Safety specification of screw jack
Screw jack plays an important role in our daily engineering process. For each project, the main task is to ensure the safe operation of machines. Next, detailed information of safety operation of screw jack would be shown below.
1. The lifting platform using the screw jacks must be equipped with professional operators who have been specially trained, qualified, and certified.
2. Before operation, professional shall give a technical and safety explanation to operator. The main contents shall include: work contents and requirements, safety precautions and dangerous points; personnel division of work and their scope of responsibility.
3.Operator must be follow the maintenance requirements.After performing various inspections and maintenance, the lifting platform can be started. Working range of the platform truck should be checked and obstacles that hinder the rotation and walking of the platform shall be removed.
4. Staff should fasten safty belt while operating. When working in a charged region, car should be grounded according to the regulations. The lifting operation of platform should be carried out by person who in charge of the work. The person should contact the operator according to the standard requirements. The signal must be sent clearly and accurately.
5.Supporting is an important part for platform lifting, which determines the platform should be stand on the level ground. If the foundation is soft-grounding or undulating, sleeper must be adopted to make it work.
6. Platform should be lifting with the order of lower, middle and the upper arm.During the swinging operation, the lower arm must be lifted to a certain height then rotation could be performed. The rotation should be slow, and it is necessary to pay attention to the distance between cutting arm and platform to see if it meets the safety requirements.
