As a relatively common crane category, jib crane mainly include three forms: fixed column cantilever crane, walking cantilever crane, and wall-mounted crane. This article describes different types of jib crane.

Overhead crane is also called bridge crane or eot crane, which is usually divided into single girder overhead crane and double girder overhead crane. The main differences between single girder overhead crane and double girder overhead crane are as follows.

Single girder crane has two modes of operation on the ground and in the air. There are two types of ground operations: wired handle operation and remote control handle operation; air operation refers to cab operation. The driver’s cab has two types: open type and closed type. It can be divided into two types of left or right installation according to the actual situation. Reasons for single girder crane shaking:1. The transmission parts produce wear gaps. For example, the gears of the gear coupling, the gears of the reducer and their joint keys are loose, and the gap between the connecting bolts and the holes of the drive shaft is worn out.2. The wheel binding key is loose.3. A certain wheel does not turn well. Because the backing plate fixing the wheel bearing seat is not correct, the bearing is not clamped flexibly, and the wheel stops first when parking.4. The braking torque of the brakes on both sides of the separately driven cranes is inconsistent. When parking, one brake wheel has stopped, and the other is still rotating.Due to the twisting of the crane, the wheels on both sides rotate accordingly, so that the transmission parts of the crane…

lifting tongs are mainly composition of parts: hanging beam, connecting plate, opening and closing mechanism, synchronizer, clamp arm, support plate and clamp teeth.

Safety monitoring of metallurgical crane in steel mills

Overhead cranes and gantry cranes are used in different working conditions and are widely used in the material handling industry.

The standardized use and daily maintenance of the crane lifting beam can increase its service life and reduce the occurrence of safety accidents.

European style crane is base on the introduction and digestion of internoal advance technologies, guid by the modular design theory, using modern computer technology as a means, introducing optimize design and reliability design methods, and using imported configuration, new materials, and new processes. It is a new type of crane with light weight, generalization, energy saving and environmental protection, maintenance-free and high-tech content.

How to clear the crane sludge is one of the important procedures in the maintenance of lifting equipment. Crane sludge is the sludge formed in the area where dust encounters oil vapor or water vapor during crane operation. There is a risk of spontaneous combustion if the sludge adheres to the crane, as well as accelerated damage or aging of crane components.

Overhead crane is usually use in indoor workshop, warehous, etc. and It is a relatively common hoisting and handling equipment. The working conditions of the workshop will greatly affect the selection of overhead crane. so how to choose an overhead crane suitable for plant conditions? The following Flagcrane will introduce some selection items of overhead crane for you. For workshops without power supply, Flagcrane recommends manual bridge crane.  If the height from corbel to house edge is limited, Flagcrane recommends LX electric single girder suspension crane, LD electric single girder overhead crane and LH double girder electric hoist overhead crane. For the corbels with low pressure, Flagcrane recommends LD electric single girder crane, LX electric single girder suspension crane, and LH electric hoist bridge crane. And if the corbels have low pressure and want a larger lifting capacity of the crane, you can choose Trackless overhead crane. So the above is only the influence of plant conditions on the selection of overhead crane. The specific selection should also refer to factors such as the use environment and the type of lifting materials, so that a more suitable bridge crane can be selected.

The parameters of bridge crane mainly are: lifting capacity, span, lifting height, travelling speed, lifting speed, working class, etc.

Safety Instructions for Overhead Cranes and Gantry Cranes

Cranes belong to special equipment, so safe operation training of cranes can minimize the risk of accidents and protect personal and property safety.

The metallurgical crane is a overhead crane, It mainly includes: casting crane, slab crane, stripping crane, clamping crane, forging crane, quenching crane, electrolysis crane, rake crane, etc. Due to the harsh working environment of metallurgical crane, in order to avoid the failure of metallurgical crane, the following safety measures are designed for metallurgical crane to ensure the safety of users’ personal and property.

In order to further implement the Group’s quality strategy and comprehensively improve product quality, Flag Crane has formulated a series of measures to improve product quality to better serve customers and lay a solid foundation for product quality improvement. First, it is necessary to strengthen the quality awareness of employees ideologically, and secondly, continue to maintain the pretreatment of steel and profile shot blasting to improve the appearance quality of materials and the adhesion of paint. Thirdly, do a good job of self-inspection. When cutting materials, carefully follow the work order and the drawings; after cutting, check the drawings first, and then carry out appearance treatment such as slag cleaning, so that each piece of material can be Meet the quality requirements. Finally, carry out random inspection or special inspection on the materials. In this way, every layer of material used in the production is a qualified product, and the quality improvement work of the first process is done for the team. In fact, no matter what the situation and conditions are, Employee is a key factor, the staff is the main body of the machine management , the human determines the quality, and the quality is a kind of responsibility cultivation. As…

Over the years, Flagcrane has continuously increased its transformation and upgrading efforts, broadened its product business scope, and improved its R&D and manufacturing capabilities for high-end and non-standard products such as European-style products, large-tonnage, heavy-duty road overhead cranes and gantry cranes, breaking the previous single product type in one fell swoop. , R&D and design lag and other inherent modes of low-end manufacturing. The company’s Europe Type Double Girder Crane adopts an integrated control cabinet. All external wiring adopts aviation plugs. Siemens SMART200PLC communicates with touch screen for status monitoring and fault display. The whole vehicle adopts Europe style structure. Frequency conversion control and hoisting closed loop achieve high-precision control, four-speed rocker control, etc. In addition, Europe Type Double Girder are accepted by the market due to their relative advantages such as small occupied space, light weight, overall flexibility, high work ability, low failure rate, convenient maintenance, safe operation, and advanced technology. When using Europe Type cranes, the hook upper limit has been greatly improved . The size of the hook to the top edge is infinitely compressed, which greatly reduces the distance from the hook head to the bottom of the workshop, increases the lifting height, and reduces energy loss. Double rim…

New motivation! New upgrade! With the large-scale introduction of high-precision equipment by Henan Flag Crane Production and R&D strength continues to increase Several automatic drum tooth production lines were put into use “Drum Gear Coupling” Innovation in a small accessory Greatly improve the quality and service life of crane products 01 product description: The drum gear coupling belongs to the rigid-flexible coupling, which has the ability to compensate the axial deviation of radial, axial and angular directions. Drum-shaped tooth couplings are widely used at home and abroad as a common coupling for heavy-duty shaft transmission. 02 Features: 1. Strong carrying capacity. Under the same outer diameter of the inner gear sleeve and the maximum outer diameter of the coupling, the bearing capacity of the drum gear coupling is on average 15-20% higher than that of the straight gear coupling. 2. Large amount of angular displacement compensation. Under the same modulus, number of teeth, and tooth width, the angular displacement of the drum teeth is larger than that of the straight teeth. 3. The drum-shaped tooth surface improves the contact conditions of the inner and outer teeth, improves the friction and wear conditions of the tooth surface, reduces the noise, and…
