This 2017 SDP EZ Hauler 5500 Digger Derrick is a track-mounted digger derrick — sometimes referred to as a digger truck or pole-setter — a specialist piece of utility construction equipment designed to drill holes, set poles, and lift heavy loads in applications such as power-line installation, telecommunications infrastructure, and general utility work. SDP builds compact, track-driven digger derricks aimed at contractors who need the capabilities of a full-size utility rig in a machine that can access confined or difficult terrain.
At the heart of this machine is a Yanmar Minimax three-cylinder, water-cooled diesel engine displacing 1,640 cc and producing 25 horsepower at 3,600 RPM. The engine is fully Tier IV compliant. Hydraulic power is delivered by a fixed-displacement gear-type pump rated at 14 gallons (53 litres) per minute, feeding the crane, drive, and tool circuits.
The derrick offers a 5,500 lb (2,495 kg) lifting capacity with overload protection and a sheave height of 42 ft, with the boom reaching 41 ft (12.5 m) to tip height. The boom provides hydraulic elevation from +80° above horizontal down to -10° below horizontal and rotates a full 360° continuously, giving an unlimited work zone without repositioning the machine. The boom assembly consists of three hydraulically operated steel sections and one manually extended fibreglass section, and it incorporates a hydraulic pole guide. The auger is stored on the side of the boom with a latching mechanism for transport.
The auger drive uses a sealed planetary gear reduction system delivering 3,500 ft-lb (3,745 N-m) of torque as standard, with a 5,000 ft-lb option available. The standard auger bit is 18 in (46 cm) in diameter with a 2-inch hex output shaft, and a 2.5-inch output shaft is optionally available. A pin-on bucket with a 300 lb (135 kg) capacity provides a 44 ft (13.4 m) working height.
The machine is rated to 46 kV Category C dielectric specifications, making it suitable for live-line work at that voltage level. It meets or exceeds ANSI A, A, and SAE requirements. The machine is stable on side slopes up to 20° and is operated via a fully proportional wireless radio remote control covering both crane and drive functions.
Undercarriage is provided by rubber crawler tracks 12 in (30 cm) wide with five idler wheels per side, driven by integrated orbit hydraulic motors with single-stage planetary drive gears. The tracks are hydraulically extended for work and retract for transport. Steering is achieved through skid steering. The transport bed measures 47 in L × 35.5 in W (124 cm × 90 cm) with a carrying capacity of 3,000 lb (1,135 kg). The winch is equipped with 9/16 in, 100 ft polyester rope.
Overall dimensions with the crane fitted are 17 ft (5.2 m) in length, 51 in (132 cm) in width with tracks extended — narrowing to 35.5 in (90 cm) with tracks retracted — and 6 ft 10 in (2.1 m) in height. Chassis length is 10 ft 6 in (3.2 m) and chassis height is 47 in (103 cm). With outriggers fully extended, the machine spans 11 ft (3.35 m) in width and 13 ft 6 in (4.1 m) in length. The machine is located in Nebraska, USA, and is reported at only 128 hours of use with a custom-built transporter trailer, a bucket, hydraulic tools, and a transformer/jib winch included.
