The characteristics of truck cranes are ().

A truck crane is a crane that installs a crane structure on a general-purpose or special-purpose car chassis. It has the driving performance of a car., with strong mobility, high driving speed, and can be quickly transferred. It is a general-purpose crane with a wide range of uses and strong applicability, which is especially suitable for highly fluidity and non-fixed operating places.

Therefore, compared with the other two, the crane has greater mobility, and its walking speed is faster, which can reach 60km/h without damaging the road surface. However, the lifting operation cannot be carried out within the 360 range. The lifting area is restricted, and the requirements for the foundation are also higher.

The characteristics of automobile cranes are that they have the performance of automobile driving, strong mobility, fast driving speed, rapid transfer, and little damage to the road surface. The disadvantage is that legs must be installed during hoisting, cannot be carried, and it is not suitable for working on soft or muddy ground.

Automotive crane is a self-propelled full-turn crane that installs the crane on the chassis of an ordinary heavy-duty vehicle or a special-purpose vehicle.

What are the models of truck cranes?

Thousands of models of car cranes from 1t-1200t. Generally, the number in the name of the car crane is the tonnage. For example, qy50k-1 is the k series 50t truck crane.

x0dx0a car crane, also known as car crane, can be used on the road or in engineering. X0dx0a also has tire cranes, which are generally used in horse heads or warehouses.

It is divided into: frog-shaped legs, x-shaped legs, and h-shaped legs according to the type of legs.

Small-tonnage cranes mainly include 8 tons, 16 tons, 25 tons, 50 tons, 70 tons and 100 tons. There are 160 tons, 220 tons, 300 tons, 400 tons, 500 tons, 800 tons, 1000 tons, 1200 tons and 1600 tons.

Prohibited operations in the operation of automobile cranes are

Do not hoist when encountering buried objects with unclear tensile force. The work site is so dark that it is impossible to see the site clearly, the objects being suspended and the command signal are not suspended.Do not hang when there is no padded between the corner of the hanging object and the tied steel rope. Don't hang heavy objects crookedly. The items in the container should not be hung when they are full.

The position of the suspended object is not directly below the crane, and it is forbidden to pull the object diagonally. When the suspended object is large and higher, the upper end of the object should be suspended. If the hanging object is long, it is best to set up two hanging points to rise and fall at the same time, so as to avoid the unbalanced slippage of the center of gravity of the object or other effects.

(1) Oblique suspension or not. ( 2) Don't hang overload. ( 3) The bulk items are too full or tied up and cannot be hung firmly. ( 4) Do not hang the edge of the hanging object without protective measures. ( 5) Don't hang people standing on the hanging object. ( 6) The command signal is unclear. ( 7) Do not hang the components buried in the ground. ( 8) If the safety device fails, it will not be suspended.

Objects buried in the ground are not allowed to be suspended; safety devices are not allowed to be suspended if they fail or are sick;The light at the scene is dark and the starting and landing point of the hanging object is not allowed to be seen; the edge of the edge object is not allowed to be in direct contact with the steel wire rope without protective measures; it is not allowed to be suspended in strong winds above level six.

What are the functions of tower cranes and truck cranes

Tower crane is a kind of crane used to transport various materials to high floors during construction. The lifting weight is usually not large. The biggest feature of the truck crane is that it can run through the road to the place where it needs to be used, that is, it has strong mobility.

The function of the tower crane: it is used to hoist the raw materials for construction such as rebar, corrugated steel, concrete and steel pipe for construction. Tower crane is the most commonly used lifting equipment on construction sites, also known as "tower crane", which is an indispensable equipment on construction sites.

Crane is a kind of mobile crane, which is usually composed of chassis, crane structure, legs and cab, etc. The main function of the crane is to load, unload and handle goods on the construction site or site. Therefore, cranes are also known as mobile cranes.

The function of the tower crane: The main function of the tower is to hoist materials, which can be horizontal transshipment or vertical transportation. The materials of its crane include rebar, corrugated, concrete, steel pipe, etc. Introduction to tower crane: Tower crane is the most commonly used lifting equipment on construction sites, also known as "tower crane".

Frame The frame is mainly composed of a bridge frame, a small car frame, a control room and an escalator, which constitute the main body of the crane. Mechanism For overhead cranes, there are only two mechanisms, one is the lifting mechanism and the other is the operating mechanism.There is no steering mechanism and inflation mechanism. Truck cranes have the above four mechanisms.

hang and so on. Fixed type: dock crane, tower crane, gantry crane, etc. The name crane is a unified title. Cranes usually refer to automobile cranes, crawler cranes and tire cranes. It is widely used in lifting and handling machinery in ports, workshops, construction sites and other places. Cranes are used in lifting equipment, rescue, lifting, machinery and rescue.
