Finite Element Analysis

Finite Element Analysis (FEA), combined with computer-aided motion analysis software, allows our design team to eliminate structural “hotspots” where structural strength is critical to the long-term integrity of the product. Learn more.



Maximize your payload with super tough buckets made with strong materials including a T-1 steel mainframe and hardened, wear-resistant 400 Bnh bucket halves for heavy-duty material handling.

INCLUDED:

High-strength material to reduce unnecessary weight.

T-1 steel main frame.

360 ̊ continuous power rotation.

Hardened, wear-resistant 400 Bnh bucket halves.

Heavy-duty bearing and rotating motor.

Oversized, induction-hardened, heat-treated, and chromed pins.

Aluminum bronze bushings for extended service lubrication/greasing intervals.

Completely protected hydraulic components with access cover guards for easy maintenance.

(4) high pressure cylinders for greater closing power and structural stability.

Work tool-to-link pin.

OPTIONAL:

Crosshead link to interface with stick: includes stick-tip pin.

400 Bnh (or greater) cutting edges.

Quick change work tool system.

Fixed buckets also available in knock-about and non-rotating configurations.








Heavy-duty scrap handling meets its match with Pierce orange peel grapples. Hardened, long-wearing grapple tips complement the T-1 steel mainframe and AR400 grapple tines. Together, they deliver a tough-as-nails scrap grapple. Combine that with heavy-duty protection armor and four high-pressure cylinders for greater closing power, and you have a work tool designed for a high duty cycle and extreme applications.

INCLUDED:

360º continuous power rotation.

Heavy-duty bearing and rotate motor.

Oversized, induction-hardened, heat-treated, and chromed pins.

Aluminum bronze bushings for extended service lubrication/greasing intervals.br />
Completely protected hydraulic system with access cover plates for easy maintenance.

(4) high-pressure cylinders for greater closing power with heavy-duty protection armor.

Work tool-to-link pin.

Optimum arm shape to maximize payload.

2YD3 and smaller grapples designed to optimally fit into and unload dump trailers.

OPTIONAL:

Crosshead link to interface with stick: includes stick tip pin.

Quick change work tool system.

Fixed grapples also available in knock-about and non-rotating configurations.










Keep your motor running–and your work flowing–with generator packages specially engineered to power your magnets efficiently, while maximizing your payload.

INCLUDED:

Baldor Generator directly coupled to hydraulic motor.

Hubbell Controller with fusing 24-volt DC relay package.

Cab-mounted volt-meter magnet "on/off" indicator.

75' magnet cable and connectors, brackets, and mounts (as required).

Cab-mounted on/off system control.

Continuous oil supply from dedicated pump.

Convenient control handles.

Installation fully within 48”, 60”, 72”, or 96” Pierce cab riser or at right front corner location.

Installation inside 48”, 72”, or 96” Pierce riser or at right front corner location.

OPTIONAL:

Solid-state controller.



GENERATOR PACKAGES & MAGNETS
NOTES:

MAGNET & GENERATOR PACKAGE SIZES ABOVE SHOULD BE CONSIDERED GUIDELINES ONLY.
WEIGHT OF (CUSTOMER OR PIERCE SUPPLIED) MAGNET, AS WELL AS ENGINE PERFORMANCE (FOR POWERING GENERATOR PACKAGE) WILL DETERMINE FINAL CONFIGURATION.

ALL MAGNETS REQUIRE MAGNET LINK APPROPRIATE FOR INTENTED EXCAVATOR.

ALL MAGNETS ARE ALUMINUM COIL (UNLESS OTHERWISE STATED).

FOR GENERATOR PACKAGE INSTALLATION, MACHINE MUST BE EQUIPPED WITH APPROPRIATE AUXILIARY PUMP DRIVE.








Configurations Available:

Clamshell Bucket
3 x 3 contractor’s grapple (-C)
Forestry grapple (-F)
Rake (-R)


Go to extremes with Pierce power attachments specially made to stand up to the rigors of heavy construction, forestry, demolition, and extreme climate and work conditions. Pierce power attachments are perfect for ground level demolition, road building, and heavy-duty excavation.

All of our power attachments offer controlled articulation and positioning from the excavator’s bucket cylinder and linkage. They can be adapted to quick couplers for further versatility and offer proportional control for opening, closing, rotating, and other precision handling.


INCLUDED:

T-1 steel for superior strength and AR400 for abrasive resistant surfaces.

Common upper structure integrates lugging interface to any excavator.

Enclosed upper structure protects hydraulic components from debris and impact.

Bolt-on replaceable, serrated side edges.

Replaceable bucket teeth.

Common upper structure allows for interchangeability between various bucket/grapple tines, eliminating the need for multiple dedicated work tools.

Large diameter, HRHT 4140 alloy pins.

Aluminum bronze bushings.

360º continuous rotation.

(2) cylinders with high pressure seals.

'Valve in head' configuration minimizes machine's hydraulic requirements.

Open/close/rotate 'proportional' control (in lieu of 'on/off' control).

Momentary rotational float allows payloads momentum to pivot work tool.

Direct coupled rotate drive with double supported pinion gear and high output motor(s).

Rugged main bearing, large capacity through-bolted external gear slewing ring.

Easy access to all service and maintenance locations.

Front access door pivots open and main valve slides out for easy serviceability (shown below).

Bolt-on cover guards protect main bearing and other serviceable locations during operation.

Lugging for any excavator.

OPTIONAL:

Dual drive rotate motors.

Tool cylinder.






S.A. Technologies, a precision engineering company that specializes in advanced robotics & technology was commissioned to conceive a strategy & provide services & equipment required to run a full scale test of a nuclear reactor removal for the DOE. S.A. Technologies contacted Pierce Pacific Mfg. to design a specialized tool, a power clamshell bucket which S.A. Technologies engineers nicknamed T-REX. The test consisted of a number of elements & implements, but T-REX was to be the primary work tool. T-REX was mounted to a John Deere 850D in place of the standard digging bucket.

This clamshell bucket tool was designed to accomplish unique tasks while utilizing high forces and maintaining a small weight conscious package. The result is a tool that has been designed to achieve a very high performance factor to weight/size ratio. This bucket will primarily be used to dislodge and grapple materials that include cast iron slabs and blocks, structural steel, rubblized concrete, rectangular graphite bars, and miscellaneous tubes up to 4” in diameter. Occasionally the bucket will encounter materials that will require size reduction. The severing feature on the bucket will be used to facilitate size reduction without requiring a tool change to the standard shear.

Testing was successfully conducted at the S.A. Technologies site in Loveland CO August 16 – 20th 2010. T-REX exceeded performance expectations.
