1.Introduction

CD1,MD1 model 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.

The lifting speed of CD1 model electric hoist is common speed, it could satisfy common use requirements, MD1 model electric hoist operates two lifting speeds----common speed and slow speed. When working at slow speed, it could satisfy precise loading and unloading, sand box moulding, machine tool inspection and other precise working requirements. So the use MD1 electric hoist would be much wider then CD1 hoist.

It is equiped with compact structure, convenient adjustment, small volumn, light weight, heavy gravity, easy operation etc.

Q: Does the forklift belong to a crane?
Forklift is not a crane. On January 14, 2010, the general administration of quality supervision, inspection and quarantine (aqsiq) issued a notice on the catalogue of special equipment for the supplement of special equipment. This paper puts forklift into "special motor vehicle in the field", and its equipment code is 5110. In the TSG q7015-2008, the regular inspection rules for lifting machinery, the forklift truck is listed as a small lifting equipment, which is a kind of crane machine. The regular inspection rules of hoisting machinery was carried out on April 1, 2009, and the forklift truck is a small lifting equipment. The notice of the catalogue of special equipment shall be executed on January 14, 2010. So forklift should not be in the management of crane machinery. It is believed that the general administration of aqsiq will clean up the inspection of special equipment and relevant documents, and the relevant problems will be solved.
Q: What effect is the cord in the crane wire rope?
New hemp rope core generally contain 12% ~ 15% of the oil, and scrap steel wire rope in the loss of the largest part only contains 2.4% of fat, on the same piece of wire rope, even without pulley still oil containing 12.7% ~ 14.5%. The experiment shows that the broken wire of the coated steel wire rope is about half of the non-oil. The initial oil content of a wire rope can only last 40 percent of the life span, and then it increases dramatically if not refueling. The second is the use of the steel wire rope with poor environment and relatively low relative motion, which can choose the special wire rope such as galvanized and aluminized aluminum. These cables are exposed in the atmosphere to galvanized or coated with aluminum hydroxide and aluminum hydroxide films, which effectively prevent corrosion of wire rope
Q: The lifting equipment will be monitored once
Article 5 the provisions of article 5 of the regular inspection rules for hoisting machinery issued by aqsiq: The periodic inspection period of the crane machine is as follows: (1) tower cranes, elevators and floating cranes are once a year; The wheel of the wheeled container crane is made up to 1 times every two years.
Q: What is the KBK crane
Installation is convenient, economic and efficient KBK system installation and debugging is very convenient, just bolted connection between profiles and the standard module can be used, and can save space and area of the factory, greatly reduces the human resources, improve the production efficiency, reducing energy consumption, improve the efficiency of the enterprise. System can be manually operation, also can realize the automatic, semi-automatic operation, efficient operation.
Q: What are the specific points of crane A5? How to work?
The level of work is the amount of time you spend on a crane. This level is commonly calculated according to the usage frequency of the usage. Make cranes according to the work level, avoid waste of materials, and use the waste of doing work, more reasonable to meet the requirement of use. Writing so many hopes the landlord see... If you don't understand, you can check the work level of the crane online.
Q: How many times does the crane take every year?
Article 5 the provisions of article 5 of the regular inspection rules for hoisting machinery issued by aqsiq: The periodic inspection period of the crane machine is as follows: (1) tower cranes, elevators and floating cranes are once a year; The wheel of the wheeled container crane is made up to 1 times every two years. (2) the small light lifting equipment, bridge crane, gantry crane, portal crane, cable crane, mast cranes, rail crane, jib crane, once every 2 years mechanical parking equipment, including the lifting of molten metal and hot metal crane 1 time every year. Performance test of the rated load test, static load test, the dynamic load test project, the first test and the first periodic inspection must be carried out, the rated load test program, after 1 inspection cycle 1 time intervals. Inspection process, for there is a significant risk of hoisting machinery, such as special operating environment, frequent accidents, etc.), the inspection institution approved by the provincial quality technical supervision department agree, can shorten the cycle of periodic inspection appropriately, but the shortest period of no less than 6 months.
Q: QD hook bridge crane and LH type gourd double beam crane, what is the difference between using value?
Let me explain it to you! Is there any substantial difference between the two? Substantial difference is unlikely, QD is the car type double beam bridge crane, LH is double beam bridge crane hoist trolley type 2. Hoisting and gourd what are the significant difference between the two? LH assembles double car is to put the lifting mechanism operation integration of a car, usually in small volume, and QD type drum hoist, car brake, brake motor and running mechanism are installed separately, and then assembled into a car that is probably the biggest difference between them! Which is more practical? Who can help me to list the pros and cons? QD car generally used in the workplace are frequent, environment is harsh situation, LH is relatively is not as difficult as QD type car with 4. And what is the difference between the control mode? There seems to be a ball (in the line in his hand, remote control and control (a cab) here to choose which one is better? What are the strengths and weaknesses? Control mode to no difference, the choice of the three ways can! Choose which way it basically is to see your work environment, what do you use your factory, consult the crane manufacturers who can clearly give you choose the way to control!
Q: Is a bridge crane a crane?
Driving generally refers to an ability to lifting and along a fixed orbit hoisting equipment, such as gantry crane, gantry crane (crown), single arm crane, crane should also include stationary and mobile, such as construction machinery of tower crane, hoist, crane, etc. A bridge crane is a type of crane, or a bridge.
Q: How to choose tower crane model according to the height of building?
he building's eaves height is within 20 meters, and the floor space of each floor is 800KN. M tower crane, with an 800KN.
Q: Which electric brakes are used for crane motors?
Second, electric brake. Reverse braking. Reverse braking is the phase sequence that changes the power supply. Energy braking. The energy brake is the stator through direct current. Regenerative braking. Regenerative braking also feedback braking, such as a crane's main hook, which USES regenerative braking.
