How to install
Rope hoist , today I mainly on Rope hoist installation method
First, install chain hoist must first install the chain box;
Second, connect the power cord
Connect the power cord must be cut off in advance. Meanwhile ground should be well grounded, otherwise the operator touches any part of the chain hoist or when you are likely to feel a shock feeling.
Third, lubricate chain hoist
load chain
Chain lubrication level is a load chain life is an important factor. Timely and effective lubrication of the load chain, in order to ensure the effective life of the chain.
Fourth, check the chain arrangement
For multi-line chain Rope hoist, the hook should ensure that the next frame will not be overturned. If you flip it back to its normal state, to ensure the chain of weld arranged in rows. Do not twist the chain hoist hanging load.
Finally, check the operating voltage
Since Rope hoist factory, is based on a user-specified voltage or high voltage equipment (only dual voltage terms), such as 230/460V, need to check the wiring and make sure the power supply voltage requirements are met. If not, please refer to the manual must be corrected in order to meet the operating voltage requirements.
Tips:
Install Rope hoist, if improper voltage operation, may cause Rope hoistcausing serious damage. To prevent this from happening, you must ensure wiring meet the required power requirements.

If you avoid the wire rope hoist Kasheng
Wire rope hoist is stuck is one of the common problems and how to avoid the phenomenon of Wire rope hoist Kasheng it
Electric hoist occur frequently in the course of winding accidents. Especially when the card is in the drum and lift hoist the gap between the motor, the process is the only way off the motor, remove the rope. Time-consuming and laborious, but also delay the normal production, sometimes in order to maintain production, will be cut off welding wire rope, wire rope very easy to wear off leaving the drum and the motor housing, resulting in greater equipment accidents.
In response to these problems, through analysis, using a simple method to effectively solve this problem. In the inner plus welding a flange ring, so to prevent rope cards for various reasons the appeal site, without affecting the drum and motor assembly as well as the use of rope hoist performance. We are part of the hoist has been improved, with more than a year, the complete elimination of the rope stuck key issue. Production process, even if the phenomenon of chaos rope, because only in the hoist between the shell and the drum, through traction, easy way to increase the load, etc., within a short time you can handle. While maintaining the life of the equipment, without affecting the normal production.

Strengthen the Rope hoist equipment management
In order to effectively control
Hoist equipment personal injury, you should take the following measures to prevent:
1, strengthening the Rope hoist mechanical device employing security management. Strengthen education and training, improve operator safety awareness, safety skills to master, compliance, strict compliance with safety procedures and other safety management system.
2, to enhance the mechanical hoist equipment management. From the design, manufacture, installation, maintenance and other aspects of strict control, timely elimination of hazards, to ensure intrinsically safe equipment, through technical means to improve the degree of intrinsic safety equipment; equipment body meet safety technical requirements, safety accessory devices should be complete and effective. hoist equipment for some extended run, overload operation, some safety facilities not associated with the main equipment designed, constructed and put into use conditions, leadership and management departments at all levels should attach great importance to invest the necessary funds to expeditiously implement the rectification, the rectification former should take effective control measures.
3, strengthen the safety management of Wire rope hoist equipment. For Wire rope hoist mechanical characteristics, detailed safety rules and regulations, management system, ledger to complete. To implement the responsibility to reflect the "who's in charge, who is responsible," "who use, who is responsible" principle. System provides functional departments departments shall implement management measures to urge workers strictly enforce safety rules and related rules and regulations. For Wire rope hoist, and other special equipment should be regularly organized professional security inspection, investigation equipment problems, the problems identified should be implemented for the responsible units and persons responsible for coming up with feasible deadline for rectification and reform proposals. Functional departments of the rectification of the implementation, feedback and evaluation.
4, to strengthen the safety of field personnel operating process management. Accidents tend to be in a certain part of the job process on mistakes, such as the co-ordination efforts between the different types of defects, especially the lack of effective communication, confirm the work is not in place and other factors. Operation process safety management is in the process of production maintenance operations, through the process elements, the object element, time elements and spatial elements of system control, eliminating that may arise during the operation of the various dangers and harmful factors, to achieve safe production goals The key is to ensure the safety of the whole operation process specification, and reasonable.
Process validation system is to require operators to "judge, determined action" as a fixed mode of thinking, that is, in the course of operations are recognized by a certain way of operating, thus avoiding accidents.

Winter use Wire rope hoist Precautions
Winter should pay attention to the use of Wire rope hoist
In the cold winter construction process, especially in the snow, rope hoist circuit trouble, but rope hoist motor still does not start, because what is it
At this point the basic reason hoist brake ring froze to death because, if this Shihai forcibly boot, it is easy to burn the motor. So do not act rashly, the best solution is to open the motor cover, with a crowbar pry motor so that it can rotate freely can.
Simple operation will be able to extend the service life of rope hoist .
