Do you know the composition and function of various parts of the truck-mounted crane that has been driven for so many years? Next, Hebei Shenghang Special Vehicle Manufacturing Co., Ltd. will briefly introduce the various components of the truck-mounted crane for you.
1.Boom
The boom is extended and retracted by a hydraulic cylinder, and the hook pulley is suspended from the top of the boom.
2.Load indicator
The load indicator indicates the total rated load of the vehicle chassis under no-load condition for various boom lengths and boom angles.
3.Hoisting mechanism
The hoisting mechanism is driven by a hydraulic motor and lifts or lowers the heavy objects through a wire rope.
4.Columns
The column supports the boom, the hoisting mechanism and the luffing cylinder, and is driven by the slewing system.
5.turn system
Swing system (hydraulic motor, make the column swing).
6.Racks
The rack mounts directly to the car chassis, supporting the uprights and outriggers.
7.Hydraulic tank
The hydraulic oil tank accommodates the hydraulic oil specially used for the truck-mounted crane, and plays the role of heat dissipation and sedimentation filtration.
8.Outrigger joystick
The outrigger lever is used to control the telescopic action of the left and right outrigger cylinders.
9.Outrigger cylinders
During the operation of the truck-mounted crane, in order to stabilize the vehicle, the outrigger cylinder is extended to the ground to improve the operational stability of the truck-mounted crane.
10.Speakers
When used for lifting operations, it alerts the personnel within the scope of operation.
11 Acceleration joystick (hand accelerator)
The accelerator joystick is used to adjust the speed and output of the engine to meet the hoisting needs.
12.Swivel joystick
The slewing joystick is used to control the slewing mechanism, so that the column and the boom can rotate left and right.
13.Luffing joystick
The luffing lever is used to control the telescopic action of the luffing cylinder to realize the height control of the boom.
14 Hoist joystick
The hoisting lever is used to control the hoisting mechanism (lifting or lowering the weight).
15.Elescopic joystick
The telescopic joystick is used to control the action of the telescopic oil cylinder, and the telescopic control of the boom is carried out through the telescopic pulley frame.
16.PTO rod (power take-off rod)
The PTO rod (power take-off rod) is used to control the power output and cutoff of the engine to the truck-mounted crane.
17 .Luffing cylinder
The luffing cylinder is the actuator that makes the boom tilt up or down.
18.Hook pulley block
Through the increase or decrease of the upper pulley, the conversion of the hoisting magnification can be realized, and the heavy objects can be directly hooked.
19.Wire rope
Transfer the output torque of the reel to the hook.
20.Over-roll alarm device
When the hook pulley is close to the top of the boom, the over-roll alarm device will automatically send out an alarm signal. This prevents overwinding of the wire rope.
21.Rear outriggers
It is installed at the rear of the rear axle of the vehicle and connected with the girder to further improve the stability of the vehicle.
