2 Boom Wheel Jumbo T2AM

Product catalog summary

Drilling Coverage and Performance
The document outlines the capabilities of a high-performance drilling system, emphasizing its enhanced climbing speed and improved braking distance. The system utilizes a Hydro-Static Transmission (HST) for easy driving and integrates a drilling control unit with the front frame for better driving performance and ease of operation.

Hydraulic Control System
The hydraulic control system is designed for simplicity, aiming to minimize downtime and reduce running costs through easy maintenance.

High Performance Drifter HD220
The HD220 drifter features a 20kW impact power and a dual damping system for high-speed and stabilized drilling performance. It includes a high-efficiency compact valve, durable rotation parts for large hole sizes, and a robust sealing system at the swivel part to minimize maintenance needs. The drifter supports high torque drilling with a proper mounting system.

Specifications
The document provides detailed specifications for the EURO Tier3 Engine, available in standard (Cummins QSB4.5, 119kW) and optional (Deutz D914L04, 58kW) models. The HD220 model has a mass of 187 kg, dimensions of 1003 mm in length, 306 mm in width, and 248 mm in height, with an impact rate of 2,900 to 3,800 min-1 and a rotation speed of 0 to 250 min-1. The drill hole range is φ45 to φ102 mm, and it features a dual damping system.

T2AM 2 Boom Wheel Jumbo
The T2AM model is detailed with an operating mass of 19,300 kg and equipped with two HD220 hydraulic drifters. It offers a drilling coverage of 6,185 mm x 6,420 mm, with an overall length of 11,650 mm, width of 1,980 mm, and height of 2,195 mm (operator roof lowered). The traveling speed is 0 to 12.6 km/h horizontally and 0 to 5.9 km/h at a 1:8 incline. The gradeability is 15°, with a minimum turning radius of 6,075 mm outside and 3,150 mm inside.

Engine and Power Line
The engine is a 4-cycle, 4-cylinder, water-cooled diesel model (QSB4.5) by Cummins, with a rated output of 119 kW at 2,500 min-1. It is certified Tier-3 for EPA emissions. The power transmission is via HST, with a 4-wheel drive system. The braking system includes axle-in 4-wheel disc brakes for working and mechanical drum brakes for parking.

Steering and Outrigger
The steering system features an articulated chassis with power steering and a steering angle of ±40°. The outrigger uses hydraulic cylinders for vertical hold, with four pieces included.

Electric and Other Equipment
The electric motor starts directly, with a recommended electric source capacity of 170 kVA. The power pack includes two 55 kW electric motors, a 7.5 kW motor for the air compressor, and a 5.5 kW motor for the booster pump. The electric power for the drilling line is AC400/440V (50/60Hz) or AC380V (50Hz), with a cable reel using a brush-ring method and a cable capacity of 100 m. The water booster pump delivers 240 liters/min at 73m.

Overview
The extension guide shell offers feed lengths of 3.4m and 4.0m, with overall lengths ranging from 4,087 to 5,897 mm, feed lengths from 2,180 to 4,000 mm, and rod lengths from 2,500 to 4,310 mm.
