5. The Crane Control Group Locations
URW295CP1URS/P without Outriggers and Upperworks
The CCG is located on the carrier’s front
The Crane Control Levers are in- between the Outrigger Command Switches and Control Lever
Crane Control Group (CCG)
    The CRANE CONTROL GROUP (CCG) is located at the front of the SPYDERCRANE's carrier. There are THREE components to the CCG: 
The CRANE CONTROL LEVERS
The HOOK STORE SWITCH
The OVERWIND OVERRIDE SWITCH
    The Crane Control Levers are arrayed in-between the main body of the Outrigger Control Group and the Outrigger Control Lever.
    The Hook Store and Overwind Override Switches are located on the front end of the SPYDERCRANE's carrier, below the Outrigger Control Group.  
The Hook Store and Overwind Override Switches are on the front of the carrier

6. Crane Control Levers Boom Slew Boom Length Winch Control Boom Angle
    The Crane Control Levers are located on the front of the SPYDERCRANE, just to the roadside of the carrier's center-line. The Crane Control Levers are hydraulic valve controls connected to electronic servos.  Unlike the short Outrigger Control Lever, the Crane Control Levers can be pushed down and pulled up. 
    From left-to-right, the Crane Control Levers are: 
The BOOM SLEW CONTROL (the only lever with an orange knob)
The BOOM LENGTH CONTROL
The WINCH CONTROL
The BOOM ANGLE CONTROL
    The four Crane Control Levers are independent from one another, you can use one, some, or all four levers at the same time and control up to four crane control functions at the same time. 

7. The Symbol Decal on the end of the BOOM SLEW Control Lever
SLEW RIGHT/LEFT
Far-Left Control Lever
Will have an orange knob
The Symbol Decal on the end of the BOOM SLEW Control Lever
    The Boom Slew Control Lever is used to slew (or, swing) the boom of your SPYDERCRANE to it's right and left. 
It's important to remember that when we reference slewing the boom left and right, we ARE ALWAYS referring to the boom's OWN left-side and right-side.
The boom's back is where it connects to the BOOM TURRET and the front is where it terminates with the SHEAVE, or SHEAVES. 
To slew the boom RIGHT, you will PUSH DOWN on the lever. 
To slew the boom LEFT, you will PULL UP on the lever.
    Another way of think of boom slew, is that it slews on a turret that turns clockwise (right) and counter-clockwise (left). 
Pulling UP will SLEW LEFT
Pushing DOWN will SLEW RIGHT

8. The Symbol Decal on the end of the BOOM IN/OUT Control Lever
BOOM OUT/BOOM IN
The Symbol Decal on the end of the BOOM IN/OUT Control Lever
    You can control the length of the boom with the Boom Length Control Lever, which is to the right of the Boom Slew Control Lever.  When you PULL UP on the lever, the boom will telescope out, meaning that the individual sections of boom will slide out of the main boom section (called SECTION ONE). You SPYDERCRANE has either four, or five individual sections of boom (depending on your specific model of SPYDERCRANE).
To telescope the boom out (increasing the boom's length), pull UP on the lever.
To telescope the boom in (decreasing the boom's length), push DOWN on the lever.    
Pulling UP will BOOM OUT
Pushing DOWN will BOOM IN

9. The Symbol Decal on the end of the HOIST/WINCH-DOWN Control Lever
    Your SPYDERCRANE's hook is attached to the end of length of wire rope, that wire rope is spooled onto a drum located on the BOOM TURRET. To control the height of the hook, you need to control the length of the wire rope; that is controlled by the WINCH. To control the winch, you use the Winch Control Lever. 
Pulling UP will WINCH DOWN
The Symbol Decal on the end of the HOIST/WINCH-DOWN Control Lever
Pushing DOWN will HOIST

10. The Symbol Decal on the end of the BOOM DOWN Control Lever
BOOM UP/BOOM DOWN
    The boom is connected to the boom turret with the HINGE PIN (sometimes referred to as the FOOT PIN). A very large hydraulic ram (called the LIFT CYLINDER) is also linked between the turret and the bottom of Boom Section One. When you command a change in the boom's angle, you control the Lift Cylinder to push (or release) the boom which is rotating on the Hinge Pin.
When you PULL UP on the lever, you command the boom to GO DOWN.
When you PUSH DOWN on the lever, you command the cylinder to push the boom UP.
Pulling UP will BOOM DOWN
The Symbol Decal on the end of the BOOM DOWN Control Lever
Pushing DOWN will BOOM UP

