VERSALIFT TMD-4060-T Digger Derrick, including the following items:
This section contains a brief description of standard components:
- Boom Assembly – The boom assembly consists of the lower boom, intermediate boom, upper boom, and extension system. The lower boom is constructed of high strength steel forming a 9.75 x 14.75 rectangular section. The intermediate boom is constructed of high strength steel forming an 8 x 12.13 rectangular section. The upper boom is constructed of high strength, filament wound, epoxy resin, fiberglass with a 7 x 11 rectangular section and incorporates a fiberglass tip. The extension system includes two double-acting hydraulic cylinders. Each cylinder incorporates dual counterbalance holding valves.
- Boom Lift Cylinders – Dual double-acting cylinders equipped with dual counterbalance holding valves and self-aligning spherical bearings. Each cylinder is capable of fully supporting the rated lifting capacity of the derrick.
- Turntable – The fixture welded steel structure is constructed from 5/8” plate wings and a 1.5” thick base plate. The base plate is machined flat to support the rotation bearing.
- Rotation Drive – Consists of a hydraulically driven planetary gearbox and spur gear acting on a shear ball rotation bearing. The gearbox incorporates a limited slip feature to protect the boom against excessive side loads.
- Turntable Winch – The 15,000 lbs. maximum capacity turntable winch consists of a worm gearbox, hydraulic motor, holding valve, and drum. At 40 GPM flow, the winch provides an average line speed of 50 fpm.
- Hydraulic Overload Protection – The overload protection is purely hydraulic and uses no electronics or electrical components. The system senses the boom lift cylinder pressure, When an overload condition is detected, the system disables the following: digger dig, winch raise, boom lower, upper boom extend, and intermediate boom extend.
- Continuous Rotation – Rotation is continuous and unrestricted in either direction.
- Pins, Bearings and Lubrication – The main pivot and cylinder joints use high strength hard chrome plated steel pins with fiberglass reinforced Teflon non-lube bearings.
- Open Center Hydraulic System – Full hydraulic units operate on an open center hydraulic system, open center tandem system provides 40 GPM for the digger and winch circuit and 15 GPM for the boom functions.
- Insulation – The fiberglass is certified for 46KV and below in accordance with ANSI A10.31 dielectric rating requirements.
- 52 in. Tall Pedestal – The pedestal is a fabricated steel structure incorporating a 1.5” thick top plate which is machined flat to support the rotation bearing.
- Digger/Winch Pressure Gage – The pressure gage on the lower control panel senses the pressure generated while using the digger and winch.
- Boom Pressure Gage – The pressure gage on the lower control panel senses the pressure generated while using the boom control valve.
- Custom Load Capacity Chart
- Engine Start/Stop Control – Operated by a toggle switch at the lower controls.
- Painting – The complete unit is primed and painted prior to assembly. The standard color is white urethane.
- Manuals – Two operator’s manuals and two service manuals are included.
This section contains a brief description of the additional options installed:
- Transferable Pole Guide – Can be pinned to either the upper boom tip or the intermediate boom. The pole guide includes hydraulic tilt and hydraulic operation of the pole claws. Holding valves are included to lock both cylinders in position.
- Pole Guide Interlock – Prevents upper boom from extending unless either of the following conditions is satisfied: 1. The pole guide tilt is fully raised. 2. Or the pole guide is properly pinned to the upper boom.
- Winch Line – 1” diameter x 140 ft. Stable Braid
- Swivel Hook – 5 ton rated swivel hook.
- Digger Assembly – Consists of the digger hanger and auger stow bracket. The digger hanger is automatically transferred from the lower boom to the intermediate boom when the auger is unstowed. The auger stow bracket includes an over stow protection valve.
- Digger Drives – Two-speed 12,000/3,000 ft-lb. Digger Drive w/ 2-1/2 in. hex.
- Auger Stow Sling – 7/8” diameter synthetic rope.
- Auger – 18” diameter auger with Rock Ripper Head.
- Kelly Bar – 72 in. auger extension for 2 ½ hex drive to 2 ½ auger
- Riding Seat Lower Controls with “T” Single Stick – Consists of a turntable mounted deck, seat, access ladder and control console. Includes full pressure, full flow hydraulic controls with a single handle joystick for boom raise-lower, rotate, and intermediate boom extend-retract. Additional hydraulic valve levers are included to control winch, dig, upper boom extend, pole guide tilt, and pole claw open-close.
- Throttle Control – Variable speed foot operated pedal used to control the engine speed from the lower control station.
- Tool/Pole Puller Tool Circuit – Consists of a ship-loose hydraulic sectional valve with integrated adjustable flow control and pressure relief. The 3-position control valve allows operation of a tamper or pole puller, while still allowing operation of the digger derrick at the same time.
- Sub-Frame – The full-length sub-frame is constructed of 6 x 6 square tubing and 5/16” plate. The pedestal mounts above the sub-frame allowing for possum belly storage. Shear plates are provided to attach to the vehicle frame.
- Main Radial Outriggers – Radial outriggers are designed and constructed from high-strength steel. At 6” (15 cm) of penetration the outriggers provide 180” (4.57 m) of spread based on 40” (1.08 m) frame height. Outriggers are equipped with pilot operated check valves, internal thermal relief valves, and separate operating controls for each outrigger.
- Auxiliary A-Frame Outriggers – A-frame outriggers are designed and constructed from high-strength steel. At maximum extension the outriggers provide 168” (4.27 m) of spread and 10.2” of penetration based on a 40” (1.02 m) frame height. Outriggers are equipped with pilot operated check valves, internal thermal relief valves, and separate operating controls for each outrigger. Slide pads at each leg ensure smooth operation. The standard pivot feet swivel a minimum of 10° each way.
- Outrigger Boom Interlock – The outrigger/boom interlock system is designed to prevent the boom from operating until the outriggers contact the ground. It also prevents the outriggers from being retracted before the boom is properly stowed.
- Outrigger Motion Alarm – an alarm will sound while the outriggers are in motion.
- Oil reservoir – 50 gallon bulkhead mount reservoir. Includes cleanout, 10 micron return filter that can be replaced without draining the reservoir, dipstick, 100 mesh (149 micron) suction screen, gate valve, and magnetic drain plug.
- Backup Pump – an auxiliary hydraulic pump to bring the booms down in case the main hydraulic source fails. This system consists of a hydraulic pump driven by a DC motor, which is powered by the chassis engine battery. It is designed for non-continuous operation.
- Slope Indicators – Slope indicators are required on VERSALIFT units. Slope indicators are installed to indicate the level of rotation bearing relative to the ground.
