Dynamic Load Line (lbs.) Static Load Line (lbs.) (*) Maximum capacity of this crane is limited to 60 tons Values Subject to Change Without Notice Rack and Pinion Telescopic Mechanism We have been manufacturing telescopic cranes using rack and pinion system for over 20 years. The rack and pinion system is extensively used in elevating mechanism of offshore drilling rigs and Jack-up boats. The inner boom is completely sealed and incorporates an internal stiffener. The rack is welded underneath to the center of the inner boom and a trough is built in on the top of the inner boom to accommodate the Anti-Two Blocking shuttle mechanism. The outer boom is open on both ends, sand blasted (inside and out) and receives three coat marine paint system on all surfaces. The gearbox(s) is mounted under the outer boom with the pinion gear engaged to the rack through an opening under the outer boom. The gear box is hydraulically driven using a high torque Charlynn motor. Internal disc brakes (in the gear box) as well as dual counterbalance valves hold the boom in place when the control lever is released (dead man type).

3 The same safety features that are incorporated in the jacking system of offshore vessels are used in the telescoping mechanism. Potential leakage in the internal boom cylinders are costly to repair and maintain. Telescoping mechanism on Our cranes use no hydraulic cylinder in the boom. Rack and Pinion Telescoping Mechanism Nyloil wear plates that are adjustable are used on all four sides between the inner and outer boom. The wear plates are manufactured from HMW nylon and are oil impregnated. All wear plates are adjustable and replaceable without the need to remove the inner boom. Mechanical boom stops are installed on the inner boom. As the inner boom is fully extended, the stops come in contact with external boom stops bolted to the outer boom flange. Removal of the inner boom is accomplished through unbolting the external stops from the outer boom flange and sliding the inner boom out. All bolts are secured by lock nuts.

4 Boom material: ASTM 588 or equal (50 kips). Fully retracted boom length is: 56 ft. Fully extended boom length is: 100 ft. One Boom Light mounted 30 ft from the heel pin.

As the lever is released, brake and counterbalance valve will lock until hydraulic power is applied. Direct access for lubrication of drum bearings. Reeving: 1 Part line 900 ft of 5/8 19x7 EIPS IWRC rope provided. To be used with Vendor Supplied Product. Overhaul ball with Johnson hook and safety latch provided Anti two blocking

Anti-Two Blocking Mechanism Our innovative anti two blocking system is virtually maintenance free, because of the use of stainless steel cable that transfers the signal from the boom tip to a valve

7 Anti-Two Blocking Mechanism Our innovative anti two blocking system is virtually maintenance free, because of the use of stainless steel cable that transfers the signal from the boom tip to a valve that is installed near the operator. No hose reel, hydraulic hoses, or valve at the boom tip is used in this system. With our anti-two blocking system load blocks do not creep upwards. Control Valve Operation Large Operators cab, HVAC, platform for diesel/hydraulic HPU with back walkway The following components are visible to the operator at the control station: Control function labels Load Capacity Chart Boom Angle Indicator Complete Load Monitoring System: Load and Aux Line, Extension, Angle, and Radius. Analog Indicator (3 Color Gauge) Our cranes are designed such that a correlation exists in the load induced hydraulic pressure in the boom lift cylinders, and overall stress in the crane. As the overturning moment is increased due to booming down, or hoisting a load (regardless of the load line or the fast line hoist) the pressure increases in the hydraulic cylinders. Unique to our design, a hydraulic pressure gauge with three color (green, yellow and red) dial is installed near the operator's console that monitors this pressure to indicate the safe working condition.
