motive crane lifting time

(13) during lifting operation of truck crane, there must be no people in the cab of the car, heavy objects must not exceed the top of the cab, and no lifting in front of the car.

Car cranes are not allowed to drive heavily or lift weight without a leg. When the tire crane does not work with legs, the tire pressure should be about 0.7MPa. The lifting weight should be within the rated weight range of the specified leg.

Newly installed, overhauled or changed important performance of cranes must be carried out load tests in accordance with the relevant provisions of crane performance tests before use. After passing the test and completing the relevant procedures and safety permits, it can only be put into use.

The working level of the crane is to consider the degree of utilization of weight and time and the working characteristics of the number of working cycles. It is divided according to the utilization level of the crane (the total number of work cycles during the entire design life) and the load state.

What are the classifications of truck cranes?

1. According to the type of legs: frog legs, x-shaped legs, and h-shaped legs.

2. Most of them are classified according to the lifting weight: light truck cranes (lifting weight less than 5 tons), medium truck cranes (lifting weight 5-15 tons),Heavy truck cranes (lifting weight 5-50 tons), super heavy truck cranes (lifting weight more than 50 tons). Due to the requirements of use, its improvement ability tends to increase.

3. There are 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.

4. Tire crane Tire crane is a moving arm rotary crane that uses a tire chassis to walk. Tire crane is a kind of all-turn crane whose crane structure is installed on a special chassis composed of heavy tires and wheel axles. Its superstructure is basically the same as that of a crawler crane. Car crane is also a kind of tire crane.

What are the types of truck cranes?

According to the type of leg: frog leg, x-shaped leg, h-shaped leg.

What are the types of cranes: introduction of types. There are many kinds of cranes, and the classification skills are also different.

There are many kinds of truck cranes, and the classification methods are also different. Generally, it is classified according to the lifting weight: light truck cranes (lifting weight of less than 5 tons), medium truck cranes (lifting weight 5-15 tons), heavy truck cranes (lifting weight 5-50 tons) and super heavy truck cranes (lifting weight of more than 50 tons).

Type of cantilever beam: the frog leg span is narrow, which is only suitable for small-tonnage cranes. X-legs are easy to slip and rarely used. The H leg can achieve a larger span, which has obvious advantages for the stability of the whole machine.Therefore, most of the hydraulic truck cranes produced in China adopt H-shaped legs.

What does a truck crane mean?

Among many types of cranes, truck cranes, also known as truck cranes, are a kind of mobile crane. It is suitable for the hoisting of large and medium-sized equipment and components with large single weight. The operation cycle is short, it has a wide range of applications, good mobility, and can conveniently transfer the site, and the road or site It has the characteristics of high demand and high platform fee.

What are the types of cranes: Introduction: A truck crane is a crane installed on an ordinary car chassis or a special car chassis, and its cab is set separately from the lift control room. This kind of crane has the advantages of good mobility and fast transfer.

SteamA truck crane is a crane installed on an ordinary car chassis or a special car chassis. Its cab and the lift control cab are set separately. The advantages of this crane are good mobility and fast transfer. The disadvantage is that you must support your legs when working, and you can't drive with weight. It may not be suitable for working on soft or muddy ground.

Tropic crane is a kind of widely used engineering machinery. This kind of machinery can walk at a relatively high speed, good mobility, strong adaptability, self-repared power does not need to be equipped with power supply, can operate in the field, and is simple and flexible. Therefore, in transportation, urban construction, fire protection, large material yards, infrastructure, first aid, etc. The field has been widely used.

The frog leg span is relatively narrow, which is only suitable for smaller-tonnage cranes; x-type legs are prone to slippage and are rarely used;H-type legs can achieve a large span, which has obvious advantages in the stability of the whole machine. Therefore, hydraulic truck cranes produced in China mostly use h-type legs.

What is the purpose of the truck crane?

It can be used for high-altitude lifting objects, lifting equipment, installation, and accident vehicles, etc. Purpose: 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.

Generally, truck cranes are used in construction sites, trees, poles, viaducts, warehouses and other fields, and have a wide range of uses. The power of truck cranes comes from the engine, and diesel engines are generally used.

Uses of cranes: lifting equipment, rescue, lifting, rescue, handling moving objects.Cranes include fixed tower cranes, mobile car cranes, semi-mobile gantry cranes, crawler cranes, ship cranes and other types. Cranes are good helpers in construction work.

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. The overhead crane has two mechanisms: lifting and running. The cart is equipped with a large lift and a small lift, which is used to lift heavy objects.

It is used for lifting and handling machinery in ports, workshops, construction sites and other places. Cranes are used for lifting equipment, rescue, lifting, machinery and rescue. Multi-action cranes for vertical lifting and horizontal handling of heavy objects within a certain range. Crane is the common name of crane.

What are the characteristics of truck cranes?

Motory cranes usually have the following characteristics: Flexibility: Motory cranes can be used anywhere and can be easily moved on the move. Convenient transportation: the truck crane is light and easy to move, which is convenient for transportation. Versatility: Truck cranes can complete a variety of tasks such as hoisting and handling.

When hoisting, support the crane on the ground with the legs. 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 main advantages of truck cranes are fast driving speed, fast movement, and little damage to the road surface. It is suitable for operations with high mobility and frequent change of locations.This kind of crane cannot be loaded and has poor stability during the installation of components. Due to the length of the fuselage, the turning radius is large when driving.

Because the truck crane has the characteristics of strong mobility, large lifting capacity and easy operation, it can complete a large number of construction operations in a relatively short time and improve work efficiency. Port field: In the port field, truck cranes are often used for loading and unloading goods, storage yard operations, etc.

Tropic crane is a kind of widely used engineering machinery. This kind of machinery can walk at a relatively high speed, good mobility, strong adaptability, self-repared power does not need to be equipped with power supply, can operate in the field, and is simple and flexible. Therefore, in transportation, urban construction, fire protection, large material yards, infrastructure, first aid, etc. The field has been widely used.
