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:

The turning of the bucket and the lifting and lowering of the boom are hydraulically operated.
