Dongfeng Xiaokang 3-square hook-arm garbage truck top loading configuration: high-strength alloy steel integrated main hook arm, reinforced auxiliary beam, cast steel tail roller, manual, electronically controlled dual control device, hydraulic loading, lowering and locking Tightening, self-unloading and other operations, to achieve the circulation of a car with multiple boxes.
The hook-arm garbage truck is also called a detachable garbage truck. It uses a full hydraulic control operating system. The garbage bin and the chassis can be completely separated. It has a reasonable structure, simple and stable operation. The advantages of high use efficiency, high sealing performance, and convenient dumping can realize the joint operation of one vehicle and multiple garbage bins, circular transportation, and fully improve the transportation capacity of the vehicle. Mainly applicable to municipal sanitation, property management, large-scale factories. Collect and carry various garbage in various places such as working conditions.
Hook arm garbage truck model features:
1. Strong maneuverability, one car is responsible for the transportation of multiple garbage bins at the same time, high efficiency and reduced transportation costs; 2. The garbage bin covers a small area, saves civil engineering resources, and does not require additional lifting settings; 3. Extra high High-strength wear-resistant steel with a yield strength of 490MPa; 4. The equipment has light weight and large lifting capacity, and the maximum dumping angle is 50 degrees; 5. The equipment is durable and has a long service life; 6. The safety system includes: loading and holding valves, hydraulic and Mechanical box locking device, tilt locking device, good tilt locking; 7. Equipped with hydraulic oil filter indicator; 8. Fast operation speed, one-time loading and unloading round-trip time is 80-120 seconds; 9. Advanced heavy box loading and unloading support mechanism , Hard and soft work are equally good. Before the hook-type garbage truck is loaded with garbage, it can only hang up the power take-off when the no-load operation reaches 6 standard air pressures --- at the lower left of the steering wheel in the cab, check for leaks or abnormalities of various parts, and then press the operation sign Indicate the location to operate.
Ultrasonic Drilling Rig For Geological Survey Investigation
Sonic drilling is a soil penetration technique that strongly reduces friction on the drill string and drill bit due to liquefaction, inertia effects and temporary reduction of porosity of the soil. The combination makes penetrating for a large range of soils easy for our Sonic rigs and tooling. The penetration rates in most bedrock are faster with this technology also.
At first glance, a SONIC drilling rig looks very much like a conventional air or mud rotary drill rig. The biggest difference is in the drill head, which is slightly larger than a standard rotary head. The head contains the mechanism necessary for rotary motion, as well as an oscillator, which causes a high frequency force to be superimposed on the drill string. The drill bit is physically vibrating up and down in addition to being pushed down and rotated. These three combined forces allow drilling -to proceed rapidly through most geological formations including most types of rock.
In overburden, the vibratory action causes the surrounding soil particles to fluidize, thereby allowing effortless penetration. In rock, the drill bit causes fractures at the rock face, creating rock dust and small rock particles, which facilitates advancement of the drill bit. In many instances the drilling and coring of rock and earth can be accomplished without the use of any drilling fluid whatsoever. This is an important requirement for environmental drilling projects. Compressed air, drill mud, or plain water can be utilized to remove the cuttings and speed up the operation further, depending on the application that the machine is used for.
The oscillator is driven by a hydraulic motor and uses out of balance weights to generate high sinusoidal forces that are transmitted to the drill bit. An air spring is also incorporated in order to confine the alternating forces to the drill string. The frequency can be varied to suit operation conditions and is generally between 50 and 160 hertz (cycles per second). As a comparison, ordinary household current in many countries alternates at 60 hertz. This frequency range falls within the lower range of sound vibrations that the human ear is capable of hearing.
While the principle behind the SONIC drill rig appears complicated, the machine is actually very simple to operate. The driller only adds vibratory energy to the normal rotary motion. He simply chooses a frequency that gives him the best drilling rate or best core recovery, as the case may be.
