What safety devices are there for light cranes? To ensure the safety and reliability of lifting operations, cranes are equipped with comprehensive safety devices to protect machinery or alert operators in case of accidents, thus providing safety protection. The working intensity of a cantilever crane is light, and the crane consists of a column, a rotating arm drive device, and an electric hoist. The lower end of the column is fixed to a concrete foundation with anchor bolts, and the cantilever rotation is driven by a cycloidal pinwheel reducer. The electric hoist runs left and right on the cantilever I-beam and lifts heavy objects. The suspended crane can be simply hung from the roof of a building or upper structure, and the crane track does not require additional support, making it easy and reliable to install, whether serving part or all of a workshop, at a lower cost. The single-beam suspended crane is composed of KBK standard components, allowing for quick and reliable material transport and accurate positioning of various components within a specific area. The lifting capacity can reach: 1000kg, with a span of up to: 6m. The main benefits of the suspended crane include a lifting capacity of up to 2000 kilograms, lightweight installation, safety, etc. Wire ropes are essential accessories for cranes, including phosphated wire ropes, galvanized wire ropes, and smooth wire ropes. 1. Overflow valves in the hydraulic system: These can suppress abnormal high pressure in the circuit to prevent damage to the hydraulic oil pump and electric motor or engine, and to prevent overload conditions. 2. Boom luffing safety device: In the event of an accident, if the high-pressure hose or oil pipe in the boom luffing cylinder circuit bursts or is cut, the balance valve in the hydraulic circuit will act to lock the working oil from the lower chamber of the cylinder, preventing the boom from descending, thus ensuring operational safety. 3. Boom telescoping safety device: In the event of an accident, if the high-pressure hose or oil pipe in the boom telescoping cylinder circuit bursts or is cut, the balance valve in the hydraulic circuit will act to lock the working oil from the lower chamber of the cylinder, causing the boom to retract automatically, thus ensuring operational safety. 4. Height limit device: When the hook is lifted to a specified height, it touches the limit weight, opening the travel switch (SQ), and the "overrun" indicator light will illuminate, simultaneously cutting off operations such as hook lifting, boom extension, and boom lowering to ensure safety. At this point, the operator can only lower the hook, retract the boom, or raise the boom to release the limit weight, restoring normal operation. In special cases where slight overrun operations are still needed, the release button on the instrument box can be pressed, at which point the limit function is released, but operations must be conducted with extreme caution to prevent accidents. 5. Leg locking device: In the event of an accident, if the high-pressure hose or oil pipe leading to the leg vertical cylinder ruptures or is severed, the bidirectional hydraulic lock in the hydraulic system can seal the pressure oil in the two chambers of the leg locking cylinder, preventing the legs from retracting or swinging out, thus ensuring the safety of lifting operations. 6. Lifting weight indicator: The lifting weight indicator is set on the side of the basic arm, allowing the operator in the control room to clearly observe it, accurately indicating the boom's elevation angle and the corresponding rated lifting capacity of the crane under specific working conditions. 7. Lifting characteristics table: Located on the lower wall panel at the front side of the control room, this table lists the rated lifting capacities and lifting heights for various arm lengths and working ranges for reference during operation. During lifting operations, the values specified in the table must not be exceeded. To ensure the safety and reliability of lifting operations, cranes are equipped with comprehensive safety devices to protect machinery or alert operators in case of accidents, thus providing safety protection.

4.

At this point, as long as the operator manipulates the hook to descend, the boom to retract, or the boom to raise, the limit weight will be released from constraint, and operations will return to normal. In special cases, if minor over-wrapping operations are still needed, the release button on the instrument box can be pressed, at which point the limit function will be lifted, but operations must be conducted with extreme caution to prevent accidents.

Leg locking device: In the event of an accident, if the high-pressure hose or oil pipe leading to the leg vertical cylinder ruptures or is severed, the bidirectional hydraulic lock in the hydraulic system can seal the pressure oil in the two chambers of the leg locking cylinder, preventing the legs from retracting or swinging out, thus ensuring the safety of lifting operations.
6. Lifting weight indicator: The lifting weight indicator is set on the side of the basic arm, allowing the operator sitting in the control room to clearly observe it, accurately indicating the boom's elevation angle and the corresponding rated lifting capacity allowed for the crane under that condition.
7. Lifting characteristics table: Located on the lower wall panel at the front side of the control room, this table lists the rated lifting weights and lifting heights for various arm lengths and working ranges for reference during operation. During lifting operations, the values specified in the table must not be exceeded.
