Working Condition Of Self Loading Concrete Mixer(II)

 Before Self Loading Concrete Mixer working, you should first check whether there is water in the stirring tank, and if so, it should be eliminated.

Start the engine, the two gear levers on the left side of the steering wheel in the "neutral" position.The right high and low speed conversion gear lever is dialed to the "low speed" position (heavy duty driving).

In the case of engine idling, confirm whether the "inlet and outlet" gear rod is in the "feed" position, and whether the "falling and rising tank" gear rod is in the "falling tank" position.

Push the gear lever on the left side of the steering wheel to "low speed" and "forward", loosen the brakes, step on the accelerator at the same time, push the handle (falling arm) forward, after filling the material, pull the handle backwards (lifting arm), after the upper hopper is lifted into place, pull the "open and close bucket" gear rod to the "open bucket" position, open the upper hopper barn door, you can realize the feeding process, after the loading end, the "open, close the bucket" gear rod is pulled to the "off bucket" position, and close the upper hopper barn door in time.

✔️Add Cement

The cement is poured into the cement tank and then loaded into the mixing tank. Pay attention not to backward the bucket when rising, it should be parallel to rise not easy to sprinkle cement, when adding the cement into tank, the feeding gate can be opened by half.

✔️Adding water into tank

Self-loading mixer truck (inside water) can be divided into automatic water and manual water addition two states, if you choose to use the automatic water addition function, please first set the water time, after the setting is completed, the switch can be rotated to the automatic position. In the manual water-added state, there is no need to set the time, as long as the switch is on, the system continues to maintain the water-added state until it is turned off.

From the outside of the loading mixer to add water, you need to connect the 220v or 380v power supply to connect the pump and the controller, set the time to remotely control the water.

✔️Adding water to water tank

First of all, Adding water to the pump directly, after the inlet pipe is full, then connect the water inlet pipe, start the car to use the hydraulic motor to drive the pump to absorb water to the water tank, the water tank exhaust hole to spray water outward to prove that the tank has been filled. Note: After the inside water tank is added, be sure to close the external suction pump switch in time, otherwise it will affect the working state of the self-loading mixer truck.

✔️Discharging Process

When unloading from the loading mixer, the "inlet and outlet" gear rod must be dialed from the "feed" position to the "neutral" position for a slight stop  , you can pull to the "discharge" position, and then "drop, rise" gear lever to the "liter tank" position, raise the mixing tank can realize the discharge process. according to the needs of the construction environment, the tank of the mixing tank can be rotated left and right to discharge, the specific operation Please click on the automation page in the lower right corner of the LCD screen to operate according to the needs. After unloading, please promptly dial the "falling, rising tank" gear lever to the "falling tank" position. the "inlet, discharged" gear lever is dialed to the "feed" position according to the operation requirements.

✔️Cleaning Process

In order to keep the self-loading mixer truck in good working condition and extend its service life. It is recommended that at the end of each day's work, the mixing tank, the outlet, the discharge trough and the surface of the vehicle be cleaned in time, especially the part with direct contact with the concrete, to prevent the residual concrete from solidifying and agglomerating.

How Are Mini Excavators Used in Landscaping?

Land Leveling

The Mini Excavator can transport large amounts of dirt from tight spaces. The front of the machine is also equipped with a shovel for easy site leveling. Cutting, grading and filling can be done with one machine, meeting all your needs for projects such as road development and maintenance or lawn landscaping.

Planting

You can use a mini excavator to grow plants. You can use the excavator to dig deep pits and even plant trees within them. The excavator's long arm allows you to get into tight or restricted spaces. This machine and its various attachments can help you plant trees and other vegetation on slopes, tight spaces and other tricky terrain.

Digging

Specialized attachments are available for digging holes and trenches. Micro excavators are ideal for such applications, and depending on the model you choose, you can accomplish digging at a variety of depths. This versatility helps with building swimming pools or ponds, digging utility trenches, and creating water features and garden landscapes. With the help of an auger or bucket attachment, you can easily dig up plant roots, install a hot tub or complete planting tasks.

Land Clearing

Land clearing is critical for many reasons. Clearing the land helps plants grow healthy and improves soil health. These factors alone create a beautiful landscape and increase property values over time. Additionally, clearing the land helps with project preparation and makes the construction site safer.

Grabbing

You can use a mini excavator to grab rocks, concrete, tree debris, and similar materials or objects and easily remove them from your project site. You can also use attachments to remove stumps, lift entire trees, and assist in cleanup efforts. Or, you can use some of the same attachments to create new landscaping.

