Electric Rope Shovels 7495 HF

Product catalog summary

Specifications Overview:
The Cat® 7495 HF with HydraCrowd™ is an electric rope shovel designed for heavy-duty mining operations. It features a dipper payload capacity of up to 109 tonnes (120 tons) and a dipper capacity ranging from 30.6 to 61.2 m³ (40-80 yd³). The boom length is 20.4 m (67 ft), and the effective length of the dipper handle is 10.9 m (35 ft 10 in).

Weights:
The working weight with dipper and standard links is 1,442,274 kg (3,179,670 lbs), while the net weight without ballast or dipper is 1,059,056 kg (2,334,820 lbs). The general-purpose dipper weighs 80,603 kg (177,700 lbs), and the ballast, provided by the customer, weighs 302,614 kg (667,150 lbs).

Main Structures:
The crawler mounting has an overall width of 12.73 m (41 ft 9 in) with standard treads and 13.5 m (44 ft 3 in) with wider treads. The total effective bearing area varies with tread width, affecting ground pressure. The revolving frame is constructed from welded, impact-resistant steel.

Operational Features:
The shovel is equipped with a dual-motor independent drive for propulsion and a planetary gearbox for hoisting. The swing mechanism includes two planetary gearboxes with dual-output pinion shafts. The lube system features a single-line system with six pumps for lubricant and grease.

Optimal Working Ranges:
Key operational dimensions include a dumping height of 10.06 m (33 ft), a maximum dumping radius of 21.64 m (71 ft), and a cutting height of 17.8 m (58 ft 5 in).

Electrical System:
The shovel uses an IGBT Acutrol drive system with power requirements of 3 phase, 50/60 Hz, 7200 V. The average 15-minute demand ranges from 945 to 1,322 kW, with a peak power of 3,778 kW. The system voltage is nominally 7200 V.

Front End and Rope Data:
The boom is made of welded, impact-resistant steel with twin-grooved, flame-hardened sheaves. The HydraCrowd system uses a hydraulic power skid to move the dipper handle, with optional rope crowd machinery available.
