liftstar Air scissor lift For large area and horizontal transport mainly occasions
for small footprint or high shelves, with vertical stacker or electric forklift handling mainly the occasion, single-sided and double-sided shelves series tray tray shelves can be selected.
If the load on the shelves of a library or stereo 1T, but no plank shelves, steel shelves with built recommend tray. Steel structure built of steel pallet shelf load effectively solve the greater electric stacker the greater the weight of the product, the old problem of the high cost, the more important is the use of a wall thickness of about 2mm square steel rigidity reaches the upper shelf are horizontal and vertical deflection ≤ 10mm stringent requirements, while reducing permanent deformation, and reduce costs.
For large area and horizontal Hand fixed lift table transport mainly occasions, if using manual hydraulic pallet trucks carrying the appropriate choice of single tray. For stacking the goods to the goods below at the bottom of the tray coincides with the end of the swastika sided tray or tray-type single well. If using a self-propelled motorized pallet trucks are suitable for handling not connected with the bottom of the foot of the nine-sided tray

For low viscosity hand pallet truck oil directly into a clean
The quality of hydraulic oil, directly affect the normal operation of the hydraulic cylinder truck, the following is a simple identification of impurities in the hydraulic oil Method:
1, sensory identification: a clear fluid metal particles in suspension, directly feel the presence of small particles when pinched with fingers twist; in the light, if reflective flash point, then the hydraulic components have been badly worn; If the hand pallet truck tank There are a lot of metal shavings bottom of precipitation, then the main pump or motor has been badly worn?
2, heating Identification: For low viscosity hydraulic oil directly into a clean, dry test tube heating tube heating Semi Electric Stackers oil if found to precipitate or suspended solids, then the oil already contains mechanical impurities???
3, the filter identification: For high viscosity hydraulic oil, diluted available pure gasoline, then clean filter paper retained if found a large number of mechanical impurities (metal powder) on filter paper, then the hydraulic components have been badly worn??
4, the sound identification: If the entire hydraulic system has a larger intermittent noise and vibration, while the main pump "buzzing" sound, even rod "crawling" phenomenon, then the hydraulic hand truck observed liquid fuel tank, fuel lines? export or transparent level gauge, you will find a lot of foam? This shows the hydraulic oil has been immersed in a lot of air?
5, the application Ferrography identification: Ferrography mechanical friction wear is Vice basic starting point, by means of iron spectrometer separates the hydraulic oil in the wear particles and other particles out and made of iron spectrum slices, then placed observed under a microscope or scanning electron microscope.

hand pallet truck loading height shall not obstruct the driver's line of sight
1, manual forklift fork carrier when the goods shall be required to adjust the distance between the two forks so electric pallet jack that both forks load balancing not skewed, the goods shall be affixed by the backrest side, the weight of the fork carrier shall comply with the load center of the curve signs regulations.
2, loading height shall not obstruct the driver's line of sight.
3, during the process of loading and unloading cargo, you must use the brake forklift.
4, when the fork close to or withdrawal of the goods, the speed should be slow and steady, do not pay attention to the wheels rolling cargo, wood pad, to avoid being compacted matter overfly wounding.
5, with the goods when the goods cross on to take the fork should be as deep as possible into the fork load manual Platform Stackers following, but also pay attention to the fork or sharp objects can not be met other goods. After the minimum should be used to stabilize the mast tilting loads to avoid load sliding backwards. When lowering the load, make a small mast forward, in order to load and extract the fork placed.
6, prohibited goods and fork to take the high-speed collision with a fork head with a hard object.
7, forklift operation, prohibited personnel standing on the forks.
8, when the forklift fork to take the goods, prohibited personnel standing around the fork to avoid collapse of the goods wounding.
9, prohibit the use of fork lift personnel engaged in high places, in order to avoid falling from height accident.
10, are not allowed at the pier on the shores of the goods shipped directly to the fork.
11, prohibit the use of single fork operation.

Stacker drive wheel drive motor speed significantly reduced or severe overload Cause
The battery voltage is too low or too big pile head contact resistance; between the motor commutator segments coke cause a short circuit between the chip; motor improperly adjusted brakes with brake leaving the motor running; drive head gear boxes and bearings lack of lubrication or chassis card motor armature short circuit; resistance.
Solution: Check the battery terminal voltage Stacker load or cleaning trailer coupling; clean up the commutator; adjust the brake clearance; checking cleaning and re-filling oil, remove Electric Hand Pallet Jacks jamming phenomenon; replace the new motor.Stacker crane lifting weakness or not
Reason: Gear pumps and pump mention excessive wear; improper high-pressure relief valve inside; oil pipeline spill; hydraulic oil temperature over; mast carriage
jamming phenomenon exists; pump motor speed is too low.
Solution: Replace worn or gear pump; readjust; inspection and repair; replace defective hydraulic oil and drum trucks the oil temperature rise causes; Check and adjust; Check the motor and troubleshooting.
piled high door frame automatically tilt difficulties or action not smooth
Cause: The tilt cylinder wall and seals for excessive wear; within the valve stem spring failure; piston rod stuck in the cylinder wall or bent; within the tilt cylinder seals fouling too much or too compressed.
Solution: Replace the O-rings or cylinders; replace qualified spring; replace damaged parts; cleaning adjustments.

lectric hand pallet truck battery daily maintenance points
1, the battery should always restocking distilled water ( pure water ) .
2 , long-term use of electric forklifts fully charged battery should be shelved . Frequency and kept apart by about 1 to 2 months for charging .
3 , in the multi-shift operation , the motor -driven warehouse forklift need a spare battery ( the case of continuous operation , fast battery power consumption , wear and tear on the battery is relatively large ) .
4 , when the battery charge , the scissor pallet truck charge must be completely out of the loop with the chopper , because in addition to the impact charger charging , the charger will damage arising from over-voltage chopper .
5, the battery should not be placed horizontally . Since the internal battery is generally 22 to 28% sulfuric acid . When the batteries are placed and the electrolyte plates can be overwhelmed pallet jack if a little space is left horizontally , then the battery will be part of the electrode plate exposed to the air , which is very detrimental to the battery plates , the battery and the general observation hole or top of the battery has vent with the outside world , so it is easy flowing electrolyte battery horizontally .
6 , choose smart phased charger to prevent overcharging leads to dehydration.
7 , choose a high efficiency electric wheel hub system to reduce the operating current.
8 , Qin charge or maintain a reasonable charging frequency , it is best to do a planned charging. If one day or two days for a full charge .
9 , to prevent the loss of electricity storage, loss of electricity stored in the battery of the most harmful
