A Frame Crane, Handling Rov Crane, Hydraulic Ship Crane manufacturer / supplier in China, offering 20t 30t Hydraulic a Frame Ship Crane Handling Rov, Container Type Bagging and Weighing Package Equipment, Dust Proof Hopper for Loading and Unloading Bulk Cargo and so on.
Product Description A-frame crane is kind of special lifting equipment, which is different from the normal slewing cranes, for it's operating and turning in the vertical plane, obtaining features such as high SWL, wide usage range etc. It's widely used inscience research ship, marine research ship, and engineering ship, serving as main supporting device for them.
There are 2 ways for its operating requirements and installation position. Shipstern A-frame Crane: it's mainly used for handling ROV, cable connection and deep tow. Futher more, it can be used for lifting steel structure and offshore installation. Shipboard A-frame Crane: it's used for geological sampling from seabed.
Shipboard A-frame Crane consists of 2 parts: A-frame structure and special winch, the latter can be customized according to operation requirements. Usually telescopic A-frame structure with adaptable height is equipped on Shipboard A-frame Crane for seabed geological sampling. Turning movement of Telescopic shipboard A-frame(outward ship or inby) can be done by luffing cylinder, while telescopic movement of crane can be achived through telescopic cylinder, for that, special oil pump unit needed. On A-frame structure have installed many kinds of assistant devices such as assistant winch, winch drum and guide pulley.
When Shipboard A-frame Crane works forSeabed Geological Sampling along with geological winch, sampling will be lifted to cabin directly. The working process as following: 1.For restriction of door frame of cabin, Shipboard A-frame Crane can only lift sampling into cabin under low position, its telescopic system can adapt its height. 2.A-frame crane will be stretched to max position to meet demand of larger working radius, when it works for seabed geological sampling. 3.A-frame crane will be drawback to minumum position to get through doorframe of cabin, when it handles geological samples into cabin. 4.After then, A-frame crane will be stretched to proper position to settle samples in right place.
Shipboard A-frame Crane is mainly used for seabed geological sampling, which works along with CTD winch, cable arrangement,high-intense guide pulley devices, tow winch and gravity sampling devices.

CCS/ABS/BV third party certification We offer the CCS/ABS/BV third party certification, which is recognized world widely .What the CCS/ABS/BV certificate tells: 1.the design all the productions drawings and the calculation is reasonable and meet the international standards.CCS/ABS/BV will audit all the productions drawings and calculation sheets before production. 2.The welding is good quality and meet the international standards.No damage detection report is required. 3.On site testing CCS/ABS/BV inquiry the safety rate is 1.25times, which means the actual lifting capacity is 1.25time the rated lifting capacity.And will issued exactly testing report according to the technical agreements.
Packaging Detail: Electrical parts are packed by crate wood,other parts are nude package ,or as client demand. Delivery Detail: If the size is suitable for container ship, usually by container; If the size is too big, usually by bulk ship or by container after truncation; Transport ways are based on reducing cost for you and keep the crane performance!
