XL510 Gradall Low Roof Scaler (Spider No.2)
Scale ceiling (B) Scale face and rib (B) Scale ceiling (C) Scale face and rib (C) End of shift activities
1. Scale ceiling (B)
Begin scaling on the left side of ceiling scaling to the right side (clock wise)
Stop machine at desired location
Release tram pedal to set digger brakes
Set park brakes if condition warrants
Incline or decline
Pull up on park brake knob to set brakes
Raise boom to working height
Swing boom clock wise inspecting ceiling around scaler
If scale is observed, remove the scale
Position boom over left front tire by continuing to swing in a clockwise motion
Follow boom radius chart
Push right joystick right to swing right
Swinging left with boom lowered, creates a blind spot
Curl pick up by pushing the left joy stick to the left
Extend boom to area to be scaled by pushing right joy stick forward
Curl pick down when contact is made with ceiling by pulling left joy stick to the right.
This should create an approximate half inch impression in salt
Maneuver boom by rotating it if necessary to aid in knocking scales down and to see the tip of the pick
Push right joystick toggle switch left or right to rotate boom
Instructor needs to explain functions of boom roll
Extend boom while curling pick down and lowering boom (simultaneously)
This will create a scraping action across the ceiling knocking down the scales
Extend boom by pushing right joy stick forward
Curl pick by pulling left joy stick to the right
Lower the boom by pushing left joy stick forward
Boom should never be extended beyond half the telescoping range (approximately 23 feet)
This prevents unnecessary stress on the equipment and long term break down
Retract boom while curling pick up and raising boom (simultaneously)
Retract boom by pulling right joy back
Curl pick up by pushing left joy stick to the left
Raise boom by pulling left joy stick back
Swing boom right approximately 6 to 12 inches and repeat scraping process throughout boom radius (to the right tire)
See swing radius chart
Assure swing radius area is completely scaled
2. Scale face and rib (B)
Retract boom completely
Tram forward toward face (stopping approximately 5 feet from face)
Set park brakes if needed
Extend boom to the point where ceiling and face meets
Extend boom to area to be scaled by pushing right joy stick forward
Curl pick up
Curl pick up by pushing the left joy stick to the left
Scale face and rib by curling pick in a downward motion until pick break contact with face
Curl pick down by pulling the left joy stick to the right
This should create an approximate half inch impression in salt
Maneuver boom by rotating it if necessary to aid in knocking scales down and to see the tip of the pick
Push right joy switch toggle switch left or right to rotate boom
Instructor needs to explain functions of boom roll
Swing boom to the right (approximately 6-12 inches)
See boom radius chart
Assure boom radius area is completely scaled
Repeat the process from ceiling to floor within boom radius
Raise the boom to working height
Release park brakes if applied
Ensure there are no obstacles in travel way of scaler by rotating cab to right
Back away from face
Depress the base (heel) of the tram pedal fully
Tram approximately 80 feet from the scale portion of the face
Reposition to scale ceiling of left side of room (C)
Steer scaler to left side of room on an angle
See scaling diagram
Set park brakes if needed
