The points should be noted during the operation of the boom crane

As a common crane equipment, the cantilever crane must have a strict posture and careful observation during use to avoid accidents and reduce costs. electric cable hoist manufacturer Therefore, the following points should be noted during the operation of the boom crane:

1.Sometimes in order to protect the equipment on the cantilever crane from corrosion, it is necessary to periodically accumulate the polymer on the track and apply some anti-rust oil. The operator of the jib crane should strictly abide by the operating procedures. No-load operation should be carried out before each use of the cantilever crane, and it is checked whether the rotation, operation, lifting, limit and other mechanisms are normal. If an abnormality is found, the machine should be shut down for inspection before it can be used.

2.In the cantilever crane, it is not allowed to tilt and lift heavy objects. It is forbidden to use the hook to drag heavy objects along the ground or forcibly lift the buried heavy objects. It is also not allowed to use the local swivel arm to drag or hit the work.

3.The bumper or baffle at both ends of the cantilever I rail is used only for unrestricted positions. It is not allowed to be used as a normal parking method during normal operation and is not suitable for frequent collisions.overhead crane supplier

Also in the jib crane, after the operation is completed, the weight should be removed to avoid deformation of the mechanism for long-term suspension. In addition, the following stations are strictly forbidden during operation and some devices are installed to avoid accidents during construction.

The development of lifting machinery

With the rapid development of the economy, in the construction of the project, it is becoming more and more complicated, and the increasingly complex requirements of the crane engineering are getting higher and higher, which puts higher requirements on the design and manufacture of the lifting machinery. The rated lifting capacity of many types of cantilever cranes (spindle cranes) is constantly refreshed.mining machinery for sale

The development of lifting machinery

The product life cycle is shortened, cranes are upgraded, and crane delivery expectations are increasing. In order to meet the diversification and individualization requirements of users, the ability of enterprises to develop new products is getting stronger and stronger, and the development cycle of boom cranes is greatly shortened. Due to the application of new technologies, the crane’s manufacturing cycle and life cycle are shortened, which speeds up the replacement of cranes. Diversified production methods.

With the diversification and personalization of user needs and product delivery requirements, some companies need to adjust production methods to meet the needs of different users. The driving method of the cantilever crane running mechanism can be divided into two categories: centralized driving, that is, one motor drives a long drive shaft and drives the driving wheels on both sides; the other type is driven separately, that is, one on each side Movable wheel motor drive.

Small and medium-sized bridge cranes use a “three-in-one” drive, in which the brakes, reducer and electric motor are combined. Ordinary heavy-duty bridge cranes are easy to install and adjust, and the drive unit usually uses a universal joint. Frequency control is to achieve speed control by changing the synchronous frequency of the motor stator to change the synchronous speed. In order to make the power frequency of the asynchronous motor variable, the frequency converter should be used. The frequency converter is a power supply device that converts constant voltage and constant frequency power into variable voltage and frequency conversion.overhead crane supplier

The control mode of the inverter is divided into open loop and closed loop control, which can be selected by the user. Variable frequency speed control electronic control equipment programmable and optional power line switch, line contactor, auxiliary switch, auxiliary relay and so on.

The kbk track constitutes

The kbk track constitutes the key equipment of the KBK crane and its main function is for the operation of the crane. Tracks consisting of suspensions, tracks, ballasts, vertical lines, and turns! If you find a danger of personal injury or a risk of damage to the equipment, immediately press the emergency stop button and then cut (cut open; cut off) the crane power. Emergency shutdown should also be carried out immediately if the crane fails as follows: damage to electrical equipment, cables and insulation materials; failure of brakes and safety devices.bridge crane for sale

The kbk track constitutes

After the crane is in emergency stop, if the following conditions are met, the equipment can be restarted: the cause of the fault has been eliminated, and the damaged machine has been replaced; the equipment will continue to work without causing other hazards.

Stop using the crane after work. The working strength of the cantilever crane is light. The crane consists of a column, a rotary arm rotary drive device and an electric hoist. The lower end of the column is fixed on the concrete foundation by anchor bolts. The cycloidal pinion reduction device drives the cantilever rotation. The electric hoist is in the cantilever. The word steel runs on the left and right lines and lifts heavy objects. Move the crane unloading load to the specified position, lift the hook to the position and press the emergency stop button to cut off (cut open; cut off) the crane power.

KBK track maintenance stops using the crane. The suspension crane can be simply hung on the roof or superstructure of the building. The crane track does not require additional auxiliary support. It can be installed simply and reliably, at a lower cost, whether it is part or all of the workshop. The single-beam suspension crane consists of KBK standard components, enabling you to quickly and reliably achieve material handling in specific areas and precise positioning of various components.mining machine manufacturers

Large lifting capacity: 1000kg Large span: 6m. Remove all loads and additional loads, cut (cut open; cut off) the power supply and lock the power switch box with a padlock (locking beam) to prevent unauthorised power supply.

Light and small crane reducer oil leakage

1.too much fuel: During the operation of the reducer, the oil pool is stirred a lot, the oil splashes everywhere in the machine, if the amount of fuel is too much.mining machinery for sale

2.A large pressure difference occurs inside and outside the reducer: during the rotation of the reducer, the friction of the motion is affected by the external environment temperature, so that the temperature of the reducer rises too high. If there is no venting place, etc., the crane machine The internal pressure gradually increases, the internal temperature of the machine will also increase, and the pressure difference between the small crane and the outside will be larger. The lubricating oil leaks from the gap under the pressure difference.

Light and small crane reducer oil leakage

3.the speed of the engine leakage is not reasonable.

