System Description

ROTATING FLOOR
The rotating floor also utilizes a cellular design in its
construction for added strength and dent resistance.
Two large hydraulic cylinders connected to the j-link
rotate the door smoothly, allowing for precise
spreading of materials. The floor is designed with
close tolerances to the bowl for optimal material
removal, helping create a work alone piece of
machinery.
ELEVATOR ASSEMBLY
The elevator assembly
conditions and loads
materials into the
scraper bowl. The
assembly consists of an
elevator frame and
draft arms, a speed
reducer, sprockets,
chains, chain adjusters,
idlers and flights. The
upper corners of the
frame is designed with
a two piece steel casting that provides mounting for
the elevator drive system, as well as lever-type
elevator adjusters.
The frame incorporates draft arms which are used to
mount the assembly to the inside of the scraper
bowl. The draft arms, working in together with the
elevator adjusters, creates a mounting system that
protects the flights and cutting edge from rocks and
other large objects by swinging up, then quickly
returning back down to continue loading the bowl.
The flights are constructed of steel plates and
perform the actual conditioning and loading of the
materials. The flights are connected to dual drive
chains that are driven by a single high torque
hydraulic drive motor through the speed reducer.