11. PROPORTIONAL CONTROL Crane Control Levers employ Proportional Control
CRANE MANAGEMENT UNIT (CMU) controls motor RPM/flow-rate:
You DO NOT need to use the TCG Accelerator
You can execute all FOUR crane functions simultaneously
The CMU automatically balances supplied power based on lever position
    While the Crane Control Levers open and close the hydraulic valves that divert power to the individual crane functions, they are also linked to the CRANE MANAGEMENT UNIT (CMU), the SPYDERCRANE's central controller. When you move one of the levers, you actuate the related valve, but, the CMU measures how far you've moved that lever to determine how much power to direct to the related function. 
    For example, if you only slightly move the Boom Angle Control Lever, only a small percentage of the SPYDERCRANE's available power will be directed to changing the boom's angle. But, if you move the lever all the way to its stops, the CMU will run the hydraulic pump and engine at 100% and the boom will move as fast as it is mechanically able.  This PROPORTIONAL CONTROL is also referred to as AUTO-THROTTLE or INFINITELY VARIABLE VALVE CONTROL.
    Having the CMU ultimately control the speed and power of the various crane functions also means that you can control multiple functions simultaneously.
The MORE you move the lever, the MORE power the associated function is given

12. The Hook Store Switch Located below the OCG and CCG Control Levers
When activated:
Commands HOIST
Bypasses the A2B System
Activates 350 PSI cut-off
Activates Voice Warning Message
    Your SPYDERCRANE is equipped with a safety system called the ANTI-TWO-BLOCK (A2B) SAFETY. We will cover this system in more detail in a later topic, but, simply, the function of the A2B Safety is to prevent the hook from impacting the boom tip, either from you commanding a HOIST or by commanding a BOOM OUT WITHOUT commanding a WINCH DOWN.  When the hook is pinned to the boom tip (from HOISTING, or BOOMING OUT) it places enormous strain on the wire rope that the hook is connected to, as well as the crane's other working components. Prior to the widespread adoption of A2B Safeties in the crane industry, "two-blocking" was the leading cause of catastrophic crane accidents. 
    When you transition your SPYDERCRANE from Crane Mode  back to Outrigger Mode, you will need to safely stow the hook. The HOOK STORE SWITCH commands the HOOK STORE FUNCTION of your SPYDERCRANE, in part by overriding the A2B Safety. The proper boom and hook stowage procedure is identified in another topic, but, when you push (and hold) the Hook Store Switch:
The SPYDERCRANE commands a HOIST and overrides the A2B Safety. 
The SPYDERCRANE activates a 350 PSI relief valve. 
The SPYDERCRANE's VOICE WARNING SYSTEM announces "Secure Lifting Hook...“
   In practice, when you trigger the Hook Store Switch, you will see the hook slowly HOIST until it is pinned against the boom tip and is locked into position. The 350 PSI relief valve will engage once the hook is safely stored and the SPYDERCRANE will discontinue HOISTING (even if you continue to hold the switch). The SPYDERCRANE's CMU knows that the hook is safely stowed when the hook is hoisted into the boom tip and generates 350 pounds of pressure per square inch (triggering the relief valve).
The Hook Store Switch is used to command a HOIST until the hook is locked up against the Boom Tip; storing the hook while preventing two-block damage

13. The Overwind Override Switch
Located below the OCG and immediately below the Hook Store Switch
When activated:
Bypasses the A2B System
DOES NOT Activate 350 PSI cut-off
    Located just below the Hook Store Switch is the OVERWIND OVERRIDE SWITCH. While this switch looks like, and shares some of the functionality, of the Hook Store Switch, it has a very different purpose. 
    Another safety system that we will discuss in greater detail later in this lesson is the MINIMUM WIRE ROPE SAFETY. This safety is located at the boom turret, just forward of the winch. The Minimum Wire Rope Safety is designed to detect when there are less than three wraps of wire rope remaining on the Wire Rope Drum and to function kick-out (disable) the WINCH DOWN command when this occurs. Without the safety, an operator could continue to command a WINCH DOWN until the wire rope completely spooled off of the drum and either fell off (the wire rope is held to the drum with a friction wedge) or began to reverse course and begin spooling back ONTO the drum. 
    The ONLY time you would need to use the Overwind Override Switch is to override the Minimum Wire Rope Safety so that you can disconnect your SPYDERCRANE's wire rope and replace it. When you press (and hold) the Overwind Override Switch:
The Minimum Wire Rope and A2B Safeties are over-ridden (allowing you to command a HOIST without being stopped by the A2B Safety and a WINCH DOWN without being stopped by the Minimum Wire Rope Safety.  
The 350 PSI relief valve IS NOT activated.
There is NO VOICE WARNING SYSTEM announcement.
There is NO automated crane control function; you will need to command the WINCH DOWN using the Crane Control Lever WHILE holding the Overwind Override. 
The Overwind Override bypasses the A2B and Minimum Wire Rope Safeties; it is used when uninstalling the wire rope from the winch ONLY
