Embodiment Construction
[0014] The function of this device is to increase the turning stability of the mobile crane with load, and solve the problem that some large mobile cranes cannot carry the load or walk at a low speed with a small load. Such as Figures 1 to 2 Shown:
[0015] Before applying this device, according to the installation position of the device, the tension angle of the stabilizer rod 1 should be calculated in detail and the hoisting should be in the vertical direction.
[0016] The stabilizing reinforcement bar 1 is connected with the sling, and it is ensured that the device is connected to the device by retracting and unwinding the ratchet winch 13 on the stabilizing reinforcing bar 1 before the hoisting 3.
[0017] The stabilizer rod 1 is located in front of the jib 5, and the two stabilizer rods 1 are opened in a V shape during operation. The stabilizer rod 1 and the boom are hinged, and there is a vertical luffing cylinder 9 between the stabilizer rod 1 and the jib 5. , the s...

The invention provides a device for improving the loading turning stability of a travelling crane. The device comprises a lateral stability stiffener bar, a steel wire rope, a suspended load, a suspended load pulling steel wire rope, a boom, a lifting steel wire rope, a slewer, a travelling device, a vertical derricking oil cylinder, a lateral opening oil cylinder, a connection transverse beam, an adjusting oil cylinder and a hoist with a ratchet wheel, wherein the travelling device supports the slewer which supports the boom, the boom supports the lifting steel wire rope and the suspended load pulling steel wire rope, the stability stiffener bar is articulated in the middle of the boom, the other end of the stability stiffener bar is provided with the hoist with the ratchet wheel, and the hoist with the ratchet wheel is connected with a sling through the stability steel wire rope; and the end of the lateral stability stiffener bar near the boom is provided with the connection transverse beam, the lateral opening oil cylinder is arranged between the lateral stability stiffener bar and the connection transverse beam, and the derricking oil cylinder is arranged between the lateral stability stiffener bar and the boom. The device improves the loading turning stability of the travelling crane, and the problems that certain large-sized travelling cranes can not travel with load or just can travel with small load and small speed.
Description
technical field [0001] The invention relates to a device for improving the turning stability of a mobile crane with load. Background technique [0002] For large mobile cranes, especially crawler telescopic boom cranes, the inability to ensure their stability when turning with load is the biggest problem restricting the crane's load capacity. Because the hoisting will generate lateral inertial force when turning with load, which will affect the lateral stability of the whole machine and make the whole machine prone to rollover. Contents of the invention [0003] In order to solve the problem that large-scale mobile equipment cannot carry a load or walk at a low speed with a small load. [0004] The invention provides a device for improving the turning stability of a mobile crane, which includes a lateral stability reinforcing bar, a steel wire rope, a hoisting load, a hoisting hoisting wire rope, a jib, a hoisting wire rope, a slewing device, a walking device, and a verti...
