Trapezoidal Shape - Eliminates voids in the top of the dipper.
Rounded floor - Reduces drag in the face, and assists material flow.
Rounded floor - Eliminates the need for large heel and toe wear protection.
General Shape improves performance in sticky material.
Dipper Features
Rope Guard

Plate Lip
Micro Bail
Strong Door
Optimized Shape
Dual Side Latching System - Reduced door stress. Latch keeper outof high wear and impact area. Lower trip pull force required to open,and reduced maintenance.
Micro Bail - Advanced design methods have produced a lighter,stronger bail that is more favorably placed to increase maximumdump height allowing increased payload.
EPOCH Snubber - A Product developed and extensively tested byEpoch. It effectively, repeatedly and reliably dampens door closingand eliminates impact stresses.

Unique Ridge Back Design
Provides very high natural rigidity.
Deflects material during loading and reduces impacts.
Allows for larger underside support providing better loaddistribution on chassis.
Allows for a lighter, stronger design.Unique Canopy Design
Ultra - Strong Top Rail Design
Signature VR roundedcorner design
Load Body Shell
Shell features unique integral wear package design.thicker, harder sections are pre-assembled to form complete shell.
Total body mass reductions of 20% to 30% are achievable.
I- Beam Skeletal Design
Easier replacement of damaged or worn body shell sections.
