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:The construction crane equipment includes which
Light and small lifting equipment such as jack, gourd, hoist and so on. Gantry crane crane, gantry crane, etc. The arm frame type crane, such as fixed revolving crane, tower crane, truck crane, tire, crawler crane, etc.
Q:I was wondering if crane crane ` ` ` `? What is the difference between two?
It's weight is bigger, and can turn 360 degrees in any direction, but needs a leg when hoisting, in order to increase the stability of the crane performance. In the case of not dozen leg work or walking hoisting, need to reduce weight. Must ensure that the road smooth, solid tire air pressure to conform to the requirements of load should be in accordance with the provisions of the original locomotive performance. At the same time the weight lifting off the ground shall not exceed 50 cm, and bolt rope running slowly. Long walk with load is prohibited.
Q:What does the crane mean?
A crane is a large arm that is hoisted on a crane. (it is also called a barpole.) the process of raising or moving down the crane is called a variation.
Q:Why the electric gourd? What is the origin?
The CD1 and MD1 type electric gourd are widely used in factories, warehouses, docks, power stations, logging, etc., which are the ideal lifting equipment for lifting and moving objects.
Q:The lifting equipment will be monitored once
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
Q:What is the working principle of a crane? thank you
Lifting lifting or lifting and moving heavy lifting machine through lifting hook or other fetching equipment. The process of lifting machinery is usually involved in the process of raising, running, lowering and returning. Lifting organization after picking up equipment, weight from the fetch address after the operation, reverse shift weight or range of organizations, in the specified address down the weight come back to the in situ. Drive equipment The drive device is used to drive the power equipment of the job organization. Common drivers are power driven, internal combustion engines and human drivers. Power is the power of clean, economic, electric drive is the primary drive type, modern crane operation over a limited range of rail crane, elevator, the elevator choose electric drive. The use of an internal combustion engine for moving cranes, such as car cranes, tyre cranes and caterpillar cranes, can be moved remotely. Manual drive is suitable for small lifting equipment, as well as temporary power for auxiliary, spare and unexpected (or incident) of some equipment.
Q:Daily maintenance of crane equipment
(5) check whether the fastening screw on the seal of the lifting mechanism is loose and short. (6) to check whether there are foreign objects in orbit that impede the movement of the bridge. (7) to check whether the transmission of the various agencies is normal or not.
Q:What does the crane main make the controller do?
The motor capacity is large and the CAM controller is not enough. (2) the frequency of operation is high, and the number of passes per hour is close to or more than 600 times. (3) the crane is heavy and the operation is very frequent, and the requirement of reducing the driver's labor intensity requires the higher life of the electrical equipment. (4) the crane requires better speed adjustment, point motion and other operation performance.
Q:What is the difference between a tyre crane and a crane
Lifting weight, lifting height, amplitude, load moment and the weight of the whole machine. Wheel crane rated lifting weight by movable arm strength and overall stability limits, according to the amplitude change, in order to prevent overload must be equipped with a torque limiter, crane because of the high speed, flexible, automobile chassis and parts supply convenient wait for an advantage, especially the telescopic jib type crane, developing very quickly. The tyre crane is the further development of the direction of the mobility and cross country ability. Multilateral special-shaped section telescopic boom, box radiant chassis, activity type counterweight, the new wheel crane appear constantly. x0d tyred crane development trend is: large-scale, efficient, safe, and reduce weight, further improve the lifting driving performance and maneuverability. x0d truck crane, truck crane is in a normal car chassis or special automobile chassis of a crane, its driving cab is separated from lifting control room Settings. This kind of crane is the advantage of good maneuverability, move quickly.
Q:The difference between a crane, a crane and a crane
Driving generally refers to the cart and the car of similar type "ten" word or rectangular coordinates in the corresponding projection area of the lifting point. There are also called bridge type crane, beam crane, etc.
