Versalift ET32NF

BOOM
Inverted T-cross section, 3 or 4-section telescoping type, extended and retracted proportionally by a double-acting hydraulic cylinder and cable-crowd system. Equipped with easily replaceable teflon-plugged nylatron wear pads for smooth operation.

1747C - 3-Section 19' 7,5" (6,0m) to 47'(14,3m)

1761C - 3-Section 24' 5" (7,4m) to 61' 5"(18,7m)

1770C - 3-Section 27' 3,5"(8,3m) to 70'(21,3 m)

1781C - 4-Section 24' 6" (7,5 m) to 81' (24,7 m)

Boom Point – Three non-metallic sheaves mounted on bronze bushings. Two removable pin-type rope guards.

Boom Elevation – Double-acting hydraulic cylinder. Working range from 8° below horizontal to 80° above.

Load Hook –5-ton (4,5 mton) capacity hook with heavy-duty swivel and weight is provided for single-line operation. 

Manitex 1703c Boom TruckHOIST
Maximum theoretical line speed 300 fpm(91mpm). Maximum theoretical bottom - layer line pull 11,500lb (5 216 kg). Two-speed planetary reducer with wet multi-disc spring applied, pressure-released internal brake and grooved drum. The lay away hoist is mounted to the back of the boom assembly.

Wire Rope – For 81' and 70' booms; 300'(91,4m) of 9/16" (14,3 mm) diameter 6 x 37 EIPS IWRC. 47' and 61' booms are equipped with 244'(74,4m) of rope.

SWING SYSTEM
Externally mounted, double-reduction planetary earbox driven by hydraulic motor. Maximum swing speed 1.5 rpm. Wet multi-disc is spring-applied, pressure released. Ball-bearing swing circle with external gear. 372° non-continuous rotation is standard.

OUTRIGGERS
A-frame link type, operated independently for precise leveling. Equipped with double-acting hydraulic cylinders. 11-1/2" (292 mm) x 15-5/8" (397 mm) pivoting pads. Bubble level located near outrigger controls.

MOUNTING
Pedestal and subframe are mounted to chassis by threaded rods and clamp plates. No welding, drilling or bolting to truck chassis is required.

Subframe – Torsion resistant, rigid 4-plate design mounted under crane full length of truck frame.

Rear Stabilizers – A-frame rigid design, clamp mounted under truck chassis by threaded rods and cross tube. Double-acting hydraulic cylinders operated independently for precise leveling. Fixed pad size 10-3/4" (273 mm) x 11-1/2" (292 mm) with flared leading edge.

Manitex CraneSingle Front Stabilizer (Option) – Mounted to truck frame at the front for 360° crane lifting operations. May require a full strength extended chassis depending on application, consult factory. Double acting hydraulic cylinder is equipped with an in-line relief valve to ensure proper float loading. Hydraulic circuit is operated from either operator station. Auto-retract feature automatically retracts the front stabilizer when the outriggers or stabilizers are retracted for traveling.

Rear Underride Protection – Supplied on factory mounted cranes. Fabricated structure mounted at rear of carrier. Complies with Bureau of Motor Carrier Safety Standard 393.86.

CONTROL SYSTEM
Dual operator stations are equipped with four single-lever crane controls arranged in accordance with ANSI B30.5 standards. Fully proportional control valves. A system pressure gauge is mounted on the driver's side console. Each station includes individual control levers for each outrigger and stabilizer for precise leveling. These control levers are shorter and positioned towards the center of the crane away from the main crane controls for added safety. Both control stations are equipped with engine start/stop, foot throttle, signal horn, boom angle indicator, load chart and range diagram. The pedestal is fitted with a ball mount on both sides for the moveable LMI display when this option is included.

HYDRAULICS
A 3-section pump direct-mounted to power take-off on truck transmission provides 35 gpm (132 lpm) to the hoist, 8.3 gpm (31 lpm) to the swing circuit and 18.3 gpm (69 lpm) to the remaining crane functions. A 70-gallon (265 liter) baffled hydraulic reservoir with strainer includes a 25-micron filter in the return line. Ball-type shutoff valve and strainer are provided in suction line. Use of SAE O-ring and face seal O-ring hydraulic fittings throughout system.

Hydraulic Cylinders – All load-holding cylinders are equipped with integral holding valves.

WARNING SYSTEMS
Hydraulic Capacity Alert System (HYCAS) – Hydraulically senses boom hoist cylinder pressure, audio warning indicates overload condition and overload shutoff feature prevents continuing overload. This system is standard on this crane series.

Manitex Boom TrucksLoad Moment Indicator (LMI) – CAN bus system maximize expansion capabilities. Senses boom hoist cylinder pressure, boom length and boom angle. Audio-visual warning indicates overload condition and overload shutoff feature prevents continuing overload. Operator can access all load conditions via display at the operator station. Features an internal boom length cable. This system is an option on this crane series.

Radio Anti-Two-Block System – Audible warning and shutoff functions prevent hook from contacting boom point.

Back-Up Alarm – Electronic audible motion alarm activated when truck transmission is in reverse gear.

GENERAL
Electrical – State-of-the-art, weather-resistant components throughout. Environmentally sealed enclosure contains accessory circuit, terminal striops and relays. System is protected by a supplied in-line fuse. Designed to withstand high pressure washing and varying climates.

Design/Welding – Design conforms to ANSI B30.5. Welding conforms to AWS D1.1. Tested to SAE 1063 and SAE 765.

Manuals – Operator, service and parts manuals depict correct crane operation, maintenance procedures and parts listing.

Warranty – 12-month warranty covers parts and labor resulting from defects in material and workmanship.
