1DESCRIPTION
The NRC composite slider is a dream machine, a tough and versatile unit for recovery work and
extra-heavy towing. Specially designed for the most difficult tasks, the CS with its sliding
system brings you the best "USABLE BOOM CAPACITY".
This chapter describes the components of wrecker models 20CS and 25CS and lists their
technical specifications.
1.1 Description of the wrecker and its components
NRC CS wreckers are manufactured with the same main components and share the same
operation principles. Only their sizes and capacities are different. See Section 1.2 Technical
specifications for the CS wrecker model specifications.
The chassis comes in two models: the 20CS and 25CS.
Two underlift models are available and can be installed on the 20CS and 25CS models:
lHD-3: Heavy Duty – three-stage
lHDE-3: Heavy Duty Euro – three-stage
The following sections outline the chassis, boom and underlift characteristics.
