We have been manufacturing telescopic marine cranes using rack and pinion system for over 20 years. The rack and pinion system is extensively used in elevating mechanisms 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 a 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). 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 Telescopic 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.
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.
Hydraulic Boom Lift Cylinders
Dual Drive Double planetary hydraulic winch is designed per API-2C and OSHA.
Double planetary hydraulic winch is designed per API-2C and OSHA
Safety system incorporated in the winch:
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.
Large Operators cab, HVAC, platform for diesel/hydraulic HPU with back walkway
The following components are visible to the operator at the control station:
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.
365 HP Tier 3 Diesel Engine
All high pressure hoses will have female JIC 37 degree flare fittings
All welds are per AWS D1.1 and all critical welds are tested (ultra sound and magnetic particle).
Price includes a thorough inspection and routine maintenance of all components of the TC150 Crane .
Price includes full factory test on Techcrane test stand and dismantling for shipment.
It is assumed that the current paint system on the crane in storage is acceptable.
Techcrane will reinstate 12 Month Warranty per our standard terms and conditions from the time of extraction.
We will extend the warranty an additional 2 months with our on site installation and commissioning team performing post delivery work. Quote will be furnished with further details of location of commissioning.
Based on current stock, the crane can be ready for delivery approximately 60 days ARO as quoted. One unit is available on a first come first serve basis.
Normal manufacture time is 6-8 months. Delivery is based on the availability of production slots which are given on a first come first serve basis. Delivery is determined at the time of order.
Per standard warranty 1 year after date of shipment.