1) Check that the hole cover is too thin, the tightening bolt is prone to deformation, and oil leakage from the contact gap;

2) During the manufacturing process of the reducer, the castings are not subjected to aging treatment or annealing, the internal stress is not eliminated, deformation is inevitable, and gaps are generated, resulting in leakage;

3) There is no design oil return tank on the tank, and the lubricating oil accumulates in the end cover, the shaft seal, the light and small crane minus the joint surface, etc., and leaks from the gap under the pressure difference;overhead crane supplier

4) The design of the shaft seal structure is unreasonable. In the early stage, the oil reducer and the felt ring type shaft seal structure were mostly used, and the felt was compressed and deformed during assembly, and the joint surface gap was sealed. If the journal is not ideally in contact with the seal, the seal will fail in a short period of time due to the poor compensation of the felt. Although there is an oil return hole in the oil groove, it is easy to block, and it is difficult to exert oil returning effect.

Something about the cantilever crane

According to the type of operation, the cantilever crane is generally divided into ground operation (called ground operation) and operation room operation (called air operation); electric single beam crane, electric suspension crane, crane double beam crane, jib crane and crane door type The electrical system of the crane electric hoist and other equipment used is composed of a power supply introduction device, a vehicle operation control box, and an electric hoist control box. Cart limit switch, lift limit switch, control button (adding remote control panel and receiving when remote control operation) equipment; due to different control methods,port crane,airlift cranes also add speed control resistors, cam controllers, etc.; General crane electrical installations are performed by professional electrical technicians at the equipment installation site.

Something about the cantilever crane

The manufacturer only determines the length of the cable and connects the copper wire nose (if needed) to the cable. The remaining wires can only be cut in the field; then the wires are connected one after the other to the terminals of the electrical components or motors. Due to the installation environment, test methods and restrictions on the installation equipment, the cable connection and precision are often poor, resulting in poor impact resistance of the line. It is not good for multiple commissioning and installation, affecting crane installation time and performance waste, but also for equipment or The motor caused serious damage.

When replacing crane electrical components, repairing wiring or replacing cables and wires, the skilled person still needs complicated and cumbersome complex line measurement and repeated installation processes. Many special tools are required during the installation process. Fire-extinguishing switch problem The fire-extinguishing switch is a safety protection device used to cut off the main circuit power of the crane when the electric hoist is lifted to the limit position, but the installation and debugging is troublesome, and it is difficult for the electrician to perform; and the core guide rod for reliability Both the rope guide and the rope guide need to work properly, but in the case of many lifting hooks (ie, the hook hits the lifting drum cover), the accident is basically due to the lack of a rope guide.mining machine manufacturers

The new type of connection device currently produced has no problem in meeting the electrical system connection of a cantilever crane with a weight of less than 20t. The effective benefit of the realization is to achieve a standardized interface for all electrical units, to achieve fast, reliable and accurate quick connection of the electrical system, without the need for professional electrical technicians to install and replace the circuit, saving the crane a large degree of electrical installation costs, electrical line replacement Time and technical human resources. Installing and replacing the crane’s electrical appliances is as simple as using a household appliance.

There Is Hope For Bunion Sufferers

Hydraulic cranes are available in all kinds of types and models, each with a particular purpose. Petrescu, Relly Victoria; Aversa, Raffaella; Akash, Bilal; Corchado, Juan; Berto, Filippo; Mirsayar, MirMilad; Apicella, Antonio; Petrescu, Florian Ion Tiberiu; 2017e Our Universe, Journal of Plane and Spacecraft Know-how, 1(1). Some helicopters make the most of alternate antitorque controls rather than the tail rotor, such as the ducted fan (known as Fenestron or FANTAIL), and NOTAR.

During the Leyte Marketing campaign, at the Battle off Samar, the Japanese Heart Power of cruisers and battleships, including Yamato, the biggest battleship ever constructed, met the US process drive of escort carriers and destroyers known as “Taffy 3”. The escort carriers and destroyers weren’t anticipated to put up much of a struggle in opposition to main huge-gun warships.

Later in the battle, escort carriers were a part of hunter-killer groups which sought out submarines as an alternative of being connected to a selected convoy. Within the Battle of Tsingtao, from September 5, 1914 the Imperial Japanese Navy seaplane service Wakamiya performed the world’s first naval-launched air raids from Kiaochow Bay. A post-war alternative for each plane, the Supermarine Seagull, was cancelled in 1952, with only prototypes being constructed.gantry crane manufacturer

In 1885, Thomas Edison was given US$1,000 by James Gordon Bennett, Jr., to conduct experiments towards growing flight. In a related article title “Metal on metallic,” “Hoist Magazine” spoke to several suppliers and users of overhead lifting tools within the U.S. plating and galvanising industries. They’ve an unequaled ease of rolling: your operators will discover and revel in immediately the distinction towards standard gentle cranes.

The bridge cranes are used within the initial construction of paper machines as a result of they make it simpler to install the heavy forged iron paper drying drums and different massive tools, some weighing as much as 70 tons. In 1876 Sampson Moore in England designed and equipped the first ever electrical overhead crane, which was used to hoist guns on the Royal Arsenal in Woolwich, London. A helicopter is a sort of rotorcraft in which elevate and thrust are provided by one or more engine-pushed rotors.

Magazine protection was minimal compared to fleet aircraft carriers. Advantages include higher hook protection and it can be designed to hold from your constructing construction on new buildings. Overhead bridge cranes will also be outfitted with anti-collision units to maintain them from colliding with cranes in the identical bay or end stops.
