Pre-work inspection
Pre-work inspection work, for your forklift operation safety has a vital role, is not to be ignored a work.
1, before checking your forklift, please perform the following actions:
a, first of all, park the forklift in a safe and stable place
b, stop the engine, pull up the hand brake, and set all the control levers in the neutral position.
c. Make the mast vertical to the horizontal line, lower the forks and let the forks contact with the ground.
2. Carry out inspection work in the following areas:
Review along the perimeter of the forklift for oil or water leaks.
Review whether the tire pressure is normal, whether the tread is cut, whether the steel rim is deformed, damaged, and whether the screws are locked. Check whether the rear support frame and fork have deformation, cracks, fork positioning Xiao is normal. Check whether the mast chain tightness is consistent. Check whether the light system is broken, whether the roof canopy is deformed and cracked.
Open the engine cover and check the cooling water level. Check engine oil level. Check the fan belt for cracks and wear. Check battery electrolyte level. Check hydraulic fluid level. Check brake fluid level. Lower the hood, get in the car, and sit in the seat. Adjust seat to proper position. Steering wheel tilt angle adjusted to optimum position. Check if the horn function is normal. Test the brake pedal to make sure it is functioning properly. Test the accelerator pedal to make sure it is functioning properly. Test the clutch pedal to see if it is normal. (Manual shift model) Try to step on the inching pedal to see if it is normal. (For automatic transmission models) Operate the hand brake lever to make sure it is working properly.
Turn the key switch to ON and check if the fuel level is sufficient. Check whether the warning lights and gauges on the instrument panel function normally. Check that the steering light lever functions properly. Check that the brake lights function properly. Start the engine and let it warm up for 5 minutes to check if there is any strange sound or abnormal vibration. Check whether the mast lifting and tilting is smooth and whether there is oil leakage from the hydraulic cylinder and oil pipe. Move the forklift slowly to a safe area. Check whether the clutch function (inching switch function) is normal. Check whether the braking force is sufficient. Check whether the steering wheel steering is normal.
From the above, it can be seen that its checking work to dozens of items, is a tedious thing, but the most important thing is safety, stacker trucks once an accident, the impact and damage are very large. In order to maximize safety and minimize the danger, it is still hoped that the operator can pay more attention to these aspects of the problem.
Stacker purchase method editor
(1) according to the operational function of the choice of electric stacker truck
The basic operational function of the stacker truck is divided into horizontal handling, stacking? /pickup, loading/unloading, picking. According to the operational functions to be achieved by the enterprise can be initially determined from the company's from the company's product line. In addition, special operational functions will affect the specific configuration of the stacker truck, such as handling is paper rolls, iron, etc., the need for stacker trucks to install the genus to complete the special functions.
(2) according to the operational requirements of the choice of forklift truck
stacker operational requirements, including pallets or cargo specifications, lifting height, operating channel width, climbing degree and other general requirements, but also need to consider the operational habits (such as accustomed to driving or standing), operational efficiency (different models of different efficiencies), and other aspects of the requirements.
(3) operating environment
If the enterprise needs to handle the goods or warehouse environment on the noise or exhaust emissions and other environmental protection requirements, in the selection of models and configurations should be taken into account. If it is in a cold storage or in an environment with explosion-proof requirements, the configuration of the forklift should also be cold storage type or explosion-proof type. Carefully examine the forklift operation needs to pass through the location, envision possible problems, for example, in and out of the warehouse when the door height of the stacker truck has no effect; in and out of the elevator, elevator height and load on the impact of the stacker truck; in the upper floor when the operation, the floor load whether to meet the appropriate requirements, and so on.
Note: When selecting and determining the configuration, we should describe the working conditions in detail to the supplier of the forklift trucks and conduct field surveys to ensure that the forklift trucks purchased fully meet the needs of the enterprise. Even after completing the above steps in the analysis, there may still be several models at the same time can meet the above requirements. At this time need to pay attention to the following aspects:
①? Different models, different work efficiency, then the number of forklifts needed, the number of drivers are different, which will lead to a series of cost changes, see the performance evaluation part of this paper on the cost of the discussion.
②? If the stacker trucks operating in the warehouse, different models require different aisle widths, lifting capacity also varies, which will lead to changes in the warehouse layout, such as changes in the amount of goods stored.
③? Changes in car models and their number will have an impact on many aspects of fleet management.
④? Different models have different market retention, and their after-sales protection ability is also different, for example: low driving three-way stacker trucks and high driving three-way stacker trucks belong to the same series of narrow aisle forklift trucks, both can be in a very narrow aisle (1.5 to 2.0 meters) to complete the stacking/stacking, picking up goods. However, the cab of the former can not be lifted, thus the operation vision is poorer and the working efficiency is lower. Since the latter can completely cover the functions of the former and has a better performance, the market for the latter exceeds that of the former by a factor of 4 to 5 in Europe and by a factor of 6 in China. Therefore, most suppliers focus on the development of high-position driving three-way stacker trucks, while low-position driving three-way stacker forklifts are only used in small tonnage, low lifting height (generally within 6 meters) working conditions. When there are few sales in the market, its after-sales service will be relatively weak in terms of the number of engineers, experience of engineers, spare parts inventory level and other service capabilities.
To choose the most reasonable program after a comprehensive assessment of the impact of the above aspects.
