Warehouse Safety
Bao Chanh offices offer a Racking Maintenance and Safety Program to ensure the racking systems are operated within the orginal design specification, and to physically check the systems for any damage caused by Mechanical Handling Equipment.
Damage Pallets

The quality, design and materrial of a pallet is a critical factor in the design
of pallet racking systems. Some pallets, in particcular the plastic variety, are
excellent for block stacking, with out the use of additional steel supports
Use of the wrong type of pallet, or damaged pallets can lead to rack collapse Bao Chanh guide lines, advise optimum frame dimensions for alternative types of pallet. Pleased to offer advise anh testing procedures for different styles of pallet .Please contact your BAO CHANH office ,who will be pleased to offer advise and testing procedures for different styles of pallet
Loading & Unloading
- Use the right forklift.
- The forklift must have the adequate capacity and be capable of lifting loads to the required height
- Correct Fork length
- Correct fork length is critical to ensure load stability and minimize rack damage
- Forks must be of sufficient length to support all pallet boads
- Forks must not extend beyond the pallet boards
- Picking up Pallet
- All pallets must be picked up square to the forks
- If pallets are not pickerd up squarely the effetive size of the pallet is increased
- DO NOT nudge a pallet to square it up on the forks.


Approach
- Entering The Rack
- To safely deposit or retrieve a pallet the Forklift MUST approach the racking squarely and not an angle
- DO NOT attempt to deposit or retrieve a pallet when the forklift is not aligned correctly
- DO NOT nudge a pallet to position it correctly in the rack
- Load Placement
- Incorrect placement of loads can be dangerous
- Loads should be evenly distributed across the beam length
- Pallets should be positioned correctly
- Pallet weight should not exceed design load
- Loads should be positioned evenly across the pallet


Damage points
- Beam Deflection
- The maximum beam deflection in a loaded
- Condition = SPAN / 200
- Example 2700 / 200 = 13.5 mm

- Upright Damage
- The maximum Upright Damage due to impact in the direction of the bracing (Front to Back) over a 1000mm distance = 3.0mm
- If the damage is localised, the allowable damage for a distance less than 1000mm in length is pro-rata the above. Eg 1.5mm over 500mm, 2.25mm over 750mm
- Where possible always test over 1000mm span
 
- Upright Damage
- The maximum Upright due to impact in the direction of the beams (Side to Side) over a 1000mm distance = 5.0mm
- If the damage is localised, the allowed damage for a distance less than 1000mm in length is pro-rata the above. Eg 2.5mm over 500mm, 3.75mm over 750mm
- Where possible always test over 1000mm span
- Bracking Damage
- The maximum Bracing Damage in either direction of plane over a 1000mm distance = 10.0mm
- The allowable damage for bracing less than 1000mm in length is pro-rata the above. Eg 5.0mm over 500mm, 7.5mm over 750mm.

- Out of Plumb
- The maximum Out of Plumb due to impact or damage in either direction or plane is measurement length / 350
- When measuring Out of Plumb, racks must be in an unloaded condition
- This is for a manually operated equipment environment as tolerances are greater for guided or automatic equipment.
