General Specifications:The GTC-700EX is a 70-ton telescopic boom crawler
crane with a boom length ranging from 11.4 m to 34.0 m. It measures 14.9 m in length, 5.72 m in width (tracks extended), and 3.22 m in height, with a gross vehicle mass of 61,542 kg.
Performance:
The crane offers a travel speed of 1.0 km/h to 2.8 km/h and a gradability of 68%. It features a 4-section full power synchronized telescoping boom system, with a retracted length of 11.4 m and an extended length of 34.0 m, capable of elevating from -1° to 78°.
Winches:
The main winch has a rope diameter of 19 mm and a length of 213 m, with a single line pull of 95.4 kN. The auxiliary winch has a rope length of 107 m and a single line pull of 78.1 kN.
Travel and Swing:
The crane includes a two-speed track drive system with skid steering and counter rotation, capable of 360° rotation with a swing speed of 0 - 3 rpm.
Load Moment Indicator:
Equipped with a standard rated capacity limiter and anti-two block system, it provides continuous display of critical parameters like boom length, angle, and load radius.
Engine and Hydraulic System:
Powered by a Cummins QSB 6.7 engine, delivering a maximum output of 194 kW. The hydraulic system features high-pressure pumps with a reservoir capacity of 1,136 liters.
Optional Equipment:
Options include a boom extension, boom jib, auger packages, and cold weather packages for operation down to -40°C.
Safety and Compliance:
The crane complies with EN 13000 requirements and is tested for structure and stability per ISO 4310. Operators must adhere to capacity limitations and general conditions for safe operation.
Specifications:
Specifications include lifting capacities based on FEM/EN 13000 and ISO 4305/EN 13000 standards, a maximum permissible wind speed of 13 m/sec, and various configurations for boom positions and counterweights.
Procedures and Safety Guidelines:
1. Avoid boom positions without rated loads to prevent instability.
2. Account for the weight of additional equipment like hook blocks and slings in rated capacities.
3. Telescoping the boom with a load is permissible within rated capacities.
4. Avoid side pull on the boom.
5. Do not exceed the manufacturer's maximum specified reeving.
6. Ensure proper crane configuration per the load chart before lifting or extending the boom.
7. Lifting capacities are subject to change without notice.
8. Consult the operator's manual before operating the crane.
Load Charts:
Includes detailed load charts for various crane configurations, specifying lifting capacities in metric tons for different boom lengths and angles, considering counterweight and track positions.
Recommendations:
Operators should use load moment indicating and anti-two block systems as aids, not replacements for thorough job site lift planning. Consider environmental factors such as ground conditions and weather.
