Cat TH255C Specifications
The Caterpillar TH255C telehandler is a compact,
high-maneuverability lifting machine designed for construction, agriculture,
industrial material handling, and operations requiring performance in restricted
spaces. With a 2500 kg (5500 lb) rated capacity and a maximum lift height of
5600 mm (18 ft 4 in), the TH255C combines modern hydrostatic drive performance,
a powerful Tier 4 Final engine, compact dimensions, and excellent visibility
from the operator station.
Its versatile attachment capability through a
universal quick coupler further increases compatibility with a broad
range of work tools. The TH255C's engineering emphasizes reliability,
simplified maintenance, rugged steel chassis construction, and
multi-mode steering for precise load placement.
Technical Data
Engine model: Deutz TD 2.9L L4
Gross power: 55 kW (74 hp)
Maximum torque: 260 Nm @ 1800 rpm
Displacement: 2.9 L (177 cu.in)
Emissions: U.S. EPA Tier 4 Final
This 2.9-liter diesel engine delivers strong torque at low RPM for hydrostatic
drive systems. The direct-injection combustion system promotes fuel efficiency,
cleaner burning, and easier starts in cold climates. Cooling is handled by a
liquid-cooled system with a belt-driven pump, heavy-duty radiator, and
thermostatic regulation.
Transmission: Hydrostatic
Forward: Variable speed
Reverse: Variable speed
Travel speed varies depending on tires:
- 12 x 16.5 tires: 24 km/h (15 mph)
- 14 x 17.5 tires: 27 km/h (17 mph)
Axles
- Planetary front and rear axles
- High-bias limited slip differential on front axle
Brakes
Service brakes: Inboard wet disc brakes (front axle)
Parking brake: Wet disc, spring-applied, hydraulic-release
Indicator light alerts operator when parking brake is engaged.
System voltage: 12 V
Battery: 1 x 12V, 1000 CCA
Reverse alarm: Standard
Indicators include: machine hours, fuel level, steer mode, steering pressure,
battery charge, coolant temperature, parking brake, engine pre-heat
Lighting: front/rear cab-mounted lights (optional boom lights)
Drive configuration: 4WD full-time
Standard tires: 12x16.5
Optional tires: 14x17.5, 10.5x18, 33x12-20 solid non-marking
The chassis is compact and reinforced for heavy-duty operation. Its low overall
height allows entry into low structures and restricted indoor areas.
Steering type: Hydrostatic power steering
Modes: Two-wheel, Crab, Circle steer
Turning radius over tires:
- 12x16.5 tires: 3200 mm (127 in)
- 14x17.5 tires: 3100 mm (125 in)
Pump type: Gear pump
Maximum system pressure: 241 bar (3500 psi)
Maximum auxiliary flow: 72.3 L/min (19 gal/min)
Hydraulic system: 91 L (24 gal)
The hydraulic system powers boom lift, boom extension, tilt functions, and
auxiliary circuits. Load-holding valves ensure safe retention of loads.
Continuous-flow auxiliary hydraulics support work tools such as brooms or
hydraulic clamps.