In addition to landscaping, for other excavator application scenarios and solutions, you can contact Luyu. 

Differences Between Rough Terrain Forklifts And Ordinary Forklift

 When choosing a forklift, you should decide which type of forklift to use based on the specific work environment and needs. Rough terrain forklifts, while more expensive, have obvious advantages in situations that require frequent movement and dealing with complex terrain. However, ordinary forklifts may be more competitive in terms of cost and maintenance, especially in flat and stable work environments. It is advisable to conduct detailed field tests before purchase to ensure that the chosen forklift can meet the actual work requirements.

Differences Between Rough Terrain Forklifts and Ordinary Forklift

1. Driving mode and passability

Rough terrain forklift: four-wheel drive, equipped with large-diameter, wide-based off-road tires, ground clearance of more than 300mm, with excellent passability and off-road, suitable for use in complex terrain such as hills, mountains, beaches, sand, snow, ice and muddy roads.

Ordinary forklift: usually two-wheel drive, low chassis, small size, mainly used in flat and solid paved occasions, such as factories and enterprises.

2. Stability and operation movement

Rough terrain forklift: due to the high chassis, the center of gravity is also high, but the wheelbase and wheelbase are longer and wider, which enhances the stability in uneven places. In addition, it has multi-stage buffer system, such as tires, cab suspension, shock-absorbing seat and full-floating transmission system, which further reduces engine vibration and improves driving comfort.

Ordinary forklift: poor stability, mainly vertical movement, not suitable for side shift operation.

3. Engine power and applicable scenes

Rough terrain forklift: with high engine power, all-wheel drive and cross-country tires, it is able to drive under various complicated road conditions, especially suitable for use in the field, mine, construction site, mud, mudflat, mountain and sandy road.

Ordinary forklift: the engine power is relatively small, more suitable for use in flat and with solid road surface.

4. Reliability and Durability

Rough Terrain Forklift Trucks: Used in harsh environments such as the wild, they require higher durability and reliability, such as reinforced gantries, drive and steering axles, and fully enclosed wet brakes to ensure stability and safety under extreme conditions.

Ordinary Forklift Trucks: Although they perform well indoors or in flat environments, they may not be durable enough in harsh conditions.

SELF LOADING CONCRETE MIXER Maintenance

 During the operation, maintenance and overhaul of the self-loading mixer truck, please be sure to comply with the relevant safety regulations and carry out under the premise of personal and equipment safety.

Engine first maintenance: the engine worked for 300 hours, you need to replace the engine oil (15W-40 diesel engine oil 5-8kg), oil filter, diesel filter, air filter (Note: self-loading mixer truck air filter at least once a week to clean), after 1000 hours can be replaced.

Torque converter maintenance: The torque converter oil discharge port and filter in the lower left corner of the torque converter, use a wrench to unscrew the screws, drain the oil clean, and then clean the filter. After cleaning, open the cover plate and add No. 8 hydraulic transmission oil (about 20-25kg) from above the transmission, which is one-half of the glass tube after the engine is started.

Brake oil: Self-loading mixer truck regularly checks the brake oil, keeping the amount of brake oil not lower than the lower limit of the oil cup label. (The front brake oil cup is located above the front axle, which can be seen by opening the fixing cover screws, and the rear brake oil cup is located in the lower left corner of the driver's seat.)

Hydraulic System Maintenance: Replace the hydraulic oil (L-HM46 anti-wear hydraulic oil) once in 300 hours for the first time and clean the filter, using again for 1000 hours or once a year. The oil discharge port of the front hydraulic tank is at the bottom of the tank, and the amount of oil in the rear hydraulic tank is added to the red dot.

Before the first work of the new car, it is necessary to grease the hydraulic system pin shaft and articulation. The hydraulic system pins and articulations are filled or re-greased before working every day.

Bridges, reducers: Change the gear oil every 1000 hours. Add 4kg of gear oil to the middle of the bridge and 2kg of gear oil to each side.

Basic structure of loaders-Structural components of the loader

 The assembly process of a loader is a complex and delicate process, covering the assembly and commissioning of several core components and systems. To recognize the structure of the loader, first we need to have a preliminary understanding of the basic structure of the loader.

The working device of the loader is composed of bucket, movable arm, rocker arm and tipping bucket cylinder, movable arm cylinder and so on.

The whole working device is hinged on the frame. The bucket is articulated with the bucket cylinder through the connecting rod and rocker arm for loading and unloading materials. The movable arm is articulated with the frame and the movable arm cylinder to raise and lower the bucket.The following are examples of LUYU's loaders:
