What Is a Material Hoist?

Material elevator is a kind of mechanical conveying equipment with fixed device. It is mainly suitable for continuous vertical lifting of powdery, granular and small pieces of material. It is equipped with a rope break safety device, a docking safety device, a buffer device, an upper and lower height and a limit Devices, safety ropes and other safety protection devices.

Material elevator is a kind of mechanical conveying equipment with fixed device. It is mainly suitable for continuous vertical lifting of powdery, granular and small pieces of materials. It can be widely used in feed mills, flour mills, rice mills and oil mills of various sizes. , Starch factories, bulk storage of grain depots, ports and terminals.

Preparation of special construction organization design

The installation of material elevators is very dangerous. According to the "Gantry and derrick material elevator safety technical specifications" (JGJ88-92), it should be included in the construction organization design 1) project introduction; 2) selection of material elevators; 3) The main technical parameters of the material hoist; 4) the layout of the material hoist on the building structure plan; 5) the statistics table of the height and quantity of the material hoist; 6) the design description; 7) the mechanism; 8) the installation unit and Projects cooperated by both parties of the unit; 9) Construction process of material hoist; 10) Safety technical measures; 11) Seasonal construction measures; 12) Protection of finished products of the project; 13) Overturning safety factor check calculation; 14) Material hoist Technical knowledge and safe operating procedures; detailed configuration arrangements are also required. And has the approval of relevant departments. It is necessary to grasp the pertinence and feasibility of the construction organization design. According to the characteristics of the project, the optional material elevator can meet the construction requirements and ensure safety. The material elevator can cover the entire working surface as much as possible without leaving a dead angle. ^[1]

Control the entry of equipment

The equipment for the entrance should be consistent with the plan, and all kinds of accessories should be complete and intact and effective. It is also necessary to strictly review the entry list of materials, carefully check them, and compare them one by one. It is not possible to mix the material elevators between different models, and not to replace them with smaller ones, and to charge them better. ^[1]

Strengthen the monitoring of material hoist installation

In general, the material hoist enters the construction site in the form of parts, and it is important to monitor whether each material hoist is correctly assembled and installed according to the plan. It must be assembled firmly, the components are complete and intact, and the place of placement must be safe and reliable. ^[1]

Acceptance of installed material hoist must be performed

After the material hoist is installed, the site technicians, production staff and operators on the machine should be organized to conduct joint acceptance in time. Focus on controlling the installation position of the gondola, the assembly of the structure, the safety limit, and the flexible and intact condition of the electrical devices. There should be no obstacles to the running of the gondola. Acceptance must be 100%; when the quantity is large, it can be accepted in stages and written procedures can be formed. The hoist of inexperienced materials is forbidden to use. The problems in the acceptance must be rectified within a time limit, and put into use after confirming that there are no problems. ^[1]

Education and training of operators

First, operators are selected, and related education, training, examinations and certification are performed. Education and training focus on how to properly operate and use the material hoist and how to respond to and deal with possible emergencies to enhance the safety awareness of operators. It must also be emphasized that operators are prohibited from taking material elevators up and down to avoid causing harm to others. The person in charge of project technology of the construction unit shall provide the necessary safety technical information to the operator. ^[1]

Control daily management

The operator checks the mechanical and electrical systems of the material elevator every day before going to work to check whether the wire ropes and safety limits are intact. It is strictly forbidden to drink and work on the machine after confirmation. There must be special inspections during the operation. In the case of winds of class 5 and above, it is necessary to stop work and place the hanging cage on the ground to close it. All people except the inspection and maintenance personnel are prohibited from entering. When there are multiple types of cross-operations, a special person should be set up to take care of them. ^[1]

Dismantling and exit of material elevator

First of all, it is necessary to prepare the material hoist dismantling plan. It is necessary to know the order of material hoist removal, transportation method, demolition site, personnel configuration, weather and other conditions in advance. The necessary information must also be given to the dismantling personnel. ^[1]
