A hydraulic dump hoist is used during lifting and dumping applications through the use of either manual or automatic pressurized piston pumps and a hydraulic fluid reservoir. The hydraulic operation pressure of a dump hoist is predetermined by factory settings to allow maximum lifting capacity for the intended application.
Hydraulic dump hoists are truck equipment products generally intended for contractor or municipal markets and come in several varieties, depending on specific preference, needs and types.
The telescopic hoist, available for internal or external truck mounting, offers the lowest possible center of gravity and working height. It can be single- or double-acting with the ability to power up or power both up and down.
The underbody hoist is used with single-axle work trucks, allowing a maximum 50-degree dump angle.
A scissor hoist is used for lower center of gravity and greater load capacity applications. This type can take on multiple configurations depending on the truck's load and size capacity.
The original hydraulic high/low pressure volume system dump hoists are still utilized today. The advantages include reduced fleet size, ground level load and dump operation, quick 90-second drop off, dumping accuracy and full in-cab operation with no additional cables to break or unhook.
