The present invention relates to a truck mounted winch with crane (TMWC). More particularly, the present invention relates to an integrated wire line winch and a crane mounted on a heavy-duty vehicle having provisions for rotation of wire line winch and crane independently. Further, both the wire line winch and the crane draw power from the vehicle’s engine for their operations. Still further the invention ensures an operator will get an unobstructed view of well and operating assemblies during operations.

BACKGROUND OF THE INVENTION
Oil Industries perform several operations in producing gases, crude oil, paraffin waxes and other organic chemicals from oil well. These operations include side pocket mandrel operation, tubing scrapping operation, jarring operation, logging operation, production tubing maintenance operation, pressure/temperature surveys, reservoir studies, etc. These and other several similar operations are done using wire line, slick line or coil tubing. A well-designed wire line winch helps in achieving these operations efficiently at reduced costs, time and logistics and with small location footprint at a given well site. The wire lines are electric cables that transmit data about the well, consist of single strands or multi-strands and are used for both well intervention and formation evaluation operations. They are useful in gathering data about the well in logging activities, as well as in work-over jobs that require data transmittal. Further, at some sites slick lines are required to deliver and retrieve tools downhole. Slick lines are used to place and recover wellbore equipment such as plugs, gauges and valves lowered into oil and gas wells from the surface. They are also being used to adjust valves and sleeves located downhole, as well as repair tubing within the wellbore. They are wraped around a drum on the back of a truck. At working sites, sometimes the requirement is such that both types of winches and a plurality of winches are required to carry out various operations. These winches to carry out operations are either mounted on separate platforms and carried to well site in a single or more than one vehicle. But when there is requirement of more than one winch at site, it becomes inconvenient to arrange such machines.
CA 2547970 discloses a technique to facilitate a well related procedure involving perforation and fracturing processes. A crane is used to lower fracturing equipment into a wellbore. Additionally, a wire line winch is mounted on the crane to facilitate a perforation process. The wire line winch uses a conductive wire line that may be run into the wellbore to enable the firing of a perforating gun. The main drawback of this invention is that the tools used for rotation of winch require fasteners, weldments and bolts.
Patent application IN1673/CHE/2014 relates to a self-regulated engine operated winch which can be connected to any vehicle for loading of heavy objects including wooden logs. Using this invention, the driver of the vehicle alone can do the loading of heavy wooden logs. It is also used to lift the vehicles trapped in muddy dips and to take vehicles through steep rock cliffs and can be used to lift vehicles from such deep terrains without a driver. The multipurpose winch according to the invention operates by taking power from the engine of the vehicle itself. The main drawback of the invention is that the winch uses sprocket and gear arrangement for driving power and that makes the system complex.
CN203285333 discloses the full hydraulic rotation lifting vehicle-mounted drilling and work-over rig disclosed by the utility model comprises a chassis, an engine, a transmission auxiliary box, a winch and a derrick, wherein the engine, the transmission auxiliary box, the winch and the derrick are arranged on the chassis; the engine and the transmission auxiliary box are successively arranged on the rear side of a cab of the chassis, the derrick is arranged on the tail of the chassis, and the winch is a hydraulic winch; and a hydraulic pump, a radiator and a hydraulic motor are arranged between the transmission auxiliary box on the chassis and the hydraulic winch. The transmission auxiliary box drives the hydraulic pump to operate, the hydraulic pump outputs pressurized oil to drive the hydraulic motor, and the hydraulic motor drives the hydraulic winch. The main drawback of the invention is that the installation cost of the winch with the transmission auxiliary box is quite high.
Therefore, there is a need of a wire line winch that can be used for oil well operations like slick line operations, wax scratching, jarring and can also be used to provide depth, temperature/pressure surveys, and also rotates the winch to be used at different angles. Further, there is a need of integrating the winch with a lifting machine such as crane for lifting or lowering materials.

The crane 6 is also fitted with a hydraulic alert system to stop all the functions of the mast 21 when maximum capacity is exceeded on the telescopic boom 7. The crane 6 is rotated independently of the wire line winch 1.
The truck mounted wire line winch 100 uses a closed loop hydraulic system with variable displacement pump and motor. The hydraulic system is protected from overload by pressure relief valve (not shown). The only power source in truck mounted wire line winch 100 is the vehicle engine (not shown). The PTO takes an input power from the engine and provides different outputs to drive different equipments in the TMWC 100. One of the outputs of PTO provides power for hydraulic motor for driving the winch skid 2 and also for geared motor that drives the slew ring bearing 18 to achieve rotation of the wire line winch 1. Another output from the PTO is used to provide power for crane 6 operation. Still another of the outputs from the PTO is used to drive a hydraulic generator 11 for providing electric power for lighting, air conditioning etc. for operator cabin 5.
The winch skid 2 has air operated braking system with an adjustable non asbestos band brakes (not shown) for load holding. The winch skid 2 also has linear spooling system, and has capability for providing excellent jarring operations in both the directions. The winch skid 2 provides for chain drive reel through a closed loop hydraulic motor and step less transmission. The operator cabin 5 is an air conditioned cabin insulated from heat and noise to keep operator safe and comfortable, and for operator to get an unobstructed view of well and operating assemblies during operations. The operator cabin 5 of the wire line winch 1 includes a control panel with all the winch controls mounted on the panel. An electronic display is also available for digital display of depth, line speed, line tension and current time and date. An alarm setting is also provided to allow operator to set alarm to predetermined value of tension and depth and if the operator does not take any action on the preset alarm, the wire line winch 1 stops automatically at preset value. The data output of all gauges and meters are in metric configuration and are downloaded using a USB download port. The landline winch 100 is used for various slick lines such as but is not limited to 0.092”, 0.108”, 0.125”, 0.140” and 0.160” or braided line and e- line 3/16”, 7/32” operations.
Now referring to Figure 2, this figure provides details of the slew ring bearing arrangement 12. The slew ring bearing arrangement 12 comprises of a sub chassis ring 17 directly welded on the top of a sub chassis 16, a mounting plate 19 welded on the top of a sub chassis ring 17, a slew ring bearing 8 having ball (or roller) 18 and having an outer part 18b joined to the mounting plate 19 and an inner part 18a bolted to a base plate 20 and the base plate 20 is welded to the bottom of the wire line skid 1. The outer part 18b of the slew ring bearing is joined to the mounting plate 19 with the help of number of bolts equally spaced on the mounting plate 19. The inner part 18a has integral gears driven by a pinion mounted on a motor (not shown). The inner part 18a of the slew ring bearing, and along with that the wire line winch 1 mounted on the base plate 20, are driven by a geared motor which is mounted on the sub chassis 16. The geared motor is either driven by any type of power take off unit or any type of engine.
