Central Shanghai proof electric hoist is widely used in industries processing workshops, warehouses, docks, construction, various shops and a variety of shops and a variety of modern production lines, assembly line. Explosion-proof electric chain hoist is more flexible and quick to use in a small space in the workplace, safe and convenient. Explosion-proof electric chain hoist chain all use low-carbon steel, increased toughness and strength of the chain, can ensure the safety of the work. Explosion-proof electric chain block, good looks, compact, easy to install, wide adaptation, explosion-proof electric chain hoist with single-phase power supply, safe and reliable. Explosion-proof electric chain hoist for hardware, electrical appliances, small pieces of machinery processing, garment factories, restaurants, shops crane unloading cargo, or small high-rise building, logging, ideal warehouse handling tools.

Explosion-proof electric chain hoist overview

Explosion-proof electric wire rope hoists lifting equipment as one, proof chain hoist is a hoist, with its use of security technology is mature and stable, high efficiency, compact, explosion-proof electric chain hoist, light weight, small, when the plant is filled with explosive mixture, ensuring the safety of the premise is to improve working conditions, improve labor productivity powerful tool.
Explosion-proof mini electric hoist with high precision metal enclosure, high performance motor launch, while a double brake components to prevent heavy decline proof electric chain hoist to achieve zero decline, reverse the protective structure to ensure that in the case of a wrong power supply breakpoints do not work when burning motor, voltage protection ensure voltage stability, air fittings, not even electricity, carbon chain corrosion chain hoist, 360-degree rotating hook easily upgrade. Explosion-proof electric chain hoist class EEx de IC T4. Brass hooks, brass running wheels, anti-derailment copper roller, with fire flower function.

Manual winch

winch manufacturers: manual hand winch to hoist known as human as the driving force, by driving means rotating drum winch. Self-locking hand winch series: European style design, choice of materials known, Seiko welding products equipped with friction brakes, under gravity load, automatically turn on dual brake system, lifting the self-locking. Ensure the continued positive diversionary action to prevent load slippage.

The main suppliers are: electric windlass,  electric winch hoist, hydraulic winches, hydraulic winches Shanghai, construction hoist, building special hoist, Shanghai construction hoist, hoist frequency, frequency control winches, Shanghai frequency wire rope winch, manual winch,manual winch, hand winch, hand winch, hand winch Shanghai, manual winch series, Taiwan's small diamond electric hoist, a small diamond electric hoist hoist, a small diamond electric hoist (DU-160A small diamond electric hoist, DU-180A small diamond electric hoist, DU -230A small diamond electric hoist, DU-250A small diamond electric hoist, DU-300A small diamond electric hoist, DU-901 small diamond electric hoist and DU-902 small diamond electric hoist) and other hoist series.

Part of the wire rope hoist are: motor, transmission, drum and rope.

The wire rope winch of the motor and the spool can be roughly divided into four different types.

(1) The motor axis is perpendicular to the axis of the hoist drum using worm gear, large width aspect size, structure, heavy, low mechanical efficiency, more difficult process. Manufacturers currently have no such structure type of product.

(2)lift hoist parallel to the axis of the drum hoist, its
Advantages of small size, height and length. The disadvantage of a large width dimension, of the packet, manufacturing and assembly complexity. Track turning radius.

(3) The motor is mounted inside the drum hoist, the advantage of a small length dimensions, compact structure. Its main drawback is the motor cooling conditions are poor, poor groups, inspection, installation, maintenance, motor inconvenience, power supply unit complex.

(4) motor mounted on the outside of the drum hoist, the advantage is for the group is good, high degree of common, easy to change the lifting height, easy installation and maintenance.

PLC controlled mine hoist brake device

Mine hoist 1 ton chain hoist is an important protective device mine hoist. The braking device can be summarized as follows:

(1) at the end or lifting hoist not work reliably live gate hoist.
(2) speed hoist participate in the deceleration phase control.
(3) As a safety mechanism in the event of an emergency, to enhance the system protection.
(4) double drum hoist rope clutch when opening tune, replacement level, adjust the rope length, can live live drum brake, release the die roll to be adjusted rope operation.
     Currently 1 phase hoist brake disc brake mostly braking system consists of brake and hydraulic components. In the hoist operation use, although the design of the brake system tuning braking torque over multiple hoist static torque of three times, but still due to brake system failure caused over volume, squat cans and other accidents, causing serious economic loss.
     According to the analysis of the reliability of the braking system, brake system, brake disc causes of accidents caused by:
(1) hydraulic standing emergency braking, poor oil return pipe.
(2) hydraulic brake pressure regulator stability is not enough work.
(3) residual pressure is too high, the solenoid valve failure.
(4) brake failure, such as fatigue or rupture disc springs, brake shoe pollution caused by insufficient braking torque and so on. The electronically controlled part of the entire hydraulic station programmable controller (PLC), which will greatly improve the reliability of electronic control systems; and increase interaction with the field devices match the flexibility to achieve a variety of functional changes.
