Forklift engine matching requirements

Widespread use of regional truck, climate varies greatly, poor working conditions, dusty, constantly changing conditions, heavy load. Therefore, the duo launched gas powered forklift and fuel economy should be operational reliability, long life good power, good cold start performance and ease of maintenance and repair. At the same time, also called compact structure, small size, in line with standards and regulations of the bad security indicators. Typically, a good truck engine should have the following basic characteristics:
    (1) able to adapt to continuous work and bear lasting than the load, the rated power for hours of power. Gasoline truck shall be equipped with speed limiter.
    (2) truck engine at work are often subject to greater impact and strong vibration, and thus the body and attachments should have sufficient stiffness and strength, and the mounting multi-use three-point support.
    (3) is guaranteed to work under varying load state of emergency, general governor should adopt the whole program, the instantaneous transfer rate should be less than 12%, stable transfer rate is less than 8%.
    (4) In order to meet ports, terminals operating environment requires greater engine torque adaptive torque reserve coefficient is usually greater than 12% (also excluding the torque converter).
    (5) To meet the needs of pumps and auxiliary equipment, auxiliary power output of the engine should be like home. For small and medium tonnage trucks, the hydraulic pump to be mounted directly on the engine, the auxiliary output power requirement is 50% -100% of the total power.
    (6) Lpg Gas Forklift often on sloping ground operations, require to be able to tilt the engine work around the state or around. Usually requires the engine can trim 20 & ordm ;, heeling 15 & ordm; state job.
    (7) Forklift often work in more air dust content of the environment. Requires a high efficiency air filter, fuel filler, vent and pipe joints should have a dust seal.
    (8) To meet the -40 & ordm; C- + 45 & ordm; C under a variety of climatic and environmental work, fuel, oil, grease, coolant, battery and other special requirements, and its related systems to make modifications. Cold regions to solve the problem of cold start, with the region have the potential to prevent overheating device.
    (9) In order to meet operational needs plateau region, should be set to reduce the compensation turbocharger power plateau, at an altitude of 1000-2000m require even 3000m regional job without reducing power.
    (10) of the truck in the tunnel, cabin operations, such as the environment, should exhaust gas purification device; wading depth work on a larger electrical equipment, such as YTO 2 Ton Battery Forklift have sealed their protection; there is gas in the work environment, the need for special explosion-proof facilities.
    (11) have high reliability and long life. New development should target forklift engine: diesel first failure of more than 800h. The first overhaul of 6000-10000h; target reference automotive gasoline engines.
    Emissions (12) truck engines, smoke, noise and other environmental indicators should meet national standards or industry standards and regulations in line with international standards as soon as possible.
    (13) The volume of engine power ratio, fuel and oil consumption, speed reserve coefficient, the minimum stable speed and mechanical vibration thinking technical performance indicators should meet the matching requirements of the truck.

Battery forklift procedures

Applicable models: the various models of battery forklift
1, to maintain proper startup boot speed, not too fast.
2, to observe the voltage voltmeter, if the voltage is below the limit, the truck should immediately stop running.
3, electric forklift trucks during walking, do not allow flip the switch to change the direction of the direction of travel, to prevent burn damage electrical components and gear.
4, travel and promotion should not be carried out simultaneously.
5, pay attention to the driving system, steering system is sound normal, abnormal sound to timely troubleshooting, prohibited ill job.
6, when the transition to slow down in advance.
7, when the poor road conditions in the job, it is important appropriate mitigation, and should reduce speed.
8, in the large slope road carriage of goods, the degree of attention firmly on the fork of the goods.
No.Symptom Cause Analysis
1. fibrillation occurs when lifting
A, lifting cylinders in air
B, the hydraulic system leak
C, inside the door frame, forks and wheel bearings for excessive wear size
D, two elastic uneven lifting chains
2, when a load fell fast freedom
A, piping and fittings have oil spills
B, multi-way valve, the valve hole / slide valve stem seals or wear, resulting in the leak.
C, supporting the lifting cylinder piston ring / Y-ring wear, resulting in the leak.
3, lifting speed is too slow or not lifting
A, lack of oil tank
B, filter clogging
C, hydraulic oil temperature is too high, hydraulic oil too thin
D, hydraulic pipeline leak
E, multi-way valve stem and valve wear
F, excessive wear of the pump Improper G, multi-way valve to adjust the pressure
4, Zhidongshiling
A, braking circuit breaker occurred
B, traction control brake friction plate electrode excessive wear
C, brakes loose or brake pad gap is too large
5, the electrical part of the fault, for example: battery 2 Ton Electric Forklift sudden lack of forward and back, lifting without any reflection, forklift dampen a walk, forward speed can not be adjusted, and so on.
The control section is very complex circuit, fault due to control problems caused by many, for there is no electrical maintenance personnel trained the best Do not repair, if the wiring mess, will have serious consequences. Recommended at this time with electrically controlled auto or truck production plant technician.
Some of the listed above are for reference only symptom. The reason car battery failure caused in the course are diverse, all manufacturers produce cars situation also varies. To make the car battery used in good condition, mainly because of routine maintenance, the failure nipped in the bud.
2 ton battery operated forklift precautions when handling stacking
One must know before lifting the weight, cargo weight must not exceed the truck 's rated load.
2, lifting goods packaged goods should pay attention to whether the firm bandage.
3. The cargo sizes, adjust the fork spacing, so that the cargo is evenly distributed between the two forks, to avoid partial load.
4, after the cargo door frame when inserted stockpiles should be leaning forward, cargo loading forks, mast should backward, so that the fork against the wall of the cargo and the cargo will be reduced as much as possible, and before traveling.
5, when lifting goods should generally be carried out in a vertical position.
6, during manual handling, you must use the hand brake, making the fork stability.
7, walking and lifting does not allow simultaneous operation.
