The DESMI crane sweeper is a diesel driven power pack complete with jib crane, self adjusting weir skimmer, DOP pump and wireless remote control.
It is designed to facilitate oil spill clean-up from the reaches of the crane jib and mobility of the flat bed trailer. The trailer has two large-diameter wheels making it easy for use in ‘off-road’ conditions and for reaching difficult to access areas such as pipelines and river banks. The DESMI crane sweeper is equally at home on the port or dock side to recover spilt hydrocarbons from the water.
The crane sweeper system is a combination of a 50 kW / 67 hp hydraulic power unit, knuckle crane and DOP-250 dual pump. The crane sweeper was originally conceived for pit cleaning operations where the abilities of the DOP-250 dual pump needed to be combined with the hydraulic power unit and a handling crane.
The crane sweeper is ideal for the recovery of oils in pits, ditches and rivers as well as harbours and heavily impacted shorelines.
The hydraulic cylinder at the end of the knuckle crane allows the orientation of the pump to be adjusted. Additionally the DOP-250 dual pump can be fitted with a self-adjusting weir assembly, this allows the pump to selectively skim oil from the water surface, and the crane supports the weight of the pump. The knuckle crane is mounted on a steel frame with the hydraulic power unit. Four outrigger legs with adjustable pads are fitted. Alternatively the crane sweeper can be welded or lashed to deck or truck. The pump or skimmer with the hoses can be lifted clear of the oil without manual assistance.
The DESMI self-adjusting weir can be removed in minutes and the unit can be used as a pump out system. This is especially useful to empty oil tanks or reservoirs that have been used for storage. The powerful DOP pump can handle both very light and very heavy oils. The power pack can run other hydraulic equipment such as other skimming devices as it is supplied with an additional number of hydraulic outlets.
The power pack frame is manufactured in steel and painted in marine grade high visibility orange making for a very strong and robust structure. In addition, it has ISO corners for easy securing to the trailer, during transport as well as during operation. It comes with lifting eyes in the top corners and forklift channels for safe handling.
The steel trailer is treated by hot dip galvanization steel and is supplied with a suitable tow bar complete with jockey wheel, over run and parking brakes. In addition, the trailer has four retractable and adjustable support legs for operations of the crane sweeper.
