Product Name: Stage Chain Hoist 

Product Type: Stage Chain Hoist 

Product Description: 

Tianjin Kemei Machinery Manufacturing Co., Ltd. is a modern production - oriented enterprise integrating independent R & D, manufacturing, and

 sales. The company's main products include stage electric hoist, stage chain hoist, black lifting slings, group controller, rail clamps, and auxiliary 

products. 

Product Specifications: 

1.It adopts international G80 - grade lifting chains, featuring good safety performance and corrosion resistance. 

2. It has two hoisting methods: normal hanging and inverted hanging. 

In the highly professional stage operation fields such as stage equipment installation, set adjustment, and lighting hanging, the stage hand chain hoist (manual chain hoist) has already become an indispensable key equipment with its unique and diverse comprehensive advantages, and its application range is extremely wide. Relying on its simple yet efficient mechanical structure, flexible and easy-to-control characteristics, as well as excellent and reliable safety performance, this equipment provides solid and powerful technical support and guarantee for various stage works. The main advantages and safety-related key points are elaborated as follows:

Key Points of Safe Operation and Maintenance

1. Regular Safety Inspections:

To ensure the safe and reliable operation of the equipment, it is necessary to strictly follow relevant safety standards, such as the specifications and requirements in GB/T 20957.1 - 2007 "Cranes - Safe Use - Part 1: General Principles", etc., and regularly conduct comprehensive inspections of the wear conditions of key components such as chains and hooks. With the help of professional measuring tools, such as chain elongation measuring instruments and hook deformation measuring instruments, accurately measure the elongation of the chain pitch. Once the elongation of the chain exceeds 3% of the original pitch, the chain must be replaced immediately. At the same time, measure the deformation of the hook. When the opening degree of the hook exceeds 15% of the original size, the hook should be replaced in a timely manner. Through these rigorous inspection and replacement measures, potential safety hazards can be effectively eliminated from the source.

2. Standardized Operation Procedures:

Operators must undergo professional skill training and be proficient in the operation procedures of the stage hand chain hoist. During the actual operation process, strictly follow the operation specifications and resolutely put an end to illegal operation behaviors such as overloading and diagonal pulling. According to relevant standards, the safe working load of the hand chain hoist generally ranges from 0.5 to 10 tons. Overloading operations will cause the stress borne by the chain and hook to exceed 1.5 times the allowable stress, which will not only accelerate the wear of components but may even lead to fracture accidents. Diagonal pulling operations will make the equipment unevenly stressed, greatly increasing the risk of equipment damage and posing a serious threat to the safety of operators and on-site personnel at the same time.

In conclusion, the stage hand chain hoist, with its stable and reliable performance, flexible and convenient operability, and relatively economical cost advantages, occupies a pivotal position in the field of stage technology and has become an indispensable important tool. Especially in small and medium-sized performances and in performance scenarios with high requirements for equipment control accuracy, it can successfully complete various stage operation tasks in an efficient and safe manner, playing an irreplaceable key role.
