Promouvoir l’initiative « Ceinture et Route », réduire la pression réglementaire sur le gouvernement, économiser les coûts d’exploitation des entreprises et faciliter le commerce international.
Lifting hook: The rotating frame flipping device can realize the automatic fixation of the hook at the final position. During the user's use, it effectively saves time and labor when starting and ending the crane operating, greatly reduces the work intensity, and realizes easy operation.
Boom structure: The boom adopts a lower hexagonal cross-section, which effectively improves the bending resistance of the cross-section and enhances the carrying capacity. The boom body is built-in with a single-cylinder cable-pulled multi-section boom telescopic control technology, which is reliable and efficient.
Large span square box outriggers: The outriggers have a large span and can be used in a variety of working environments to improve the stability of the whole machine. Square box outriggers improve the outrigger support capacity and reduce the overall weight of the cylinder.
Operation: The turntable is operated by a high-position seat, with four-way operation and multiple operation modes to meet the needs of different customers.
Hydraulic system: Dual-pump proportional confluence hydraulic system, using compound action flow self-distribution control technology, linkage flow distribution is more reasonable, and compound operations are more efficient.
Safety device: Overwinding protection device. If the hook is overwinding due to the user's negligence or unfamiliarity with the lifting operation principle, the overwinding alarm device will promptly alarm and remind the operator to stop retracting the hook to prevent personal and property safety caused by wire rope breakage.
