Crane Truck
Crane refers to a machine that uses a hook or other object-taking device to hang heavy objects and perform cyclic operations such as lifting and moving in space. There are many types of cranes. Common names such as "crane", "tower crane", "overhead crane" and "truss crane" refer to one or several types of cranes. An automobile crane is a kind of crane installed on an ordinary automobile chassis or a special automobile chassis. Its driving cab and lifting control room are separately set. The advantages of this crane are good mobility and rapid transfer. The lifting mechanism is the basic working mechanism of the crane. Most of them are composed of a hanging system and a winch. There are also hydraulic systems that lift heavy objects. The luffing mechanism is only equipped on boom-type cranes. The amplitude decreases when the boom is raised and increases when it is bent down. It is divided into balanced luffing and unbalanced luffing. The slewing mechanism is used to rotate the boom. It is composed of a drive device and a slewing support structure. The chassis performance of the automobile crane is equivalent to that of a truck with the same total vehicle weight.It meets the technical requirements of road vehicles and can therefore pass unimpeded on various types of roads.
This type of crane is generally equipped with two operating rooms for getting on and off the vehicle, and the outriggers must be extended to maintain stability during operation. The range of lifting weight is very large, ranging from 8 tons to 1,600 tons, and the number of axles on the chassis can range from 2 to 10. It is the type of crane with the largest output and the most widely used. The metal structure is the skeleton of the crane. The main load-bearing parts such as the bridge, boom, and gantry can be box-shaped structures truss structures, or web structures, and some can use steel sections as support beams.
Truck cranes use the principle of hydraulic transmission to achieve various mechanical actions. We often use the power of the car to drive the hydraulic oil pump through the power take-off and connect the hydraulic valve to work. If there is no car power, we use the oil pump motor group to provide the power source. The oil pump motor group drives the motor to work through 380V voltage in the field, docks, ships, workshops, and other conditions without car power. If it is a field operation, it is also necessary to generate electricity from the generator and drive the oil pump through the motor.
Truck cranes are composed of booms, columns, frames, legs, and hydraulic components. The boom is the main device for lifting goods during lifting. The column is an important component connecting the boom and the frame. The goods mainly rely on the column when rotating left and right. The frame is mainly a component that connects and fixes the column and the legs. The main function of the legs is to keep the crane balanced during operation. The hydraulic system is composed of a fuel tank, a fuel pump, a fuel cylinder, a multi-way reversing valve, a hydraulic lock, a balancing valve, a motor, a slewing center joint, and pipelines. There are also winches, slewing mechanisms, etc.
Working Principle Of Truck Crane
Through the manipulation of the control system, the drive device converts the power energy input into mechanical energy, transmits the force and movement speed to the pick-up device, and the pick-up device connects the transported material with the crane, and completes the material handling task through the movement of the working mechanism alone or in combination. The movable metal structure connects the various components into a whole and carries the crane's own weight and lifting weight. The drive device is a power device used to drive the working mechanism.

Power Device
Automobile cranes usually choose diesel engines as their power source. From the perspective of economy and power, diesel engines are more suitable for the needs of large automobiles and construction machinery and can meet the vehicle-mounted and maneuverable requirements of automobile cranes. Different types of diesel engines have different specific structural principles, but the basic structure required to complete the engine working cycle is similar. Vehicle-mounted diesel engines usually consist of two major mechanisms: a crank-connecting rod mechanism and valve mechanism, as well as four major systems: oil supply system, lubrication system, cooling system, and starting system.
Basics
Automobile crane chassis mainly include general automobile chassis, special automobile chassis, and special tire chassis. It is the installation foundation and connection skeleton of all parts and equipment on the crane, the load-bearing and force-bearing carrier of the crane, and a combination of specific actuators for the crane to complete driving operations such as driving, steering, braking, acceleration, and deceleration. It is generally composed of four parts: transmission system, drive system, steering system and braking system. The chassis not only supports the weight of the whole machine but also transmits the power of the machine to ensure the operation and precise control of the machine.
Working Device
The working device of a truck crane is mainly composed of a lifting mechanism, a slewing mechanism, a luffing mechanism and a hydraulic system. Some cranes also have special working devices for completing certain process operations, such as clamps. The working device of a crane is mainly used for directly clamping, lifting, carrying, or loading and unloading heavy objects.
Lifting Mechanism
The lifting mechanism is the most basic working mechanism of a truck crane, which is used to achieve the vertical movement of the hoisted load. Most truck cranes use a hydraulic lifting mechanism, which is controlled by a hydraulic system, driven by a fixed or variable hydraulic motor, and coordinated actions of a reducer, clutch, brake, drum, wire rope pulley block, and hook. , some of which are achieved through a suspension system and a hoist. The hanging system is generally composed of a wire rope, a pulley block, and a sling, and the hook is the most common sling. Some truck cranes are also equipped with an auxiliary lifting mechanism to lift lighter objects or perform auxiliary operations.
Lifting Components
The lifting mechanism of a truck crane consists of a drive device, a transmission device, a winding device, a pick-up device, and safety devices such as brakes. Different types of truck cranes need to be equipped with different grabbing devices, and their drive devices are also different, but the layout is basically the same.
