allowed, the crane is the main lifting rated lifting weight. Of course, it's usually the latter. Downstairs said is right, but sometimes, double car bridge crane, for example, if a car rated lifting weight is less than another, you can think is one of the vice hook, such as a 20 t, the other is a 10 t, its representation is 20 + 10, the somebody else, the inspection, as 30 t to consider. I'm thinking about that.
Q:What does the crane main make the controller do?
The main controller is the control unit that crane operator (commonly known as a crane driver) is used to operate manually in the driver's room. The main controller is installed on the platform, the handle part is exposed on the table, the control component parts are in the interlocking box body (prevent the operator's electric shock). Is the role of the main controller driver signal the running speed of the corresponding institutions, through a cable to the agency's control cabinet (or control panel), by the controller to control motor speed corresponding mechanism, thus the purpose of the complete crane control. Most of the main controllers have a set of gear (using CAM assembly principles), and they have a gear (for example, sliding resistance type and photoelectric code type etc.). According to the specification, the control must have a self-locking function to prevent the wrong operation. The master controller has a variety of specifications and types, so I won't go into that.
Q:What is the height of the tower crane?
The installation, disassembling and lifting of tower crane; You have to go through an expert argument
