Power Squaring Shears
Roper Whitney power squaring shears provide many choices of features
designed for shearing efficiency and accuracy to equal the demand of present day
productivity. Both the hydraulically operated (PH452 and PH52) models have built-in
ruggedness that will make them last for years of normal use. Within the many models
is the capability to shear up to 12 gauge mild steel and up to 6 foot sheet lengths.
Some models are designed for use where space is a consideration. All include precise
gauging and appropriate safety guarding.
* Max. Rated Capacity - 16 gauge (mild steel)
* 52" Shear Lengths
Compact, fully-integrated, hydraulically powered units. Ideal for many light gauge
shearing applications. Equipped with big shear operating controls. Fast, smooth,
oil-cushioned action. Both moving and fixed blades are shearing blades of Hi-Speed steel.
One piece cast shear bed is recessed for easy sheet handling. Standard equipment includes
back, front, and side gauges, bevel gauges, front arms and transportation finger guard.
Bed is machined for optional side extension squaring gauge.
Other Features
- Fully enclosed control panel, with magnetic starter, selector switch and relays
- Single or continuous stroke operation.
- Pressure relief valve to prevent overloading.
- Heavy duty foot switch. If released anywhere in the stroke, crosshead returns to "up" position.
- Electric solenoid hydraulic valving for instantaneous response.
- Dial stroke control - accessible adjustment with stroke length indicator.
- Hydraulic power uniformly applied through double-acting cylinders.
