XCMG Official TZ2 Double-Boom Hydraulic Pilot Drill Jambo

1、Main Applications

It’smainly applicable for the tunneling operations of roadways and tunnels in minesand other underground projects.

Capableof drilling of blast holes, anchor rod holes, and undermining holes andinstallation of explosives, anchor rods, and air ducts.

Maximumoperation area coverage:104㎡.

2、Technical Features

（1）Drill jambo

Thehydraulic drill jambo adopts special structural process on the basis of thedomestic tunneling process to realize super-strong anti-bending capability,high drilling speed, and low drilling tool consumption and effectively improvethe working performance of tunnel side hole drilling.

（2）Propeller

Thelightweight high-strength alloy girder features high anti-bending,anti-distortion, and anti-fatigue performances and longer life.

（3）Chassis

It’sapplied with energy-saving, environmental-friendly, and low emission engine,powerful all-road all-drive self-adaptive traveling system, integral frame, andrear-wheel steering system, featuring high vehicle stability.

（4）Drill boom

Theall-directional paralleling-maintained drill booms of proprietary technologyfeatures accurate positioning. The drill booms adopt equal-strength structuredesign to realize reasonable structure, high strength, and long life.

（5）Drilling system

 The three-stage anti-seizure,anti-empty-drilling, and automatic return functions of drilling tool areprovided to effectively improve the drilling efficiency and reduce theconsumption of drilling tool.

（6）Centralized lubrication system

Thedistributor is applied to gather the difficultly accessible lubricating pointsto reduce the maintenance works.

（7）Hydraulic system

Theelectronic control design is applied for the auxiliary motions, includingoutriggers and roof lamp to simplify the pipelines and ease the maintenances.

（8）Electric system

The electric parts of world’s renowned brands,including Schneider, Siemens, Phoenix, Littelfuse, and Williams, are applied torealize high reliability and long service life. The production and warningfunctions, including grounding malfunction protection, phase sequenceprotection, digital current/voltage indicator, drill jambo impact timer, oilreturn filter blockage warning, motor thermistor protection, motor overloadprotection, engine malfunction warning, and transmission malfunction warning,are provided.
