A Safe Load Indicator (SLI) or an Automatic Safe Load Indicator (ASLI) is a device which is installed on mobile or portal cranes to alert the operator if the lift is exceeding the safe operating range of the machinery. [1] In some cases, the device will physically lock the machinery in circumstances it determines to be unsafe.
The XGC88000 crawler crane, unlike the majority of crawler cranes, comes in two sections. The primary section consists of the crane itself, which boasts a maximum boom length of 144 meters, a maximum total length of 173 meters (including the counterweight radius), a maximum height (when fully erect) of 108 meters, a lifting capacity ranging between 3,600 and 4,000 tons [10] [11] [12] (although ...
HLCV – heavy-lift crane vessel; HLO – heavy load-out (facility) HLO – helicopter landing officer; Hmax – maximum wave height; HNGS – flasked hostile natural gamma-ray spectrometry tool [17] HO – hole opener; HOB – hang on bridle (cable assembly) HMR – heating medium return; HMS – heating medium supply; hydraulic multipacker ...
The success of his hydraulic crane led Armstrong to establish the Elswick works at Newcastle, to produce his hydraulic machinery for cranes and bridges in 1847. His company soon received orders for hydraulic cranes from Edinburgh and Northern Railways and from Liverpool Docks, as well as for hydraulic machinery for dock gates in Grimsby. The ...
A mobile crane is a cable-controlled crane mounted on crawlers or rubber-tired carriers or a hydraulic-powered crane with a telescoping boom mounted on truck-type carriers or as self-propelled models. [1] They are designed to easily transport [2] to a site and use with different types of load and cargo with little or no setup or assembly.
Active heave compensation (AHC) is a technique used on lifting equipment to reduce the influence of waves upon offshore operations. AHC differs from Passive Heave Compensation by having a control system that actively tries to compensate for any movement at a specific point, using power to gain accuracy.
Other tine grabs use hydraulic closure with a hydraulic ram on each tine providing independent motion and improved penetration. The hydraulic supply and control is generated on the crane. Some grabs are electro-hydraulic, having an electric motor in the top girder which drives a hydraulic pump and all control gear.
