摘要： A modularized pedestal mount crane having a base frame with a pair of fore and aft extending flanges with a boom pinned to the forward end of the flanges and an engine is mounted on the rearward portion of the flanges. A winch frame, carrying a plurality of winches, is pinned to the flanges and extends over the engine with vertical links connected between the rearward end of the winch frame and the flanges. A gantry is pinned to the winch frame, and cat walks are cantilever from three sides of the base frame, a cab included on one cat walk.

摘要： A bulk material unloader includes parallel, spaced-apart main and back barges or pontoons which are held in fixed relationship with respect to each other by four collar frames. Two parallel cargo lighters are positioned between pontoons and the unloader is moored alongside ship. The two midship collar frames support a two-legged main tower over the main barge and a two-legged back tower over the back barge. A horizontal boom assembly includes a back bridge extending between the towers and an outboard boom supported by the towers and normally extending away from the back bridge and over the ship in parallel, end-to-end alignment with the back bridge. A horizontal bulk material conveyor assembly on the horizontal boom assembly includes two fixed parallel top horizontal endless belt-type conveyors supported on the back bridge and two parallel bottom horizontal endless belt-type conveyors supported on the boom assembly to move back and forth under the top conveyors and situated to receive bulk materials leaving the top conveyors. A chute is mounted at the outboard ends of the bottom conveyors, and bulk material deposited on the bottom conveyors is discharged into the chute for delivery to a hold of the ship. A bucket trolley and a grab bucket run on tracks which extend the entire length of the boom assembly. A hopper is situated on the back barge under the tracks so the bucket can deposit materials from the lighters into the hopper. An elevating conveyor carries materials from the hopper to the top horizontal conveyors. The chute is removable for offloading so the bucket trolley can move out to the outboard end of the outboard boom.
摘要翻译： 散装物料卸载机包括平行的间隔开的主和后驳船或浮船，它们通过四个框架相对于彼此保持固定的关系。 两个平行的货物打火机位于浮筒之间，卸载机停泊在船上。 两个中部衣领框架支撑主驳船上的双脚主塔和后驳船上的双脚背塔。 水平起重臂组件包括在塔之间延伸的后桥和由塔支撑的外侧起重臂，并且通常从后桥平行延伸并与船平行延伸，与后桥端对齐。 在水平吊臂组件上的水平散装物料输送机组件包括支撑在后桥上的两个固定的平行顶部的水平环形带式输送机，以及支撑在起重臂组件上以在顶部前后移动的两个平行的底部水平环形带式输送机 输送机和位于接收离开顶部输送机的散装材料。 滑槽安装在底部输送机的外侧端，并且沉积在底部输送机上的散装材料被排放到滑槽中以便输送到船舶的保持位置。 一个铲斗手推车和一个抓斗在轨道上运行，从而延长了悬臂总成的整个长度。 料斗位于轨道下方的后驳船上，因此铲斗可将打火机的物料放入料斗。 升降输送机将物料从料斗运送至顶部水平输送机。 滑槽可拆卸卸载，因此铲斗推车可以移出外侧舷外的外侧。

摘要： A crane structure mounted on a transport vehicle, preferably a marine vessel, is disclosed. The crane structure includes a gantry structure mounted on a vertical tower structure and having boom portions protruding from the tower structure. Preferably, the boom portions may be pivotally lowered from their operating positions and the tower structure may be rotated in a horizontal plane, thereby reducing the overall dimensions of the crane structure to allow transport under overhead obstructions and through narrow passageways.
摘要翻译： 公开了一种安装在运输车辆，优选船舶上的起重机结构。 起重机结构包括安装在垂直塔架结构上并具有从塔架结构突出的悬臂部分的龙门架结构。 优选地，悬臂部分可以从其操作位置枢转地降低，并且塔架结构可以在水平面中旋转，从而减小起重机结构的总体尺寸，以允许在顶部障碍物下方通过狭窄的通道进行运输。

摘要： The derrick barge comprises a pair of laterally spaced elongated hulls having a plurality of upstanding columns spaced therealong supporting a working platform and a heavy duty derrick or crane in spaced relation above the hulls. The hulls bouyantly support the vessel including its deck load in the floating condition with the hulls having freeboard. The hulls have ballast compartments to submerge the hulls and portions of the stabilizing columns to a distance of approximately one-half the effective height of the stabilizing columns to maintain the vessel in a semisubmerged floating condition with the platform and derrick elevated above the waterline. However, the vessel also may be ballasted or deballasted to submerge or emerge to a greater or lesser extent from the semisubmerged condition such that the distance between the mean water surface and either the underside of the deck or top side of the hull is not less than 0.75 of the mean wave height. The columns stabilize the vessel in the semisubmerged condition about roll and pitch axes. The heavy duty derrick is located adjacent the stern portion of the vessel with its vertical axis of rotation intersecting the vessel centerline. This novel twin hull column stabilized derrick barge arrangement has excellent motion minimizing characteristics under wave action in operations at sea.
摘要翻译： 井架驳船包括一对侧向间隔开的细长船体，其具有多个直立的塔，其间隔开支撑工作平台和在船体上方间隔关系的重型起重机或起重机。 船体在船体具有干舷的情况下，浮动地支撑船舶，包括其甲板载荷。 船体具有压载舱，以将船体和部分稳定塔淹没在距离稳定塔的有效高度的大约一半的距离处，以将船舶维持在半沉积的浮动状态，使平台和井架升高到水线以上。 然而，船舶也可能被压载或卸载，以从半浸入状态或多或少的程度淹没或出现，使得平均水面与甲板的底面或船体顶侧之间的距离不小于 0.75的平均波高。 这些柱子在关于辊和俯仰轴的半冲击状态下稳定船舶。 重型井架位于容器的船尾部分附近，其垂直轴线与船舶中心线相交。 这种新颖的双壳体柱稳定的井架驳船装置在海上作战中具有优异的运动最小化波浪作用下的特性。

摘要： A buoyant barge mounted crane has a vertical tower with a horizontal gantry. On the gantry is a cargo transfer assembly including a trolley and lift mechanism. A balance load is mounted on one end of the gantry, and the opposite end of the gantry is connected by a cable to a floating counterweight barge. As the trolley travels horizontally on the gantry, the counterweight barge maintains equilibrium of the crane through the transfer of weight through the cable.
