Equipment installation and commissioning Before installing the equipment, you must read the product manual and provide training to the operators so that they understand the working principles of the equipment, precautions and safe operating procedures. They must not work without training. Assemble the hanging basket as shown in the diagram. The counterweight iron should be equipped with sufficient weight. The moment at the counterweight end should be three times the moment at the hanging basket end. Each connection of the moment arm should be strong and reliable. Check whether the safety lock is flexible and the pulley should be pulled briskly without any jamming. Check the elevator, press the electric button to make the elevator idle, and check whether the operation is normal. There should be no noise or jamming. Pass the safety rope through the safety lock and hang the counterweight. Start the elevator motor and thread the wire rope into the elevator. The rope end should automatically come out of the rope outlet. After assembly, the distance between the lifting rope and the safety lock should be adjusted.

The loading capacity of equipment using hanging baskets must not exceed the maximum lifting capacity. The electric hanging basket for high-altitude work is a piece of equipment designed for cleaning, painting and other operations on the outer edge of the building. It is strictly prohibited to use it as an elevator to ensure that the motor works intermittently. The motor must not operate continuously for more than 1 minute. If there is a power outage or the electronic control system fails, the motor release handle can be pulled to make the hanging basket gradually fall. When lowering and lowering, be careful not to drop straight down to the ground from a high place. Due to the acceleration of gravity, the hanging basket will fall faster and faster to prevent accidents. Because the motor speed has. The internal difference or the error of the mechanical part causes the hanging basket to occasionally become non-parallel. If the hanging basket tilts within the range, the safety lock will lock the hanging basket, so the operator should adjust the hanging basket to a horizontal lifting state at any time. Operators should observe the surface condition of the wire rope at any time. If it is found that there are broken wires, broken strands, external corrosion, kinked cross-sections and serious deformation, the wire rope should be replaced in time and should not be used anymore. If the safety lock of the hoist is found to be jammed or the sound is abnormal during construction, it should be repaired in time to prevent the equipment from being operated with disease. The user should apply to the production plant for maintenance once a year, and the production plant should keep maintenance records.

Manual hanging baskets for working at heights, pedal hanging baskets
Our company specializes in the production and sales of various construction hanging baskets, electric hanging baskets, manual hanging baskets, pedal hanging baskets, hand-cranked hanging baskets for working at heights, and hanging basket frames. Etc., factory price direct sales, users are welcome to call to discuss cooperation.
Equipment installation Before installing the equipment, first read the instructions. Check that when the prototype hoist is unloaded, the forward lever and reverse lever are continuously pulled, and the movement is flexible, light and free of jamming in the entire range. Check whether the safety lock handle is flexible and reliable when pulling. The suspension mechanism is installed as shown in the diagram, and each connecting screw should be tightened reliably. The counterweight iron should be stacked as shown in the diagram, and each concave and convex groove should be engaged to prevent it from loosening. The counterweight should not be lower than the minimum. Before inserting the wire rope into the hoist, first twist the yellow safety, and then move the release handle forward to the dead center. until it gets stuck. Thread the wire rope through the guide end, and then push the release handle back to its original position. At this time, the push lever will automatically return to lock the release system. To install the safety lock, first pass the safety lock wire rope through the safety lock, and then install it according to the diagram. It can move up and down flexibly.
Product introduction The hanging basket for working at heights is composed of four parts: a prototype hoist, a safety lock, a steel hanging basket and a suspension mechanism. The design standards comply with the mandatory standards of the Ministry of Construction. The manual hanging basket for working at height adopts domestic and foreign advanced technology and has a reasonable structure. Compared with hanging baskets of other structures, it has the characteristics of easy erection, simple operation, safety and reliability, various specifications, low investment and high efficiency.
The equipment uses the forward rod and reverse rod of the hoist to pull the hanging basket and safety lock up and down at the same time. The two operators should work synchronously to make the hanging basket run in parallel. The safety lock is a normally closed type. When the hanging basket rises, the safety lock rises at the same time. When the hanging basket falls, the safety lock cannot fall. The safety handle of the safety lock must be pulled downward. This allows the hanging basket to be lowered smoothly. If the lever hoist is found to be stuck or the sound is abnormal during construction, it should be repaired in time to prevent the equipment from being operated with disease. The stolen goods inside the gourd should be cleaned regularly. If the gourd fails to climb the rope, an appropriate amount of engine oil can be added to the gourd movement to lubricate the gourd so that the gourd can continue to work.
