Introduction of common crane safety device – Knowledge

Crane Safety Device

Product Details: Crane safety devices are essential components installed on lifting machinery to ensure safe and reliable operations. Key devices include the over-hoist limiter, stroke limiter, automatic interlocking device, buffer, crane brake, weight limiter, and torque limiter. These devices prevent accidents such as over-hoisting, collisions, and overload conditions. For example, the over-hoist limiter cuts off power when the hook block is lifted too close to the crane frame, while the stroke limiter prevents collisions by stopping the crane at predetermined distances from the track ends or other cranes. The crane brake allows the crane to stop at any height, and the weight

limiter stops the crane if the load exceeds the rated capacity[1][3][4].

Pros:
– Prevents accidents such as over-hoisting and wire rope being pulled off
– Ensures safe operation by cutting off power when safety limits are exceeded
– Reduces the risk of collisions between cranes or with other objects
– Protects against overload conditions and motor overheating
– Provides precise positioning and control over the crane’s movements
– Enhances operator safety with features like emergency stop and remote operation

Cons:
– Requires regular inspection and maintenance to ensure functionality
– Can increase the initial cost of the crane due to the addition of safety devices
– May require additional training for operators to understand and use the safety f…
– Can add complexity to the crane system, potentially leading to more points of fa…

Crane Overload Device from China Manufacturer

Crane Safety Limit Switchs Manufacturers and Suppliers

what are the safety protective devices of the crane?

Product Details: Crane safety protective devices are designed to prevent accidents and ensure the safe operation of cranes. These devices include an overload limiter to prevent lifting beyond the crane’s capacity, a torque limiter to limit rotational force, and an anti-wind and anti-slip safety device to prevent the crane from sliding or overturning in strong winds. Other key devices include zero protection to prevent accidental start of mechanisms, an emergency switch to quickly disconnect power in emergencies, and interlock protection to ensure only one mechanism operates at a time. Additional devices such as deviation adjustment and display devices for gantry cranes, amplitude

indicators, wind speed alarms, and leg retraction locking devices for mobile cranes are also crucial. Conductive slide wire protection plates are used to prevent electric shock accidents[1].

Pros:
– Prevents accidents and ensures safe crane operation
– Protects the crane from damage due to overload, wind, or other external factors
– Provides multiple layers of protection through various devices such as overload…
– Enhances operational safety by preventing sudden starts and ensuring synchronize…

Frequently Asked Questions (FAQs)

What types of safety devices are commonly manufactured by crane safety device factories in China?

Crane safety device factories in China produce a wide range of safety devices, including overload limiters, torque limiters, anti-collision systems, load moment indicators, and electrical safety devices such as emergency stop buttons and travel limit switches. These devices are designed to prevent accidents, ensure safe operation, and protect both the crane and its operators.

How do anti-collision systems work in tower cranes manufactured in China?

Anti-collision systems for tower cranes use technologies like infrared and laser ranging to detect and prevent collisions between multiple cranes operating in the same area. These systems alert operators when cranes are too close, and in some cases, they can automatically stop the crane’s movement to avoid a collision.

What are the key features of overload limiters in cranes produced by Chinese manufacturers?

Overload limiters in cranes manufactured in China are designed to monitor and control the lifting load. They send an alarm signal when the load reaches 90% of the rated capacity and automatically cut off the lifting control power when the load exceeds 100-110% of the rated capacity. These limiters also record lifting times and weights, and they require regular calibration and maintenance.

How do electrical safety devices contribute to the overall safety of gantry cranes in China?

Electrical safety devices for gantry cranes include general power switches, earth leakage protection devices, emergency stop buttons, and warning lights. They also feature overload, overcurrent, and short-circuit protection, as well as overvoltage and undervoltage protection. These devices ensure the electrical system is safe and reliable, preventing misoperations and protecting the crane and its operators.

What other safety auxiliary facilities are typically included in gantry crane designs from Chinese manufacturers?

Gantry cranes from Chinese manufacturers often include additional safety auxiliary facilities such as inclined staircases, handrails, walking platforms, and protective covers for exposed moving parts like gears and chains. These features enhance the safety and convenience of the crane’s operation, ensuring personnel safety during construction and maintenance activities.
