Technical specifications for Spring box + counter spring manual operation system (SMS001)

This type of operation is ideal for smaller, lighter shutters where weight won’t be an issue. The spring-assisted roller door is balanced by a spring in the barrel, which is tensioned to adjust depending on the door’s weight and height. The door is simply “pushed” and “pulled” to operate. 

Technical specifications for Torsion spring manual operation system (SMS002)

• Torsion Spring: The torsion spring is a coiled spring that stores mechanical energy when twisted. It is typically made of high-quality steel and designed to provide the necessary torque to open and close the shutter door manually. The torsion spring must be carefully chosen to match the weight and size of the door for optimal performance.
• Shaft Assembly: The torsion spring is mounted on a shaft assembly, which acts as the central axis for the door. The shaft is typically made of steel and is mounted horizontally above the door opening. It is supported by brackets or bearings at each end to ensure smooth operation.
• Brackets and Mounting Hardware: The torsion spring system requires sturdy brackets and mounting hardware to securely attach the shaft assembly and other components to the building structure. These brackets and hardware should be made of corrosion-resistant materials to ensure the longevity of the system.
• Safety Features: The manual operation system should incorporate safety features to prevent accidents and injuries. This may include a locking mechanism to keep the door in place when in the open or closed position, as well as a manual release mechanism in case of power failure or emergency situations.
• Weight Capacity: The torsion spring and the entire manual operation system should be designed to withstand the weight of the door. The weight capacity will depend on the specific application and the size and material of the door. It is crucial to ensure that the torsion spring and operating mechanism can handle the full weight of the door to prevent excessive strain or failure.
• Maintenance: Regular maintenance is essential to ensure the smooth functioning of the torsion spring manual operation system. This may include lubrication of moving parts, inspection of brackets and other components for wear and tear, and adjustments to the spring tension if necessary.

Technical specifications for manual hoist chain operation system (SMS003)

• Hoist Chain: The hoist chain is a durable chain that is used to manually lift and lower heavy loads. It is typically made of high-strength steel and must have a sufficient load capacity to handle the weight of the load being lifted. The chain should be corrosion-resistant and properly lubricated for smooth operation.Chain Wheel or Drum: The chain wheel or drum is the component that the hoist chain wraps around. It is typically made of steel and is designed to transmit torque to the chain when operated manually.
• chain wheel or drum should have teeth or grooves that engage with the links of the hoist chain to prevent slipping during operation.
• Gearbox: The gearbox is a mechanical device that is connected to the chain wheel or drum. It provides the necessary gear reduction to enable easier lifting and lowering of the load. The gearbox should be durable, well-lubricated, and designed to handle the loads and forces expected during operation.
• Load Capacity: The manual hoist chain operation system should have a specified load capacity, which is the maximum weight that it can safely lift. The load capacity should be determined based on the strength of the hoist chain, the gearbox, and other components involved. It is important not to exceed the maximum load capacity of the system to avoid overload and potential accidents.Hand Chain: The hand chain is the component that the operator uses to manually operate the hoist chain operation system. It is usually made of steel and should be ergonomically designed for comfortable gripping. The hand chain should have a sufficient length to ensure smooth operation and provide the necessary leverage for lifting and lowering the load.Brackets and Mounting Hardware: The manual hoist chain operation system requires sturdy brackets and mounting hardware to securely attach it to the structure or support. These brackets and hardware should be made of durable materials, such as steel, and designed to withstand the forces and loads generated during operation.

• Load Capacity: The steel wire rope manual operation system should have a specified load capacity, which indicates the maximum weight it can safely lift. The load capacity depends on the strength and diameter of the wire rope, the drum size, and the gearbox's capacity to handle the load. It is essential to operate within the specified load capacity to prevent overload and ensure safe operation.Manual Operation Handle or Lever: The manual operation handle or lever is the component that the operator uses to manually lift and lower loads using the steel wire rope. It should be ergonomically designed and comfortable to grip, allowing for easy operation. The length of the handle or lever should provide sufficient mechanical advantage for the operator to apply the necessary force to lift and lower loads smoothly.
• Brackets and Mounting Hardware: The steel wire rope manual operation system requires sturdy brackets and mounting hardware to secure it to the structure or support. These brackets and hardware should be made of durable materials such as steel and designed to withstand the forces and loads generated during operation.Safety Features: Safety features are crucial to prevent accidents and ensure operator safety. Some common safety features in a manual operation system include a load limit device to prevent overloading, a failsafe braking system to hold the load securely when not in operation, and other mechanisms to ensure safe operation.
• Maintenance: Regular maintenance is necessary to ensure the proper functioning and longevity of the steel wire rope manual operation system. This may include lubrication of wire ropes and moving parts, inspection of the rope for signs of wear or damage, and adjustment or replacement of components as needed.
