FAQ of Construction Hoist

Q: What is the building hoist main purpose?

A: Building hoist equipped with double or single cabin to transport the materials and labors up and down. It's the ideal

construction equipment for vertical transportation in the field of construction.

Q: What is the main structure of building hoist?

A: The P/M construction hoist mainly contains metal structure, driving system, electrical control system, cable guide & protection system, electrical top crane and safety device.

Q: What is the meaning of the building hoist’s code?

A: Take SC200/200 for example: “SC” stands for rack and pinion hoist, “200/200” stands for double cage and capacity is 2 tons per cage. “SC200” stands for single cage and capacity is 2 tons.

Q: What is the dimension of the cage?

A: Normally the cage dimension is 3X1.5X2.5M (L/W/H) for 2t type hoist. Details should be checked according to our quotation sheet. Also, the size can be customized according to the factual site condition. There are two doors (entrance& exit doors) for each cage, It can be produced as up & down sliding or ramping model for safety and convenience.

Q: This question asks whether a building hoist can be utilized in both indoor and outdoor environments for lifting objects.: Yes, a building hoist can be used both indoors and outdoors for lifting objects. These hoists are designed to handle heavy materials and are often used in construction settings. However, their use is subject to specific conditions and safety requirements. Outdoor use may require additional considerations such as weatherproofing and stability in various weather conditions, while indoor use must adhere to space limitations and structural integrity of the building. Always ensure that the hoist is suitable for the environment and that all safety protocols are followed to prevent accidents.

Q: Is it possible to fix a building hoist or substitute it with alternative lifting machinery?: Yes, a building hoist can be repaired if the damage is not severe. If repair is not feasible or cost-effective, it can be replaced by other types of lifting equipment. There are various alternatives available, such as cranes, forklifts, and material hoists, each with its own advantages and suitable for different scenarios. The choice depends on factors like the weight of the load, the height of the building, and the specific requirements of the construction project. It's essential to consider safety, efficiency, and compatibility with the existing infrastructure when making such decisions.

Q: Is it possible to use a building hoist to lift objects that are too large to pass through a standard doorway?: Yes, a building hoist can be used for lifting objects that are too large to fit through a doorway. Building hoists are designed to handle heavy and oversized items, lifting them vertically through small openings or directly from the ground to higher floors. They are particularly useful in construction projects where large materials or equipment need to be moved to upper levels of a building. However, it's important to ensure the hoist is properly installed and operated by trained personnel to maintain safety and avoid damage to the building or the items being lifted.

Q: This question asks about the procedures and practices for regularly maintaining and inspecting a building hoist to ensure its safe and efficient operation.: Regular maintenance and inspection of a building hoist are crucial for safety and efficiency. It involves daily checks before use, including visual inspections for any visible damage, proper functioning of safety devices, and ensuring the hoist is clean and free of debris. Weekly inspections should focus on the mechanical components, such as gears, cables, and brakes, and checking for any unusual noises or vibrations. Monthly inspections may include more in-depth checks of the electrical systems and the structural integrity of the hoist. Annual inspections typically involve a thorough examination by a certified professional, who will assess the overall condition and safety of the hoist, ensuring it complies with all relevant safety standards. Always follow the manufacturer's guidelines and local regulations for maintenance and inspection schedules.

Q: Is it possible to utilize a building hoist for the purpose of moving materials up and down in a warehouse setting?: Yes, a building hoist can be used to lift and lower materials in warehouses. These hoists are designed for vertical transportation of goods and are particularly useful in multi-story warehouses where space is limited. They are capable of handling heavy loads and can be operated manually or with electric power, making them efficient for moving materials between different levels of a warehouse. However, safety measures and proper maintenance are crucial to ensure the secure and effective operation of the hoist.

Q: This question asks for the method to determine the maximum weight an electric-hydraulic lifting system can handle.: To calculate the maximum load capacity of an electric-hydraulic lifting system, you need to consider several factors: the hydraulic cylinder's piston area, the pressure rating of the hydraulic system, and the mechanical strength of the system components. The formula to calculate the maximum load (P) is P = A * P, where A is the area of the piston in square inches or square meters, and P is the pressure in pounds per square inch (psi) or Pascals (Pa). Ensure to convert units if necessary. Additionally, account for safety factors and the mechanical limits of the system to determine the practical maximum load that the system can safely lift without risk of failure.

Q: This question asks for the procedure to safely lower an object after it has been lifted using a building hoist.: To safely lower an object after using a building hoist, ensure that the area below is clear of people and obstacles. Slowly release the hoist's brake or control mechanism, allowing the object to descend gradually. Keep a steady hand on the controls to maintain a controlled descent. Monitor the object's position and communicate with ground personnel if necessary. Ensure all safety hooks and attachments are secure until the object reaches the ground. Once the object is safely on the ground, secure it and disconnect it from the hoist. Always follow the manufacturer's guidelines and safety protocols for the specific hoist being used.

Q: Elevator installation approach, need to give the total package (inspect) what data, come a master to answer the detail point: In ten days: installation company qualification (including business license, qualification certificate, safety production license, organization code certificate and company performance, etc.), installation personnel qualifications (including the principal, special operations personnel, etc.), installation construction scheme (including the construction organization design, safety and civilized construction scheme, construction progress) The installation process: in materials to submit for approval (material inspection report, certificate, etc.), play equipment to submit for approval (mechanical factory qualified certificate, safe use license, etc.) After the construction is completed, the certificate of safety inspection (which needs to be provided by the special security agency)

Q: This question asks for a comparison between electric and electric-hydraulic building hoists, highlighting their distinct features and how they differ from each other.: Electric building hoists are powered solely by electric motors, which provide direct and precise control over the lifting and lowering of loads. They are quieter, require less maintenance, and are more energy-efficient compared to their hydraulic counterparts. On the other hand, electric-hydraulic building hoists combine the power of an electric motor with the force amplification capabilities of hydraulic systems. These hoists offer greater lifting capacity and can handle heavier loads but are generally more complex, requiring regular maintenance of hydraulic components. They are also louder and may consume more energy. The choice between the two often depends on the specific requirements of the lifting task, such as load capacity, precision, and environmental considerations.

Q: This question asks if improper functioning or lack of maintenance in hydraulic cylinders can lead to damage.: Yes, hydraulic cylinders can cause significant damage if they malfunction or are not properly maintained. Malfunctions can lead to leaks, component failure, or even structural damage due to pressure surges. Lack of maintenance can cause wear and tear, leading to reduced efficiency and potential failure. Regular maintenance, including checking for leaks, ensuring proper lubrication, and replacing worn parts, is crucial to prevent damage and ensure the safe operation of hydraulic systems.
