Forklift owners must see with terrible consequences of low-grade oil

Related to the use of fully synthetic electric forklift trucks engine oil and mineral oil advantages and disadvantages of different opinions, some say owners are easy to use fully synthetic, and some say the total synthesis has not imagined so good. Leaving aside the fully synthetic engine oil for the superiority of the engine, we first look at the long-term use of low-grade mineral oil and the consequences of not using antifreeze tank.

This is a Beverly 8V 1.4 dismantling the electrical forklift engine, the original owners of long-term use of oil as well as tens of dollars to use water as a radiator coolant, and long-term urban low speed, plus the maintenance cycle irregular lead less than 10 kilometers Wan last engine overhaul.

The engine has been completely disassembled

Carbon formation

The vast majority of vehicles currently on the market are already engine electronic fuel injection control, cylinder fuel injection works by first re-ignition at low speeds due to incomplete combustion, spewing gasoline can not be recovered, only to be attached the intake valve and combustion chamber walls, gasoline is likely to be volatile, but gasoline has stayed wax and varnish, wax and varnish long run piled thick, after repeated heating hardens to form a coke .

Wheel Driving Diesel Forklift engine crankshaft

Because long-term use of low-quality gasoline, oil, maintenance cycles are irregular and low speed main cause of carbon deposition.

Pistons coke

For the carbon on the piston is very easy to remove, but because of the piston continues to work, carbon is also very easy to longevity. By raising the speed of the shift can reduce the formation of coke, but can not be avoided. Like the picture on carbon through some sort of maintenance supplies additives have been difficult to remove.

Safety requirements for work trucks and hydraulic systems

First, forklift safety requirements working device

1. The mast shall be deformed and weld sealing off phenomenon, both inside and outside of the door frame roll gap adjustment should be reasonable and not greater than l. 5mm, wheel rotation should be flexible, wheel and axle should be free of cracks, defects. Round groove wear amount not greater than 10% of the original size.

2. Two lifting chain tension should be uniform, not distorted, end coupled solid, chain pitch must not exceed 4% of the original length, or should replace the chain. Sprocket rotation should be flexible.

3. Fork shall have severely deformed weld sealing off phenomenon. Fork surface without cracks, open seam welding phenomenon. Fork root angle not greater than 93 °, the thickness of not less than 90% of the original size. Left and right fork tip height difference must not exceed 3% of the fork length of the horizontal section. Fork positioning should be reliable, fork hook bearing surface, positioning surface no obvious defects, with the gap fork and fork frame should not be too large, and smooth movement.

4. lifting cylinders and connecting parts of the door frame should be solid, tilt cylinders and door frame, hinged frame should be solid, flexible, with the gap is not too large. Cylinders should be sealed, no cracks, smooth. At rated load, lOmin door frame from the sink is not more than 20mm, angle of no more than 0.5 °. Lifting speed at full load should not be less than half the standard value.

5. Overhead guard, backrest should be complete and effective.

Second, Lpg Gas Forklift Truck safety requirements of the hydraulic system

1. Night pressure system pipe joints solid, no leakage, and other parts do not touch the ground, rubber hose or aging, deterioration phenomenon.

2. The hydraulic system transmission components rated load, rated speed range should not be crawling, stagnation and a significant impulse phenomenon.

3. The multi-valve housing no cracks, leaks; be good and reliable performance; safety valve is sensitive, in 25% overload should be able to open, adjusting bolt nut should be complete strong. Operating handle positioning accuracy, reliability, not due to vibration displacement.

4. load curve, the hydraulic system should be complete clarity nameplate.

In recent years, rapid sales growth Forklift truck tyres

But professional forklift parts sales industry is not mature enough, most companies are selling forklift parts from the original forklift maintenance business derived from research and development and enterprise management level of the product is still quite backward, basically do not have the scale, reflecting out feature is the "quantity,

battery powered forklifts

 small-scale, low-grade" are homogeneous competition among many companies, disorderly competition, pursuing ism, right-hand man of trade, there is no business model, industry development Forklift truck tyres elastic extremely limited. Stone hills, Wheel Driving Diesel Forklift can learn from. Faced with this situation, the key parts of the enterprise may wish to make the world a fork with a giant TVH's management system used to study carefully open up its own development path in line with the characteristics of reform and innovation. In seize the opportunities, but also to assess the situation, based on the overall development of the industry, always concerned about the industry, the new situation, new changes, new trends, timely adjustment of enterprise development strategies, focusing on certain areas of product development, in order to become a true expert in the field belongs for the prosperity of the truck market to contribute!
