Modern warehousing logistics tends to mechanization and automation operations, higher and more compact yardage, extremely high efficiency of warehouse use, but the moment high-speed turnover scheduling and mechanized operations will inevitably appear shelves of collision and wear and tear.
Learn the knowledge of daily inspection of shelves, can effectively reduce the shelves in the use of the process of safety hazards, comprehensive assessment of shelves at the current stage of the quality defects, to avoid direct or indirect losses caused by safety incidents.
So what should we pay attention to in the daily use of shelves?
I. Distance level
1,Safety spacing between the goods and the bottom of the upper beams
In the palletized racking "WB/T1044-2012" standard, it is clearly stipulated that the safety spacing should meet the requirement of minimum 75mm to avoid damage to the goods and beams during handling.
2,Goods spacing
The standard requirement is that the minimum distance of 100mm should be met to avoid cargo collision and clear cargo positioning.
3,Maximum lifting height of forklift
It should be 200mm upward from the top height of the shelf to avoid dangerous operation of forklift.
Points for daily inspection: whether the goods are neatly arranged, whether they are ultra-wide and ultra-high or beyond the edge of the pallet, whether the goods are stacked high with obvious tilt, whether the position of the goods on the shelves is appropriate, whether the forklift truck access to the goods in accordance with the provisions of the operation and so on.

II. Shelf safety device level
In the service life of up to ten years and more shelves, focus on the shelves of the ancillary measures, is to maintain the safe use of shelves of a major guarantee.
1,Isolation net and back seal net
Isolation net: effectively isolate personnel and equipment, play a safe and anti-theft role.
Back-sealing net: effectively block the goods falling from the shelf, reduce the fall and the impact, avoid causing casualties.
Points for daily inspection: whether the bolts of isolation net and back seal net are loose and whether there are traces of impact.
Collision guardrail and guardrail
Anti-collision guardrail and guardrail can effectively maintain the distance between the access equipment and shelves, and effectively prevent the forklift trucks from causing structural damage to the shelves' columns and horizontal and diagonal braces during transportation.
The main points of daily inspection: whether the guardrail and guardrail are deformed by the impact, and whether the expansion bolts are loose.
3,Anti-collision foot guard
Foot guards are especially important for the protection of the column at the corner of the channel, the corner of the forklift's blind spot is a high-frequency collision area. Setting up anti-collision feet can effectively reduce the column due to impact caused by the overall tilt and the probability of collapse.
The main points of daily inspection: whether the anti-collision foot guard is deformed by the impact, whether the anchor bolt is loose, whether the ground is damaged.
4,Passageway safety net
Safety net is to prevent falling injuries of a labor protection appliances, shelf beams at the bottom of the tunnel if the passage, in principle, must be set up to prevent accidents caused by falling goods channel safety net.
The main points of daily inspection: check whether there is corrosion and damage to the safety net, and often clean up the debris on the net or falling goods.
5,Load warning signs and safety warning signs
Load warning signs: remind personnel of the normal load on the shelf structure, but also can warn the operator to pay attention to the safety of the shelf load. The use of warning signs can greatly reduce the collapse of shelves and the occurrence of accidents.
Safety warning signs: warn the operator of the vehicle, personnel attention to the danger, to remind personnel to take appropriate safety measures early, to indicate where the staff can work and remind the work must pay attention to other safety matters.
Points of daily inspection: check whether the data of the load warning sign is accurate, check whether the shelves change the structure or whether the load capacity of the shelves exceeds the maximum safe load.
Note: The configuration of the shelf safety device is preferred to be warning color.
III. Stressor level
1,Beam safety pin
Beam safety pins play an important role in the protection of assembled beam shelves, it can prevent forklift misoperation makes the goods top hit the upper beams caused by the beams fall off, the safety pins of the fall and damage will be for the shelves using enterprises to lay a hidden safety hazard.
The main points of daily inspection: check whether the safety pin is missing or falling off, check whether the safety pin is installed in place.
2.Ground Bolt
Ground bolts connect the columns with the ground for fastening, and enhance the pull-out resistance and torsion resistance of the racking system.
With the prolongation of the shelf use time, the loosening of the ground bolt is inevitable, and there are many reasons for its loosening, such as: installation fastening is not in place, the accidental collision of external forces, the structure of its own bearing frequency changes, changes in the use of the ground, and so on.
The main points of daily inspection: whether the tightening torque of the foot bolt is up to standard, whether the nut is loose or missing, whether the stud is skewed, whether the bolt is rusted and loosened.
IV. Other logistics equipment
Mainly for the damage inspection of pallets, in the daily storage process, the damaged pallets are used on the shelves, which may cause the pallets and goods to fall.
Taking wooden pallets as an example, if the following conditions occur, they should not continue to be used.
1. Lack of cross-legged support;
2, the tray panel is missing;
3, the nail head loose and protrude the tray panel;
4. Support leg damage;
5.The tray panel is damaged or cracked.
The main points of daily inspection: whether the selection of wooden pallet is correct, the bottom form is generally selected as a font tray, the deflection of the wooden pallet should not be greater than 1/100 or 15mm in the case of heavy load, whether the direction of the fork is correct, whether the pallet itself is broken or cracked.
V. Safety guidance recommendations
(1)Standardizing the use of shelves and grasping the details of daily inspection can effectively guarantee the safety of shelves, and it is recommended to establish three different levels of safety inspection and testing mechanism.
Immediate inspection: Once problems are found in daily use, they should be reported to the person in charge of safety immediately, and the person in charge of safety should take corresponding measures.
(2)Regular Inspection: The person in charge of safety should regularly organize the inspection and maintenance of the shelves, and any problems found should be recorded and appropriate measures should be taken. Regular maintenance, such as regular organization of forklift operators, warehouse personnel safety training, regular inspection of safety parts, regular tightening of bolts, regular rust removal, etc..
(3) Professional annual inspection: at least one professional inspection per year, completed by professional testing organizations.
