Dump Hoist Type Comparison


Dual Ram Hydraulic Lift

Pros:

Dual Ram is simple and cost effective

Cons:
Less than 40% of the cylinders force to lift the load. The other 60% of the hydraulic force is absorbed by the frame and pivot points in the horizontal directions because of the "flat' cylinder angle when fully retracted. Increase wear on hydraulic cylinders, hydraulic pumps, hydraulic Hoses, battery and pivot points.


Scissor Hydraulic Lift

Pros:

Scissor lifts vary the speed with which they open; they move slowly in the beginnig when extra force is need and quickly later when the force is not needed. Scissor lift over other lift mechanisms pack a lot of travel into a small space - ideal for longer trailers. They also left, extend and retract with a quicker cycle time. The scissor acts as another frame or stabilizer to help increase the rigidity between the dump bed and the dump frame. Gravity Down does not drain any battery power when lowering the bed - that means more cycles a day for bigger jobs without draining your battery!

Cons: More steel and complexity in the hydraulic scissor frame adds to the cost.


Telescopic Hydraulic Lift

Pros:

The great advantage telescopic cylinders have over any other type of cylinders is their ability to provide an exceptionally long stroke from a compact initial package. Most force is in the initial stage when extra capacity is needed. Each stage will have less force, but raise faster allowing for a quicker cycle time. The best mechanical angle is when it is fully collapsed. This ensures 100% of the hydraulic force is being applied to the lifting the load and not causing extra stress in the frame or moving components of the dump. Like the scissor lift, Gravity Down does not drain any battery power when lowering the bed - that means more cycles a day for bigger jobs without draining your battery!

Cons:
With the cylinder being so large in the initial stages, there is increased time for the bed to raise to the full upright position. The telescopic cylinder itself is also more complex to manufacture, causing it to be more expensive.
