RT9150E OPERATOR MANUAL
OPERATING CONTROLS AND PROCEDURES
The following paragraphs describe the standard and optional controls and indicators located in the cab. Some machines may not be equipped with the optional controls shown. NOTE:
Many controls and indicators are integrated into the ECOS and RCL electronic controllers. Refer to either the ECOS Control Unit, page 3-17 or RCL Control Unit, page 3-68 for information on the cont rols a nd in dica tors in the se electron ic controllers.
The cab contains all the controls necessary for crane travel, parking and performing all craning operations.
OPERATIONAL AIDS
(i.e. buildings, towers, poles, etc.) in the crane’s working range. They are set by defining points along the outer limits of the working area with the tip of the boom. Once the working area has been defined, the system will provide a visual and an audible warning if the boom approaches a virtual wall.
CAUTION When defining virtual wall(s), always allow a safe working distance to any obstacles. Never work outside a safe working area as defined by common practice, standards, and manuals.
WARNING Electronic equipment on this crane is intended as an aid to the operator. Under no condition should it be relied upon to replace the use of capacity charts and operating instructions. Sole reliance upon these electronic aids in place of good operating practices can cause an accident.
Rated Capacity Limiter System The EKS 5 or Rated Capacity Limiter (RCL) is an electromechanical sensing system designed to alert the crane operator of impending capacity when the system has been properly preset by the operator. The control panel is mounted in the front console of the operator’s cab. When an overload condition is sensed, the system provides the operator with a visual and audible warning, and locks out the control levers to prevent lowering the boom, extending the boom, or raising the main or auxiliary hoist cables. Two additional features are included within the RCL system: •
Working Range Limitation
•
Anti-two-block Device
Anti-Two-Block Device This device is also incorporated into the system to prevent the hook block or headache ball from coming into contact with the boom nose or boom extension. This condition will also cause a lockout of hoist up, boom down, and telescope out, and also provide a visual and an audible alarm. Refer to the RCL Control Unit, page 3-68 for more detailed information on the function of the RCL system.
RCL Boom Alarm (CE Units) In addition to the audible warning in the cab, a visual RCL boom alarm is also mounted in the vicinity of the boom flood light to warn all personnel that a lockout has occurred.
Control Lever Lockout System
Working Range Limitation Refer to Working Range Limitation submenu, page 3-38. This feature allows the crane operator to describe the crane’s working area by setting up “virtual walls”. They are referred to as virtual walls because they exist in the system and are not real walls. The virtual walls represent obstacles
Grove
WARNING There are no cutouts associated with the swing angle set limitation or the work area definition features.
The control lever lockout system consists of hydraulic solenoid valves, located in the directional control valves. The valves are activated in such a manner as to prevent worsening the condition, i.e. boom down, telescope out, or hoist up. The control lever lockout system is used with the anti-two-block system and/or the RCL system.
