Group hanging electric hoist operation guide

Group hanging electric hoist lifting when subjected to the following irresistible external influences, there will be loads shake situation. The group hanging electric hoist load sway people and things will be a series of bumps, the load falls and other accidents, and will affect the group hanging electric  chainb lock  trolley running.
Do not lifting loads near the end of the beam side of the state to run. Lifting loads shake or fall will encounter people and things, may result in death or serious injury. Load if shaking, shaking the more powerful, the more difficult the operation of the car, accompanied by danger. In principle, to make the load lateral shake. Therefore, please observe the following.
1, not stayed
2, you need to move laterally, try to slow down, the slow running;
3, do not dramatic lifting loads
4, Do not lifting loads at the side of the state near the end of the beam to run;
Factors because of inertia in starting and stopping traversing the  lever hoist   even if the strict compliance with the operation, the load will vary shaking, proposed as follows.


1: Press the lateral movement by one: key "figure a", run the car begins to move, the load will be slightly delayed "Figure b"
2: In the load before going to swing to a central location, close button once;
3: When the load back to group hanging just below the hoist when the button is pressed again, "drawing c", so that lateral movement in this state.
Starting and stopping group hanging electric hoist lateral movement, even to comply with the above operation,Hoist and trolley lifting loads but also how much will be shaking. At this point, if the following operations will be able to reduce the lifting load sway.

How to replace electric chain hoist slip line

In cement and other building materials companies, electric hoists are widely used. Mill site electric  lift hoist  slip line faults have occurred, to overhaul the inconvenience. The following describes a replacement for your electric chain hoist slip line method.

1 electric hoist mounted on the U-shaped multi-track. For this characteristic, we track the cable arranged in the middle of the upper beam. 10mm wire rope or cable using vertebral round, ends with a basket of flowers bolt.
2 sliding ring is two rings linked together,chainb lock there is a certain margin in order to avoid cable scratch cards. Steering ring is connected to two ring bolts, freely.
3 Put a cover on the steering cable on one end ring, leaving a good motor lead wire after rubber ring fixed to the lower end of the steering. Then one end of a plurality of slip rings to wear to the tightrope, then rubber line segment fixed at the lower end of the slip ring.hoist and trolley Frontage motor, can rotate freely. After terminating the power supply.
4 in the traction motor to turn to the center ring, pulling cable in a straight line or circular motion.
5 straight track above method may also be used.

Electric chain hoist brake failure occurs, how to solve

Electric  Rope hoist  brake there are many, cone, electromagnetic, Pond's plane brakes and so on. Larger than the electromagnetic brake down, but when the production chain hoist less difficult and longer brake life. Pond's brakes and conical brakes, brake down a small amount of time to do the electric chain hoist high degree of difficulty, life is short.
Hoist the reliability is very high, because the electric  lift hoist  is used conical rotor brake structure, brake motor shell, radiator fan design, but together, connected to a hot cooling fan under the surface, braking and friction braking with the motor cover. When the brake pads wear serious contact with the rear brake, the braking skid. When the brake is refused or failed, they should immediately stop using, adjust the brake.
1, the no-load motor hood.
2, unscrew the three screws.
3, the fastening nut, pay attention to tighten the screws.
4 to reposition the screw, install the cover.
Adjustment, do not immediately use electric chain hoist,manual hoist you should first find a small object hanging tests, such as reduced or no braking in the case, in accordance with a hole, such as a better course of action, and then find the rated load adjustment weight, suspended tests.

How to remove chain hoists bearings

Chain hoists are installed equipment, cargo lifting, stationary objects, lashing and traction ideal tool for a variety of functions.  manual hoist  brought us convenience, but there are problems in the course is also more common to introduce you to the following chain hoists in case of bearing damage, how to remove?

1, with a round stick insert hands pulling hoist bearing bore inside the nose, the nose  chain block   and chain hoists inner bearing chock appropriated missing out after disagreements groove direction bearing chain hoists, chain hoists renewal check the chain hoists bearings or bearing is damaged;
2 Loosen the inner bearing chain  lift hoist  head bolts, will head chain hoists chain hoists inner bearing housings together with the removed;
3, loosen the chain hoists hex screws on the bearing points, if the chain hoists with eccentric bearing, then loosen the socket head cap screws, the chain hoists head against the direction of rotation axis eccentric to play loose.

Chain hoists key operation during use

Relative to the electric Wire rope hoist  is still relatively easy to operate, but to be safe, or pay attention to the relevant operating point.

Chain hoist wire rope hoist hooks and fixtures will be securely fixed, the chain was hanging heavy hook and reliably linked together.  manual hoist   lifting a weight. Pull the knob to position cards "on" and then flip the lever back and forth, back and forth with the handle pulled, the weight will steadily rise. Chain hoists heavy decline. Sign on the knob to "down" position, and then reciprocating lever handle, heavy as they pulled the handle and steady decline.
Chain Block hook position adjustment. No load to pull the knob on the indicator "0", and then turn the handwheel to adjust the chain hook the upper and lower positions. Ratchet pawl is disengaged, so that the chain is pulled by hand easily and quickly adjust the position of the chain hook.

PA mini electric hoist wire rope maintenance skills

1, wearing mini electric Manual hoist  rope pulley, there should be no rupture of its edges and gaps.
2, do not rope in motion relative to the friction and other objects, but should not be dragged steel edge oblique edges, so the edges cut steel wire rope.
     3, in the heat of objects using the rope must be used insulation measures, because after rope subjected to high temperature strength will be greatly reduced.
4, mini electric wire rope winch  during use must always check the strength of their rope, at least six months to conduct a comprehensive inspection or do strength tests.
5, the process of using non-overload should not be affected by the impact force required in bundled or lifting objects, be careful not to make the rope fast mouth directly and objects in contact with sharp edges in place to pad their contact with woodblock , canvas, burlap or other packing material to prevent damage to the object's edges and corners of the mouth rope fast to produce equipment and life accidents.
6, micro  hoist equipment  rope storage, according to the above methods to clean the dirt on the ropes after the Shang Hao lubricants, and then coiled good, stored in a dry place, in order to board underneath the rope or sleepers.
7, in the course, with particular attention to prevent contact with the wire rope and welding wire. Because of hitting power, the rope will be damaged, affecting operations smoothly.
8, note that checks whether the fracture failure situations or need to exchange a new rope, mini electric hoist to ensure safe use.
9, electric hoist in the course, where there is not long enough, you must connect using shackles, wire rope head wear is strictly prohibited methods take a long thin wire rope lifting objects, in order to avoid the resulting shear forces.
10, mini electric hoist in use for some time, the rope must add oil to prevent rusting steel wire rope, wire rope to reduce friction between.
