electric pallet jack Stacker

1, Stacker wheels or drive motor speed significantly reduces severe overload cause: The battery voltage is too low or too big pile head contact resistance; between the motor electric platform stacker‍ commutator segments coke cause a short circuit between the pieces; motor brake motors with improperly adjusted leaving braking operation; drive head gearbox and bearing pedestal lack of lubrication or jamming; motor armature is shorted. Solution: Check the battery terminal voltage Stacker trailer coupling load or clean; clean up the commutator; adjust the brake clearance; check the cleaning and re-filling oil, remove jamming phenomenon; replacement motor.

2, Stacker crane lifting weak or can not reason: Gear pumps and pump mention excessive wear; improper high-pressure relief valve inside; oil pipeline spill; excessive oil temperature; mast carriage the existence of jamming; pump motor speed is too low. Solution: Replace worn or gear pump; readjust; check and repair; replacement of unqualified hydraulic oil and check the oil temperature of reasons; check and adjust; check the motor and troubleshooting.

3, electric stacker door frame Autotilt difficulties or action is not smooth reasons: tilt cylinder wall and seal excessive wear; valve spring failure within the stem; piston rod stuck in the cylinder wall or bending; tilt cylinders inside fouling too pressed too much or seals. Solution: Replace the O-rings or cylinder; replace qualified spring; replace damaged parts; cleaning adjustments.

4, less than the pump pressure or too slow. Cause: The Electric Hand Pallet Jacks‍ pump cover slot ring damage, excessive internal leakage; gear wear; pump motor speed is reduced; there is blockage in the pipe. Solution: Replace; replace oil pump; check commutator, remove inter-chip coke, carbon brushes position adjustment; check the cleaning.

5, electrical operation is not unusual reason: electrical box Micro Switch damaged or improperly position adjustment; the main electrical control circuit fuse or fuse; low battery voltage; contactor singeing, or dirt poor contact caused by too much ; contact no action. Solution: Replace the micro switch, re-adjust the position; replace the fuse of the same type; recharged; repair contacts, adjust or replace the contactor; check whether High Lifting stacker‍ the contactor coil circuit breaker or replace the contactor.

Cranes and cranes and other off-road tracks

Cranes and cranes and other off-road tracks, crane operations remain stable inside the body stretched High Lifting stacker beam is equipped. Frame beams, H shape and X-shaped, almost hydraulic work. In addition, truck cranes video jack reception equipment. Stowage shaped ー also equipped overhanging beams, horizontal sheets of manual and more. Frame beams, overhanging beams box beams overhanging beams, overhanging beams are composed of floating, etc., according to acting hydraulic action, stability and level of the body. Rail cranes, work area (front, side, rear) to raise the Hydraulic fixed lift table performance difference of the body greatly. Rail cranes, sequence rear, side, front and high stability. The total nominal performance front elevation areas, rear and side aspects of the field of load 21%? 54%, in order to become, to raise performance in front of the field, the same person behind the field and raise the jack to the front of the equipment.

Chinese Dragon of semi-electric stacker features

 1 Chinese Dragon of semi-electric stacker adopts new rear axle structure, the Stacker structure is more reasonable.

     2 Chinese Dragon of semi-electric stacker imported pneumatic spring-loaded handle device easier to use reasonable.

     3 Chinese Dragon of  Fixed lift table semi-electric stacker molding raw materials imported from Germany, the door frame, in terms of quality strictly.

     4 Chinese Dragon of semi-electric stacker using imported Italian pump, according to customer requirements can be made ??high-quality replacement pump.

     5 Chinese Dragon of High Lifting stacker semi-electric  stacker with a push pull lighter, more lightweight and flexible, easier to use, etc.

     6 Chinese Dragon of semi-electric stacker in scientific, safe and reliable braking system, greatly improving the semi-electric stacker in the practical application of security.

     7 Chinese Dragon of semi-electric stacker with a special-link structure, greatly extending the service life of machinery, and easy maintenance.

Crane working operation precautions

Therefore, in the run-in period is likely to cause Crane parts (especially the mating surface) wear, wear faster. At this time, if the overload operation, it may cause damage to parts that Crane produced early failure.
1): Understanding lifting cargo size, central location to find cargo crane column distance from the center, according to the high lifting stacker capacity of the crane from the view parameters.
2): Crane lifting capacity (torque) is fixed, the larger crane working radius. Lifting cargo lighter, smaller working radius, lifting heavier cargo. (Working radius refers to the moment of the horizontal distance center to the hook.) -
3): Consider the size of the crane lifting capacity of the chassis size, the larger the better beam is selected, crane big and small chassis, will beam deformation and fracture. Small chassis, engine power is small, the impact of the forklift jacks capacity of the crane. Therefore, we consider the beam 230mm, you choose the 3 tons crane. When considering the beam 250mm, consider the following six tons crane. 280mm girders can select one of eight tons crane. Like the previous four after eight chassis can be considered under 10 tons crane.
Development Status
Situation abroad
Internationally Sweden, Italy, Austria, Germany, USA, Japan, Canada and other countries, more than a dozen companies producing dozens of scale models of truck mounted crane, mainly in Europe mainly. Europe from the 1940s and 1950s began producing truck mounted crane, major manufacturers have HIAB (Sweden), FASSI (Italy), FERRARI (Italy), PALFINGER (PALFINGER, Austria), TIRRE (Germany), HEILA (Italy ), etc.; Asian manufacturers are producing crane Kato (Japan), Tadano (Japan), Furukawa UNIC (Japan); American manufacturers are producing truck mounted crane GROVE and so on. These are the world's leading companies producing truck mounted crane, companies have formed a multi-function
