15 What is the minimum size of an overhead crane needed for 5 ton heavy loads?

The weight of a 25-ton crane should be about 334 tons, and the weight of the 25-ton model of Sany is close to 35 tons, and it may be close to 40 tons if the counterweight is added.

For the sake of crane stability, the manufacturer is designed to be greater than the maximum lifting weight of the crane itself, but under the premise of satisfying the stability of the crane, the smaller the self-weight design, the better, but the weight itself is still greater than the lifting weight.

Zoomlion 25 tons with a self-weight of 30 tons, 16 tons with a self-weight of 23 tons, and 50 tons of self-weight.

A B certificate is required during the crane driving process, but a crane operation certificate is not required. The crane cannot be operated while driving on the road. The crane needs a crane operation certificate when working, and generally those who have this certificate have a vehicle driving B license, and the certificate in operation is different from that when driving.

Driving a motor vehicle requires certain driving skills.

If you lack this skill, if you drive a motor vehicle at will, you may have a traffic accident, and ordinary people cannot drive on the road without a license. However, for those who already have the skills to drive safely, and they drive a vehicle on the road, this permissible document is called a "driver's license". This shows that a driver's license is a kind of "proof of permission".

It depends on what brand, generally domestic production, XCMG 4 arms, 5 joysticks, Steyr engine, car weight tons.

Traction with steel cable, the length of the steel cable is equal to or greater than the length of the bridge, the gun truck passes first, and the gun car passes behind the steel cable Traction, the gun truck passes first, and the gun car passes behind the gun Isn't it just driving the gun truck to cross the bridge, and the gun car can pass by not exceeding its bearing capacity.

It can lift up to 50 tons.

Crane is the common name of crane, crane is a kind of lifting machinery, is a kind of cyclic and intermittent movement of machinery. A working cycle comprises: the retrieval device lifts the item from the fetch place, then moves horizontally to the designated place to lower the item, and then performs a reverse motion to return the fetch device to its original position for the next cycle.

Such as fixed slewing cranes, tower cranes, truck cranes, tires, crawler cranes, etc.

Multi-action lifting machinery that lifts vertically and carries heavy loads horizontally within a certain range. Also known as a crane. It belongs to material handling machinery. The working characteristics of the crane are intermittent movements, that is, the corresponding mechanisms for reclaiming, moving, unloading and other actions in a working cycle work alternately.

The 50-ton crane refers to the maximum that can lift 50 tons, that is, it can lift 50 tons without the boom stretching out, and the weight of the crane is related to the following aspects:

The length of the boom telescopic, the longer the boom is extended, the smaller the lifting capacity;

luffing, the greater the angle of luffing, that is to say, the higher the lifting height of the boom, the greater the lifting capacity;

The angle of lifting, the larger the angle, the greater the lifting capacity.

It can lift up to 50 tons.

50 tons of crane refers to 50 tons for the rated lifting capacity of the crane. The rated lifting capacity is the sum of the materials that the crane can lift together with the divisible spreaders or attachments (such as grabs, electromagnetic chucks, balance beams, etc.).

The common sense of the crane is as follows:

1. The lifting capacity marked on the crane sign usually refers to the rated lifting capacity of the crane, which should be conspicuously displayed in the obvious position of the crane structure.

2. For the boom type crane, its rated lifting capacity changes with the amplitude, and its lifting characteristics are characterized by the lifting moment. The value indicated on the signage is the maximum lifting capacity.

3. For cranes with separable spreaders (such as grabs, electromagnetic chucks, balance beams, etc.), the total service of the spreader and material quality is rated lifting capacity, and the quality of the lifting materials is allowed to be effectively lifted.

A 50-ton crane means that it can lift up to 50 tons, that is, it can lift 50 tons without the boom extending.

The weight of crane lifting is related to the following aspects:

1. The length of the boom telescopic, the longer the boom is extended, the smaller the lifting capacity;

2. Luffing, the larger the angle of luffing, that is to say, the higher the lifting height of the boom, the larger the lifting capacity;

3. The angle of lifting, the larger the angle, the greater the lifting capacity.

The crane structure mainly includes:Lifting mechanism, running mechanism, luffing mechanism, slewing mechanism and metal structure, etc. The hoisting mechanism is the basic working mechanism of the crane, which is mostly composed of a hanging system and a winch, and there are also heavy objects that are lifted through the hydraulic system. The running mechanism is used to move heavy objects horizontally or adjust the working position of the crane, which is generally composed of an electric motor, a reducer, a brake and a wheel.

The luffing mechanism is only equipped on the boom type crane, and the amplitude decreases when the boom is raised, and the amplitude increases when it is lowered down, and it is divided into two kinds of balanced luffing and unbalanced luffing. The slewing mechanism is used to make the boom rotate, and is composed of a driving device and a slewing support device.

It depends on the position of the crane station, as well as the height of the object to be lifted.

How is it possible to arrange to lift something more than 50 tons with a 50-ton crane? Unless you don't think about safety. The case of not leaving the arm is 50 tons, and the lifting capacity of each arm will be reduced by one grade.

Cranes of different manufacturers have different configurations and different performance, so you can refer to the lifting performance table.

In general, it can be lifted from 0 to 50 tons; Special cases can also be lifted up to 55 tons.

Didn't get to the point, what was asked was the self-weight of the crane when it was empty?

50 ton crane ten meters crane 20 tons line.

Fifty tons of crane, radius forty-two meters, how much to lift.

Look at the distance of the maximum lifting base dismantling volume of 3 meters away can be lifted 25t. Then decrease 5 meters 19t 10 meters 7t 15 meters 20 meters 2t, the specific situation depends on the on-site working environment.

The crane is equipped with a lifting weight indicator (angle disk, also called weight limiter) installed at the root of the boom close to the angle indication of the driving position, it changes with the elevation angle of the boom, reflects the angle of the boom to the ground, knows the elevation angle of the different positions of the boom, according to the performance table and performance curve of the crane, you can know the amplitude value at a certain elevation angle, the lifting weight knows the hunger, the lifting height and other reference values.

Rice.

The lifting speed of 5 tons is 70m min, the large lifting height is 21-25 meters, the rotation speed of carrying luggage is 5 tons, and the driving speed is 60km h. The dimensions are long meters x width meters and high meters (can be 1 meter back).

Crane is a common name for crane, and crane is a lifting machinery.

It is a kind of machinery that does cyclic and intermittent movement. A working cycle includes arguing: the fetching device lifts the item from the fetch place, then moves horizontally to the designated place to lower the item, and then carries out a reverse motion to return the fetching device to its original position so that the next cycle can be carried out.

The 50-ton crane crane crane is 15 tons, and the farthest can lift Sun Wang 10 meters away. Because of the truck crane.

The theoretical tonnage is multiplied by 3, and then divided by the weight to be hoisted to obtain the longest distance, so the calculation formula for the 50-ton crane crane 15 tons can be lifted 10 meters to the stool is as follows: 50 times 3 is equal to 150, 150 divided by Zao Kai Chong 15 is equal to 10 meters, so 10 meters is the farthest distance when the 50-ton crane crane is 15 tons.
