hoist equipment devices introduced

Hoist equipment including hydraulic system power unit, control and regulation devices, and other assistive devices. Sets can share a hydraulic hoist system.
.Hoist equipment hydraulic power unit generally, it is the mechanical energy into hydraulic energy. Hoist equipment Pump generally use positive displacement pumps, such as vane pumps and piston pumps. Vane pumps and piston pumps have a compact structure, smooth operation, less noise, long life and other advantagescan be high pressure, high flow, and the flow rate is adjustable. Recent years, domestic hydraulic hoist common use in high pressure, so in most cases, piston pump. Additionally,small electric hoist because the importance of hydraulic Hoist equipment hydraulic systems are generally set up two sets of hydraulic pumps, spare each other.

The main features of hoist equipment

hoist equipment sealing, less pollution gold ring, operation, easy maintenance, less wearing parts, low cost, due to less energy-efficient and maintenance, the use of low cost, reliable, advanced design principles to ensure reliable operation of the machine resistance, good sealing. Less environmental pollution.
Port construction Hoist equipmentt models, high accuracy. After hemming and intermediate casing beading, and then by welding, good rigidity, beautiful appearance, small mechanical dimensions, compared with an equivalent amount of other kinds of lifting hoist, hoist machinery such small dimensions. hoist equipment transport capacity, the series has NE15 ~ NE800 hoist a variety of specifications. The lift amount in the range of 15 ~ 800m3 / h. hoist equipment easy to operate, less maintenance,small electric hoist less wearing parts. Bush roller chain conveyor for induction gravity discharge, for a variety of powder, vertical lifting lumps Reap.

The main features of hoist equipment

Compact hoist equipment structure, the motor axis is perpendicular to the axis of the reel hoist using worm gear. Its disadvantages are: the length of large size, the size of the large width aspect,Hoist equipment clumsy structure, the low mechanical efficiency and the like and processing difficult. Hydraulic system for dual control, overflow valve, magnetic contact pressure gauge can be accurately controlled. Electrical control department uses a low voltage control, increased security dominate the system, manufacturers have no such structural type of product.
Structure and Characteristics: The machine uses a mechatronic design, the replacement of a different mold, you can suppress the different specifications of wire rope, domination is simple, safe. Its main drawback is the motor cooling premise is poor, poor grouping, inspection, device, easy maintenance motors, power supply unit complex.electric hoist trolley Electric motor axis is parallel to the roll axis of the electric hoist, wire rope electric hoist advantage of its height and length of the small size. Its disadvantage is that the large width dimension, the packet is poor, the manufacturing and assembly complexity.
Classification and description of the composition department wire rope hoist wire rope hoist are: motor, pass the idea of ​​structure, drum and sprocket. The mutual position of the motor and the spool can be roughly divided into four different types. Suppression of rope Rally, beautiful, fast, crimp a wire rope just a few minutes to complete,portable electric hoist
  greatly reducing the labor intensity, improve work efficiency.
Motor mounted on the outside of the drum hoist equipment, its advantages for the group is good, high degree of common, easily lifting height changes, device testing convenient.

hoist equipment major classification and application areas

hoist equipment is a special lifting equipment, installed in the crane, on the gantry crane,Hoist equipment electric hoist with small size, light weight, simple operation, easy to use features for industrial and mining enterprises, storage terminals and other places.
hoist equipment major categories: electric chain hoist, wire rope electric hoist (proof gourd),hoist manufacturers corrosion electric hoist, double drum hoist, hoist, mini electric hoist, electric hoist crane group, multi-hoist.
Application areas: promotion, pull shift, handling heavy loads, tank flip chip bonding, such as installation and moving various medium-sized concrete, steel, and machinery and equipment for construction and installation companies, civil construction and bridge construction factories and mines, electric power, shipbuilding,Hoist and trolley automobile manufacturing, construction, roads, bridges, metallurgical, mining, slope tunnels, wells and other infrastructure construction management protection of machinery and equipment.

three phase electric hoist pulley scrapped

Electric hoist crane pulley, metal casting, appear temporarily the following situation, should be scrapped:
three phase electric hoist  pulley
1) crack.
2) the wheel groove uneven wear loss reached 3mm.
3) wheel groove wall thickness wear up to 20% of the original wall thickness at.
4) because of wear of the wheel groove bottom diameter reduction of wire rope diameter 50%.
5) other damage of steel wire rope defect related issues.
Two, the ratio of electric hoist crane pulley diameter and the wire rope diameter shall be not less than the specified value.
Three, electric hoist crane pulley groove should be smooth, manual lever hoist no damage of steel wire rope defect driving.
Four, electric hoist wire rope pulley should prevent the device from the wheel slot.

How to prevent the cheap wire rope hoist is rust corrosion

There are a lot of cheap wire rope hoist  is made of metal parts, improper maintenance is easy to rust corrosion, thus affecting the whole life of the future use and therefore how to prevent rusting wire rope hoist is also a need for attention. 

1, wire rope hoist gearbox, anti-rust coating should contain barium petroleum sulfonate grease in the gear surface, and regularly check corroded and full protective film case. 

2, the part of the  monorail wire rope hoist   have been exposed surfaces and exposed machined surfaces and other corrosive threaded part, should smear grease or other calcium-based rust rust grease. 

3, the surface should be coated with anti-rust lubricant rope should wrap tarpaulin or plastic film in the non-operating conditions outside. 

4, the hook bearing grease to inject calcium-based rust to rust, and often checks. 

For rust corrosion has been the site, first with hardwood or bamboo pieces scrape rust re-oiled, such as the original film is damaged or deteriorated, the application of kerosene or gasoline to clean, apply a rust grease.‍

The basic classification of steel wire rope electric hoist

Part of monorail wire rope hoist are: motor, drive mechanism, the drum and a steel wire rope. The motor and the reel mutually different positions can be divided into four types.
(1) the electric hoist motor axis perpendicular to the drum axis with worm gearing, width of large size, heavy weight, low mechanical efficiency, processing more difficult. There is no manufacturers of this type of product.
(2) the motor axis parallel to the drum axis electric hoist, the wire rope electric hoist has the advantages of small size and length of the height. The disadvantage for large width, grouping, complex manufacturing and assembly. Orbital radius.
(3) the strong electric winch motor mounted on the inside of the drum, the utility model has the advantages of compact structure, small size. The main drawback for motor cooling condition is poor, packet difference, inspection, installation, motor maintenance inconvenience, power supply device complex.
(4) the electric hoist motor mounted on the outside of the drum, the advantages of good for grouping, high level of generalization, changing the lifting height is easy, convenient installation and maintenance. Its shortcomings: large size.
