|The top of this silo was nearly
rusted through in spots and the baghouse was not functioning very well
in addition to the poor shape of the railings. It was decided to
replace theentire top of the silo. The lid was fabricated on the ground with new railing, flange for new baghouse and and access hole in the centre. For installation, the new lid was made two inches smaller than the old one and a four inch flange of the old top was left for it to rest on.
This flange was inspected and found to be in good condition prior to
installation. The old lid and baghouse were cut away in pieces and the
new lid was lowered inside the old railings. After tack welding the new lid in place the old ralings were removed and the new bag house was installed. The lid was then welded solidly to the silo completing installation.
|A handbrake to allow the controlled
unraveling of a long (+50ft) tarp. The brake uses a multistage
mechanism to reduce over a foot of handle movement into a fraction of
an inch. A light pull on the lever translates into several hundred
pounds of clamping force at the brake disk.
|A wall mounted tarping
system to speed tarping and untarping of concrete forms. The bay this
system is in is not tall enough to allow all the forms to be covered
with a single piece tarp, so the tarp must fold itself in half as it is
raised. This folding action is achieved by cables running over wheels
at the base and at the folding knuckle in the centre. As the tarp is
lowered tension in the cable is increased and the outer tarp segment
extends. As the tarp is raised tension is decreased an the outer
segment retracts. A single cable running to each arm is all that is
needed to support and actuate the whole system.
|A guard to stop a front end loader from intruding into the walking/working area near a washout pit.|
|A picking bar for a forklift that allows it to move yard trailers and securely lift using chains or slings on the front latch.
|A braket for with electrical cord cleats attaching and adjusting effluent pump floats.|
basin to catch and collect spilled oil with covered access to sump
area. Designed to be buried with front lip at ground level, and back
lip against walls.
|A dolly modified to carry a
magnetic drill. It features an electrical cord cleat and top tray for
bits or accessories. The tab over the drill's carry handle and the tab
over the chuck work together and prevent the drill from tipping forward
out of dolly.
|A rolling set of railings to
allow workers to power wash and sandblast on top of precast concrete
NU-girders (a type of concrete I-beam) without having to wear a fall
The unit is made of left and right railing/wheel assemblies linked together by a square tube at the front and back. Pins allow for assembly without tools and replacement of the two cross tubes allows the railings to accommodate any width of NU-girder. Large diameter polyurethane wheels with ball-bearings allow it to roll on the rough top surface of the girder with little force.
